David Lee Posted August 11, 2009 Report Share Posted August 11, 2009 Does anyone have a source for the the small oil seal in the AC Delco fuel mechanical pump? None of the repair kits seem to include it, neither Moss nor Rimmer Bros can supply it, and I have not yet been able to find a supplier on line. As replacement pumps are available presumably someone somewhere must be making the seals for them? Many thanks. Quote Link to post Share on other sites
brydon Posted August 14, 2009 Report Share Posted August 14, 2009 Hi Dave There's a guy who sells these seals who I only ever see @ the Tatton Park classic Shows, luckily the next one is only 8 days away! If Cheshire is to far for you to attend, let me know & i'll pick on up on your behalf. Kind regards Andrew Quote Link to post Share on other sites
David Lee Posted September 1, 2009 Author Report Share Posted September 1, 2009 Big thank you to Andrew who has managed to secure the seal for me. Now all I will have to work out is how to stop fuel from seeping out around the diaphragm. Any suggestions? Quote Link to post Share on other sites
ianc Posted September 1, 2009 Report Share Posted September 1, 2009 Three years ago, I was aware that my fuel pump was incapable of self-priming (I had to pressurise the tank to get the fuel into the pump) and that there was a very slight weeping of fuel from the diaphragm joint. I fitted a replacement diaphragm and seals from a Moss kit. Since then, the pump was immediately able to prime itself and there's been no sign of any fuel weeping from that joint.

BrianC Posted September 1, 2009 Report Share Posted September 1, 2009 (edited) Now all I will have to work out is how to stop fuel from seeping out around the diaphragm. Any suggestions? I have had this problem on my TR3A. The pump was stripped, cleaned and reassembled with all original parts when the car was rebuilt and was fine for the first 5000 miles. Then we started getting fuel pooling on the top cover. After ruling out the pipe union, we slackened off and retightened the six screws in the correct sequence and all was fine for about 200 miles, then the same thing happened. Repeated the exercise and once again after a few trips the problem reappeared. By now I was suspecting a porous casting, but also had a feeling the fuel was actually creeping up the screw thread, so as a last resort, I Loctited them and so far have covered about 600 miles without problems. Meanwhile, I'm planning to get a couple of overhaul kits and rebuilding a couple of spare pumps to carry one in each car on longer excursions - just in case.

I see you've been sorted out for a seal but just as an aside and for information for others. We have a pump kit over here supplied by Goss. Not sure if it's available in other countries or not but is a far superior kit to some of the other common brands you might see, it includes the oil seal gasket.. The Moss kits did not, at least not when I last bought one. Plus the pump diaphragm does not leak. Mychael Quote Link to post Share on other sites
David Lee Posted September 2, 2009 Author Report Share Posted September 2, 2009 The diaphragm is from a Moss kit and was fitted about 150 miles ago. One of the screws is missing its spring washer so that may be contributing. I was not aware that there was a correct sequence to the screws; is it in the workshop manual? I'll fit a new spring washer and try locktiting them down. Failing that I'll try a Goss kit from Oz. Thanks all. Quote Link to post Share on other sites
BrianC Posted September 2, 2009 Report Share Posted September 2, 2009 I was not aware that there was a correct sequence to the screws; is it in the workshop manual? I don't know if it's stated in the manual, but I always tighten any cover down starting at a central point on one side (longest if it's not circular like the pump cover) and working opposite and radially outwards (if you can understand that) as in the tightening sequence for cylinder heads. I also avoid tightening them fully on the first round. This avoids distortion and hopefully gives the most even torque (but then I'm not an engineer, so what do I know? ) Quote Link to post Share on other sites

gnotte Posted September 9, 2009 Report Share Posted September 9, 2009 Hello Dave and Andrew, did you record the name and phone of the guy who sells these seals @ the Tatton Park classic Shows. I need it too and would like to contact him. Thanks. Guy Quote Link to post Share on other sites
brydon Posted September 9, 2009 Report Share Posted September 9, 2009 Hi Dave When you have the pump stripped to it's component parts, check the mating surfaces of the pump casting are square and flat. Overtightning of the diaphragm screws will raise the soft aluminium material around the screw threads, effectively reducing the compression of the diaphragm at the mid point between the screws. Hope you fix the leak before the weekend. Kind regards Andrew Quote Link to post Share on other sites

