I have a RB25DET with PFC, GT30R, 040 fuel pump, 740cc injectors, stock fuel regulator.
my fuel pump is very noisy. it was brand new. its actually the 3RD brand new 040 i have had fitted to the vehicle and all have been very noisy.
it has been confirmed that the pump has been installed correctly.
when squeezing the fuel lines connecting to the stock fuel reg, the whingy pump goes quite, but after u release the lines, it goes noisy again.
the car coughs and splutters with anything more than half throttle, or pretty with any positive boost pressure.
i have looked and cant find any kinks in any fuel lines or anything like that, could there be an issue with the stock fuel regulator?
I have come to the conclusion that 040 fuel pumps cant possibly be so bad that 3 brand new ones can fail, so i am refusing to believe there is a fuel pump problem.
any thoughts?
cheers.
