Looking into raptor fuel pump HELP!

Postby Tsbourne09 » Wed Aug 17, 2011 2:16 am

I am conaidering buying a raptor fuel pump. What are the gains of this pump and is it worth it? My pump is maxed and it seems like it may begin to run short of fuel at high rpms. Is it worth buying?

i know it is worth it if you have a tuned pump, cause it isnt good at all to run an injection pump lean, as for the other question, i have not installed one on mine either yet :? waiting for the funds,lol

Ive got the 2nd gen help on mine and it idles at 15psi and at WOT hits 17psi, can't pull it down....rebuilt the injection pump, no seals have blown yet. its a little more expensive, but you never have to worry about the pump quitting bc of an electrical problem
