Fuel pump

Anyone know what the PSI is on a 91 manche fuel pump ? Also is it a GM 0-90 ohm sending unit?

Thanks

I would also be worried about how much volume the pump could put out. Might be able to keep up with the demand of 6 reg injectors, but might fall behind trying to supply 8 thirsty v-8 injectors.

if you give me the application the ls1 is for i can look it up at work. off the top of my head its probably 50 or 60 psi though.

Yea i got the answer i didnt want lastnight at the dealer... 60 psi for the LS1 at the least. So now i have on order a 255lph 60 PSI pump from lightning motor sports.
