There are usually some up for sale when high spec cars get broken, check out Speedline imports threads as he might have a few up for grabs, get the best you can afford, its fueling, do not buy cheap, buy cheap you buy twice, which is usually ok with most other components, I would rather the FPR to be 100% perfect all the time, so ive got an Aeromotive FPR with aeroquip fittings:

you dont need one unless your changing you need more fuel than what you currently have.

i dont have one and have run up to 20psi of boost on stock twins.

Id only fit one if i was running aftermarket rails and massive injectors

As far as I\'m aware, the stock FPR cannot cope with the flow from a lot of uprated pumps, so can be problematic when trying to consistently control the fuelling when you up the supply. Lots of people seem to have reported this.

I currently have a Walbro 255LPH running on my FC with the stock FPR, as expected its overfueling a lot, due to the fact that the pump is running faster due to having less resistance, but the OEM FPR can\'t regulate the extra flow, so am getting the Aeromotive FPR fitted beginning of next month, its running so rich it hurts your eyes lol
