Fuel Line

[FX3FX3]

A simple question for most of you guys....
On the fuel line, right at the end before the connection fitting within the intake manifold fuel inj rail (1992 LT1) what the heck is that? looks like a diafram or is it a valve?

Pedro, did you ever figure it out? Is it the pressure regulator? :confused

pressure regulator

that is your pressure regulator,, dude, 100 percent sure, yes thats a diaframe,,,


i have it on my 1985,, all vetts should have one, ,i think,,


u can,, replace the dialphrams in those, for a small cost, i think,,

no

no the press regulator...keep going down towards the filter. That "thing" is between the FPR and the fuel filter

I seem to remember reading somewhere about a 'dampener" of some sort being used at one point in the fourth generation Corvette to quell excessive noise/vibration/rattles etc. due to the fuel pump pulses. If I can remember where I saw that, I'll post it here Pedro.
