looking at buying 255lph pump.

Anyone know a good place to get one? it for a 1995 camaro,

Try the Racetronix pump from Thunder Racing. It'll run around a 140 bucks.

anyone use the holley 255lph pump, what all do you have to do to the sending unit to use a 255 pump?

I'm not sure about the Holley pump. The Racetronix pump is a direct drop in, you won't have to do anything to the sending unit.

By far the best place, wouldnt go anywhere else. Installed mine, worked fine. If you in TX you could get it $100.00 cash no tax or anything! Great to deal with.

do you have to change your regulator or anything with the walbro pump form autoperformanceengineering.com.

The stock regulator should do the job fine in keeping the pressure to spec.
