And if it dont work I am going for a higher pressure pump..Is the walbro pump the same size as a stock pump?I mean on the outside to look at?Here is a pic of my car I am putting the ls1 engine in..

I had just test fitted an 00 F Body LS1/T56 into my 69 Elky, got the motor to go in with no real problems but it was gonna take MAJOR floor pan "butchery" to clear the T56 as the Chevelle trans tunnel is just "low". It was very doable but I didnt want to chop the car up that bad so now the "old school" LS6 454 BB is back in the Elky and Ive got the LS combo going into my 87 442 where it all fits much better! Its been "musical motors" around here all week! LOL! Bill

yup!
ive never deadheaded a pump, but i know of TPI guys that have jacked the pressure way over 80.....
i also wouldnt recommend it for a modded motor... not enough volume.. but its fine for a stocker.. especially if you already have it in the tank.
its not like its a magic pump that knows what its fueling... its basicly the same design as the stock LS1 pump, only a little smaller internally because it was designed to move less volume. its design is fine with the higher pressure of a LS1 system.
a TPI pump on an LS1?? the TPI pump has half the flow rate of an LT1.. and the LS1 is higher than that... why waste time with a stock TPI pump (which barely pumps enough) when you can pick up a stock LT1 pump for 50$(they work on TPI as well) or LS1 pump for 65$... or a walbro for 90$...

its not ideal.
its not something i would swap into there.
but if its already there, thats fine.
