dpb Posted July 22, 2015 Report Share Posted July 22, 2015 Finally started taking the head off to find cause of my overheating problems. (head gasket or cracked blocked). My Haynes manual says to shut off the main fuel line tap, on the line as it enters the engine bay. There isn't one on mine, been replaced by some shielded rubber pipe I'm guessing, but it seems like a good idea. Did they have one originally? Do people still have them?

peejay4A Posted July 22, 2015 Report Share Posted July 22, 2015 I don't think the 4/4A had a tap fitted. Mine didn't but it has now. From Demon Tweeks iirc. Quote Link to post Share on other sites
stuart Posted July 22, 2015 Report Share Posted July 22, 2015 They didnt have one originally, it was deleted after 3a production IIRC. Stuart. Quote Link to post Share on other sites
BlueTR3A-5EKT Posted July 22, 2015 Report Share Posted July 22, 2015 My experience is they are fine if you do not touch them (Original Ewerts fuel tap on TR2-3A) Once you use them, after a long time of being static, they leak and require maintenance which involves shutting off the fuel supply from the tank......

dpb Posted July 22, 2015 Author Report Share Posted July 22, 2015 Thanks. I think I might put one in. Dave === Quote Link to post Share on other sites
Fireman049 Posted July 22, 2015 Report Share Posted July 22, 2015 Hi Dave ~ Don't fit the original 3/3A fuel tap as they are useless! I fitted one which I got from Vehicle Wiring Products. It's an in-line turn tap one and very efficient. Tom. Quote Link to post Share on other sites
Lebro Posted July 22, 2015 Report Share Posted July 22, 2015 The original 2/3/3A tap can be made to work well, just ditch the cork seal, & replace with a short section of rubber fuel pipe (you have to choose the right diameter of course) I did this in 2013, & it still works well, & does not leak.

iain Posted July 22, 2015 Report Share Posted July 22, 2015 Bob,Thanks for that tip must see if I can make mine work! Iain Quote Link to post Share on other sites
Richardtr3a Posted July 22, 2015 Report Share Posted July 22, 2015 Too late for me Bob. I soldered mine open a very long time age and it has never leaked. But I am looking for some anti theft precautions. Richard & H Quote Link to post Share on other sites
BlueTR3A-5EKT Posted July 22, 2015 Report Share Posted July 22, 2015 (edited) Pete & Tom, did you use this sort of thing? http://www.adrenalin-pedstop.co.uk/p-Inline_fuel_tap_fuel_cock_8mm_connections-6268.aspx?gclid=CLmT_ern7sYCFWQTwwod9tQKBg Peter W Bob, I like the idea of a piece of rubber hose as a replacement for the cork. I just do not touch the tap on my car unless it is critical. Edited July 22, 2015 by BlueTR3A-5EKT Quote Link to post Share on other sites
Fireman049 Posted July 22, 2015 Report Share Posted July 22, 2015 Hi Peter W ~ Mine works on a similar principle but the tap is much longer. I wish I had seen this one before because it would suit my requirements better. Tom. Quote Link to post Share on other sites
ianc Posted July 22, 2015 Report Share Posted July 22, 2015 Deletion of the cut-off valve was one of Triumph's stupid cost-saving measures. With the tank holding about 12 gallons (more in my case) and sitting above the rear axle it is very difficult (unless the tank is nearly empty) to stop the flow if one disconnects at the fuel pump, so installation of a cut-off valve is very sensible.

PaulAnderson Posted July 22, 2015 Report Share Posted July 22, 2015 I believe that Revington TR used to make a flexible braided stainless pipe with an inline tap. Nice but not cheap if I recall. Paul Quote Link to post Share on other sites
ianc Posted July 23, 2015 Report Share Posted July 23, 2015 Paul, I didn't like to mention it (I get accused of advertising), but that's what's on my TR4! Ian Cornish Quote Link to post Share on other sites
AlfredHitchcock Posted July 23, 2015 Report Share Posted July 23, 2015 I thought it would be a good idea to plumb in a 2 way valve/tap in the flexi hose from the bottom of the tank enabling you to either cut off the fuel or drain it off. Cant find a suitable one though. Quote Link to post Share on other sites

I like that one, Peter. Compact and metal. I keep a pair of these in my TRs toolkit. Simple enough to clamp the fuel line leading into the pump in case I need to dig into it, and they have other uses too. These are cheap and available from many sources. Edited July 23, 2015 by Don H.

peejay4A Posted July 23, 2015 Report Share Posted July 23, 2015 I think this is the one I used, with the appropriate push on unions. http://www.demon-tweeks.co.uk/motorsport/fuel-line-taps/fse-high-flow-fuel-cut-off-tap Quote Link to post Share on other sites
