Hi all,

I am running a 1990 police 5.7 with the original TBI. I use a Carter P5001 pump attached to a cross member that is under and behind my gas tank. It uses a 100 micron pre and 10 micron post filter. This is just for back ground.

The pump has been running for about 5 years now and is starting to cut out. I do have a new spare, but before I change it I thought I would think about the issue I have. Mainly noise. I can hear the pump half a block away. I had been reading lately on using PWM fuel pump controllers to help with noise, heat, and longevity. Every application I have read up on was for higher pressure pumps. I am not sure this would benefit a TBI installation. Most controllers I have read up on require a returnless system too.

Has anyone here installed one and what was your results?

Thanks
