Re: FUEL PUMP PULSATOR

It quiets the noise from the pump a little bit. It also restricts some of its output. Removing it is the best thing to do.

Re: FUEL PUMP PULSATOR

When I put my Walbro 255 in the car would jerk a little. I pulled the tank back out and removed the pulsator. I replaced it with a peice of fuel injection hose and my car ran perfect. That was 5 years ago. I dropped my tank last year to replace the sending unit(to fix guage) and the hose was still working perfectly.