David Lee Posted September 10, 2009 Author Report Share Posted September 10, 2009 Overtightning of the diaphragm screws will raise the soft aluminium material around the screw threads, effectively reducing the compression of the diaphragm at the mid point between the screws. Ahh, that may be the problem. My approach has been on the bigger hammer principle - to stop the leak I have been tightening them down as far as I dare without stripping the threads. Thanks again Dave Quote Link to post Share on other sites
David Lee Posted September 13, 2009 Author Report Share Posted September 13, 2009 Many thanks to Andrew again for sending the seal, the pump is now fully refurbished and the car saw some decent roads over the weekend. The fuel seepage from around the diapraghm turned out to be due to one of the screws having been overtightened, partially stripping the soft alloy thread of the pump base. A replacement screw with a fractionally larger diameter thread has worked a treat. Quote Link to post Share on other sites
badshead Posted September 23, 2009 Report Share Posted September 23, 2009 Did anybody have any success is sourcing this oil seal in the UK? I picked up a spare pump at Beaulieu for my 4A and need the oil seal to complete the rebuild. I've looked at the Australian solution mentioned above, but cost at £30+ is almost the same as buying a reconditioned pump Quote Link to post Share on other sites
gnotte Posted September 23, 2009 Report Share Posted September 23, 2009 Hi, probably yes, but the people who sale them is currently away for 2 weeks, as soon as I can contact him, I will post all the infos . Cheers, Guy Quote Link to post Share on other sites
gnotte Posted October 31, 2009 Report Share Posted October 31, 2009 Hello, Thank you to Andrew who pm me the coordinates of David who sales the oils seal fuel pump in the UK. He kindly sent me the correct seal in Belgium, but I don't know how many remains as he told me that someone bought him a full box. Do not use email to contact him as he has currently some problems with his computer. Here is the Phone/address of David http://homepage.ntlworld.com/carljdavies/Bearing%20Contacts.htm Bye, Guy Quote Link to post Share on other sites
badshead Posted January 9, 2010 Report Share Posted January 9, 2010 Thank you to Andrew who pm me the coordinates of David who sales the oils seal fuel pump in the UK. He kindly sent me the correct seal in Belgium, but I don't know how many remains as he told me that someone bought him a full box. Do not use email to contact him as he has currently some problems with his computer. Bye, Guy Guy, many thanks for the contact. Just to conclude this thread... Dave does indeed have a number of the original oil seals and retainers (only source left in the UK?). £1 per seal + 50p for the retainer. He also has the original AC rebuild kit which not only includes the diaphragm, valves, rubbers, seals, retainers and gaskets, but both springs, wire gauze filter, link lever, rocker pin and circlips - all for £15. He's a very helpful ex-Army bloke. He sends you the stuff in advance and you send him a cheque - not many people do business like that these days! Contact him by phone seems best - details here http://homepage.ntlworld.com/carljdavies/Bearing2.htm As you'll see he supplies other useful stuff as well. Quote Link to post Share on other sites
ts42673lo Posted January 16, 2010 Report Share Posted January 16, 2010 Hi there! THe ROadster Factory does sell fuel pump repair kits with the oil seal according to the catalogue description. I ordered one but the order has not arrived yet (waiting for the red loop pile carpet set) Cheers Alexandre Quote Link to post Share on other sites
Stev Posted August 23, 2021 Report Share Posted August 23, 2021 Hi, could someone please let me know where I can find this seal please! Thank you! Quote Link to post Share on other sites
Ian Vincent Posted August 23, 2021 Report Share Posted August 23, 2021 (edited) I bought an overhaul kit from someone in Australia and it included this seal. If you search the forum you should be able to find the name. Rgds Ian Update: I've just searched my computer and found I bought the repair kit from Wagga Wagga Spares. It cost AUS$ 39.40 plus $15.00 shipping in 2009. Further update: The repair kit I bought was made by Goss Vehicle Mechatronics (an Australian automotive parts supplier), and is part number 966VC - it is in their current catalogue so I guess it is still available. Attached is a screen dump from the relevant page from their website. Edited August 23, 2021 by Ian Vincent Quote Link to post Share on other sites

Alanretired Posted August 23, 2021 Report Share Posted August 23, 2021 Hi all. I have a similar request I have just fitted a new fuel pump to resolve an oil leak. The new pump has a two piece pressed and riveted steel foot which looks very cam unfriendly. The removed pump had a bronze (or similar material) foot which I would like to refit if I can obtain an oil seal. Can anyone please advise where I could buy one. I could then carry the new one as a spare. Regards Alan Quote Link to post Share on other sites
rcreweread Posted August 23, 2021 Report Share Posted August 23, 2021 Stev/Alan - there has been some comment in the past that this seal might be available from TRF in America, but I don't know if thats still the case. The only way I'm aware of to get this seal here in the UK is to secure a Dave Davies rebuilt pump, as he has a small stock of these seals which he uses in his own rebuilds - he does not sell them separately. If you have an original AC Delco pump, then he can restore this for you - if you haven't got his contact details, PM me and I will send them to you. If you don't want to go down this route, then I have some of his rebuilt pumps spare so again PM me Cheers Rich Quote Link to post Share on other sites
