Hey guys, well, I have a M42 engine and I think I have a lil' problem with it.. I met 2 or 3 guys who had the same car and their were doing like 700km with a gas tank... and with mine, I only run like, 350km MAX with it.. I change my O2 sensor, my gas filter.. and I just don't understand what would it be, I figured out that is was surely because this engine is a swap at the first time, so I have a gas regulator.. so, maybe that's that regulator that its not the right one or something like that ? ..

Here some pics of my engine for you to understand about the regulator I'm talking

Thanks guys, if you have the answer, it will helps me a LOT !!

it does look like an adjustable. bout the only way to see whats going on is to do a fuel pressure test.

Well, the regulator adjustable is at the max I can go.. So I figured out that this one wasn't the one I needed, but thanks for the advice, and about the fuel pressure test, can I make it myself ?

You need the gauge, suitable rubber hose and a 't' piece (brass). Once it is connected in then you can adjust and see the results. Remove after you have got it right. Hope you have the tools ok.

heres your problem. its not adjusted correctly. in order to properly set them you need to have a fuel pressure gauge installed so you can see where you sit. you can pick up a kit from a local parts store, but youll need to add in a t fitting to make it work
