hey i just got the mallory 4309 fuel pressure regulator and when i recieved it there was this little metal like spacer piece so to say... and the sheet of paper said to take off nut take out spring and plunger discard spring and put this metal pin deal in instead and reinstall plunger and nut.... are they talking about for the electro fuel pumps or the regulator itself... i'm confues cause the picture shows a fuel pump but i ordered the regulator and it came with that... ??? also why is it that when i screw in a 3/8 thread into it goes good half way then gets hard like its startin to cross thread.... and one more... what vaccum line am i suppose to hook the vaccum port up too ?? or do i just plug it... need help quick.... cars all tore apart waitin for me ... thx

it is only for the fuel pump, do not put it in the regulator!!!!!! you just plug the vacume port

I had to read the instructions 5 times before I realized it went in the pump not the regulator

So far I am unhappy with it, the fuel pressure keeps moving around and no matter how many times I reset it it changes. I have posted about this before. I am wondering if the problem is with the stock TBI pump. Some other board members said they have had the same problem. Anyone else know?

ya... the tbi stock pump just doesn't wanna keep with a constant pumping action... does anyone know if this can be fixed somehow or does it require a new pump??
