welshpug posted a topic in XU Engine & Gearbox Service and Maintenance - ARCHIVEThought I'd post up how I did this earlier, Sinbad on here needed a replacement fuel pressure regulator and I wanted to be sure that the one I had spare was working properly. so, what do you need? well I used a Trackpump Fit valve head onto fuel rail inlet (Presta size fits nicely) you would need to remove the hose from the fitting to do this so if they are original hoses (hard plastic, coated with rubber) then it would be advisable to get another union or some method to fix the hose to the rail. then pump away! It wont take long with a decent pump like this SKS Renncompressor to reach the 3 bar break pressure that the most common GTI's use, some apparently have a 2.5 bar item, I remember a Peugeot Talbot sport mod was to pop a 3.5 bar item on. as you can just about see, the gauge went to just over 3.0 bar and the regulator squeaked the excess air out, just to make sure it didn't leak I left the pressure on the rail to ensure it didn't leak. Ten minutes later it was still as I left it, so all good! job done. obviously this wont test whether your fuel pump is still up to it, or that the one way valve in the pump is working, but still an easy check to do as everyone should have a pump of some kind to hand.
Hi everyone! Here he comes, typical lurker not contributing until he's a question to ask.... Since my car has been in for a service with Peugeot (long story as to why it ended up at a main dealer), I've noticed the engine idle is higher than usual, bot hot and cold. So, decided to have a look at the weekend, and noticed the little rubber cap was missing from what I think is a diagnostic/test port on the inlet manifold? Hopefully picture attaches to show it. Anyway, if I cover the hole, the idle speed reduces, and stabilises, to what sounds like its original pre-service speed. Does anyone have one of these little rubber caps knocking around, or should I just try to tape it up and see how I get on? Thanks in advance! Mark F
