Fuel pump?

what's a good replacement pump? stk is a 190lph is a 255lph to much? im not making crazy hp but just bolt on's and a hot cam. can i just get a pump or do i need the harness?

If you haven't changed the fuel system, bigger line, pickup, etc. And/or your not having pressure problems, why do you need a new pump? Check your fuel pressure at WOT under load.

The reason is the car has over 100k and just looking for an upgrade

The Racetronix pump is a cheap upgrade and is rated at 255lph. You can get them for around 125 bucks.

I am using a Walbro 255 pump. It requires minor adapting and emits a audible operating noise in my car.
