TPI Fuel pressure

[cgpastor]

How much fuel pressure do I need for a 91 TPI motor? Also can I use an inline fuel pump?

Motor is from a corvette, are they any different than the camaro 5.7 TPI?

tpi fuel injection swappers guide says 43.5 lbs is what most injectors are flow rated at. Changing this more than 15% will require ecm calibration and will shorten the life of the injectors...

im using an intank pump normally used in typhoons and syclones, which is rated at about 90 psi. it will fit in your tank sending unit in place of the weaker tbi pump. your pressure regulator which is located on the fuel rail, should only let the injectors see approx 45psi as Primed92 mentioned. youll be ok with anything more than that.

as for the vette motor, i know theres quite a few differences: two i can think of are they have different accessories and the vettes had aluminum heads.
