This piece I am told is a pulse dampener? It was attached to the fuel line that connected to the fuel rail. The plastic connector was cracked and leaking. When I removed it, it broke off completely. How do I repair? thanks.........

The easy way it out take the fuel line that was connected to the metal tube on that damper and connect it directly to the tube end on the fuel rail.

That damper extension/female out line can be repalced with the proper tools but it's not needed.

Are you saying eliminate the damper?

Are you saying eliminate the damper? Yes.

Stockman - send me the broken one and I'll see if I can replace that end and tube.

Yes.

mike thank you I sent it off to Dave Schmitt in KY. Can you run the motor properly without the dampener? Yes. BTW - it's the engine runs, while we use the [starter] motor to get it running.

I took the original fuel damper off my red 84 SVO at about 2000 miles. It then lived in a box somewhere for the next ~25+ years until I sold it (well, more accurately "donated" as I was never paid for it!) to someone doing an 84 restoration.

It must have a function? It is specifically to dampen the hydraulic [pounding] noise in in the fuel lines. Not so much a problem with nylon tubes, more of an issue with the steel tubes though. And with the nylon it's more of an issue in very cold weather; not so much in Southern Arizona.

And it's much less of an issue (the hydraulic pressure surges) in SFI fuel injection systems versus he batch-fire system used in the early turbo EECs.

They also installed vibration damping weights on the back of he gearbox and front of the rear diff. Which most people take off.
