Hi all. I know there is a lot of information on here already about the subject but I'm afraid I haven't been able to find the right information for my specific set up by searching previous threads. I'll be putting a GT cam in my mk2 in a couple of weeks and want to make sure I've got all the parts ready before I start. I'm confident that I can do the cam swap with my previous experience and the guide in faq. What I'm still stuck with is the fuel pump. Most of the info on here relates to what to use if you're running bike carbs, but I've got a weber carb (28/32 iirc) and don't know what pressure I need. I've spoken to a friend who says the pressure on facet pumps is adjustable but from what I've seen this isn't the case. I've also looked at the specs of the standard mech pump which says at 1000rpm it pumps at.0.20 - 0.25 bar. Which is a useful starting point but this presumably increases with revs. I've also read about using a ways of dealing with excess fuel, my carb definitely has a fuel in pipe and a second pipe that returns fuel to the tank. I have always referred to this second one as fuel return. Does this mean that I can have a set pressure fuel pump which may pump too much but any unused fuel will be returned to the tank anyway? If that's the case what bar / psi facet pump should I be looking for? Links would be appreciated. (all these questions and I haven't even got to the inertia switch yet) 😣
Hi everyone. I think my fuel pump is dead. At first I thought I'd ran out of fuel so put 2 Jerry cans in but still won't start. You here the pump prime when turn the ignition on but if disconnect the hose at the the inlet only get fuel if you suck it I don't recommend this! I know I can't get a new like for like so will need to use a universal. Any suggestions or advice would be a great help please. Thanks guys.
Hi Does anyone know the part number or where to get the o-ring that seals the mechanical cam driven fuel pump. It sits over number 4 plug and is leaking onto it. I ordered one 052127311 and it is too large if indeed the correct one was in the packet. The one sent is the largest at about 45mm OD I am after the smaller one please. Luke
Hello everyone! I'm having some mysterious issues with my car after the swap. I swapped everything, it has the GTI fuel pump, but still has a rough idle when cold, and poor perfomance even when the engine is at it's operation temp, and it cranks for 3-4, even 5 secs before it starts the engine.It struggles at higher rpms, and has a top speed of 150 km/h instead of 200 km/h. I replaced almost every sensor I could, it's definitely not the lambda sensor, or the crankshadt pos. sensor. Even replaced the coolant temp sensor. I noticed that I have a grey 167 fuel pump relay with 4 legs instead of a black 410 with 8 legs. The guy who made the wiring, didn't notice the different relay. Can this be the cause of my problem? Or could the VVT actuator failure cause this? Thanks for the help!
