quattro Posted August 22, 2017 Share Posted August 22, 2017 (edited) This may sound a daft question, but I don't know the answer so thought I should ask Can I just remove the fuel temperature sender, and screw in a fuel pressure sender instead? If so, does anyone know what the thread size is? Richard Edited August 22, 2017 by quattro Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted August 22, 2017 Share Posted August 22, 2017 Nope, that hole is blank. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted August 22, 2017 Share Posted August 22, 2017 I'm guessing that you may be able to drill a hole in the bottom of the blanked section...? Early P38 version have a Schrader valve on the opposite side. No idea on the thread, sorry. Quote Link to comment Share on other sites More sharing options...

Yes, I have the schrader valve, not quite sure how I would connect that up though. What's the usual way of installing a fuel pressure gauge?

Bowie69 Posted August 22, 2017 Share Posted August 22, 2017 I just did a quick google, a schrader valve is 1/8 NPT so it appears the world is your oyster when it comes to fitting a FPG to that! Not sure what gauge you were thinking of using, but I suspect a female 1/8 NPT to 1/8 NPT adapter will sort you out. Quote Link to comment Share on other sites More sharing options...

Brilliant, thanks Bowie I'll give that go Cheers Richard Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted August 23, 2017 Share Posted August 23, 2017 Also spotted this, seems the schrader valve unscrews from the rail: https://discoweb.org/showthread.php?t=61690 Easier again? Quote Link to comment Share on other sites More sharing options...

Sure was - cheers for that Got one of these with two female 1/8 npt, and one male 1/8 npt threads. Got it fitted in just the right place and screwed in a pressure sender Refitted the valve, and a bit of wiring later, just need to refit the gauge pod and dash. And yes, it works Richard Edited September 8, 2017 by quattro Quote Link to comment Share on other sites More sharing options...

quattro Posted September 9, 2017 Author Share Posted September 9, 2017 I do like to complete threads Nothing worse than searching on a forum for an answer to a problem, then reading four pages of thread, to get to the end of it and still not find out if it worked Finished it off this morning and have been driving around Thanks for the help Quote Link to comment Share on other sites More sharing options...
