Instead of a piece of rubber hose, Theres a Slip on connector block, from the Pump to the sending unit. Slid off with little effort. I didnt Like it, so i but a Piece of Fuel Injection hose on the new Bosch pump to the Sending unit with Fuel injection clamps. What is that block piece? a Fuel dampener of some sort? Should i put it back on instead of the rubber line? asking before i put it all back together. Thanks, Nick

 

pump pulse dampener, throw it away and install a hose and clamps

Thanks so much! I appreciate the quick response! I've done a about 100 GM Fuel pumps and ive never ran into one of these. Having it removed wont kill a Fuel pressure regulator will it? I'll find out i guess I've never had an issue with a FPR on the 90's GM's. Thanks again

 

The purpose of it is to help dampen the sound of the fuel pump going through the steel lines causing noise. Well you know what the problems are it is a common area for a leak and loss in fuel pressure.

 

Yup, mint deal. Test drove it. Feels good, no leaks. No gas smell (probably immune to for right now) all set to go 100K again. yay im glad thats done and over with. Somebody replaced the pump before with a Carter pump. Oh brother its no wonder!!!!!!! haha Thanks Man!
