salmon Posted October 9, 2006 Report Share Posted October 9, 2006 Has anyone else had a problem with thier fuel pump being really noisy? Currently a really loud buzzing all the time. Fuel pump has been replaced in the last few years, and works fine, any ideas how long they last, or if anything else could be causing this? Cheers Quote Link to post Share on other sites
badshead Posted October 10, 2006 Report Share Posted October 10, 2006 (edited) Has anyone else had a problem with thier fuel pump being really noisy? Currently a really loud buzzing all the time. Fuel pump has been replaced in the last few years, and works fine, any ideas how long they last, or if anything else could be causing this? Cheers Is yours a Lucas or Bosch pump? Excessive noise could mean the pump is not getting enough fuel or is restricted (clogged filter?), pressure too high (PRV?) or maybe it's just knackered, but I'd expect to get more than a couple of years from a Bosch pump. I'd start by checking you've got a good gravity feed from the petrol tank to the pump, replace any pre and/or post pump filters and check fuel pressure at the metering unit. Also check fuel return back to the tank (remove petrol cap and you should be able to hear/see fuel returning. If all checks out and it's still noisy after that, change the pump.

Not sure what kind of pump it is tbh, think checking the fuel filter etc sounds like a good idea as a first stop, then look at the other things. Quote Link to post Share on other sites
Rob Salisbury Posted October 10, 2006 Report Share Posted October 10, 2006 Easy to tell the diff. ......the Lucas looks like a wiper motor with a brass blob attached, the Bosch looks like a proper flow through pump and works like one too........ though it does get noisy after some time, when it does throw it away and get another one!!

Been told to measure pressure at metering unit, but easier said than done. 110 psi guages for measuring fuel pressure arenty readily available. Any clues Quote Link to post Share on other sites
raydrink Posted October 10, 2006 Report Share Posted October 10, 2006 (edited) Hi Salmon, If you find it is a Bosch pump then the following thread might be of interest to you. I found that by replacing the poorly-specc'd pre-pump filter to my Bosch pump, it made all the difference. http://www.tr-register.co.uk/forums/index.php?showtopic=7360 Please read the thread from start to finish because it takes you on a wondrous journey. At the end of the day, do not use the Pro Flow filter. regards Ray Edited October 10, 2006 by raydrink Quote Link to post Share on other sites

Any clues Robin It's very easy to source all the components you need for about £40 - try: Hydrotechnic . When buying the 3/8 BSP T adaptor and hose, I'd recommend paying a bit extra and getting the 'Minimess' system (also available from RS Components and Pirtek). It allows you to keep the T adaptor permanently in-line and connect/disconnent the gauge with ease - no spanners or fuel spill. It also uses a microbore hose so also gives you the option of routing into the car if you wish to test on the go. Before buying your own, worth checking with your local group - someone might be able to lend you one. If you live near Bristol you're welcome to borrow mine. Quote Link to post Share on other sites

Just frustrating as I expect toi end up having to replace pum with Bosch and looks like its a £300 investment, ouch ! Quote Link to post Share on other sites
salmon Posted January 31, 2007 Author Report Share Posted January 31, 2007 Finally got round to having a look at the noisy fuel pump. Ordered a new filter etc, however after having a look at the fuel pump, doesn't look like whats its supposed to? Has the original one been replaced for this , which is why its so noisy, any advice appreciated. Cheers http://i75.photobucket.com/albums/i314/sal...79/DSC00121.jpg Quote Link to post Share on other sites

Cheers http://i75.photobucket.com/albums/i314/sal...79/DSC00121.jpg Hi, It's definately not a Lucas pump. Looks a bit of a bodge job, wrong wiring etc.. I don't like the idea of the jubilee clip, especially with the pressure involved. the Lucas pump is prone to being noisy. If you can get to the Triumph Spares Day at Stoneleigh, Warks on Sunday 11th. February you should pick up a second hand one for use or suitable for reconditioning. Lots of the TR specialists there as well, pick up a new one.

Bit of a trek down to spares day, but will just have to keep my eyes open see if anything comes up. Either that or start saving my pennies for a bosch one, or buy a noisier exhaust to drown out the noise! Cheers Quote Link to post Share on other sites
millsie Posted February 2, 2007 Report Share Posted February 2, 2007 Hi - looks like one of the Sytec pumps (pic and reference material here http://www.fuelsystem.co.uk/injection.htm) - the popular Bosch pump is the 0580 254 909 on the same site for £90. I've just ordered an adapter which should connect the Bosch outlet directly to the existing original high pressure pipe to PRV - once I've checked it's the right one I'll post details.

Thanks, Dave Yep, looks exactly like that one. Have won a lucas one for £30 off ebay, so was going to try and fit that one, which should be a bit quieter. Would be interested to see if the bosch one is any good so might wait to see before I fit the lucas. Quote Link to post Share on other sites
