Hello, im doing a 98 LS1 into a 69 bird and i bought a sumped tank from rock valley- a stock repo tank not the stainless one and it came with a pump marked as TPI ? tpi according to me spec for tpi is 40-47 and then according to my info the LS1 requires 55-60psi - will the TPI put out enough for the LS1? i know the regulator adjusts this , but i dont want to be chasing a problem later cause i didnt bother to ask this now- Rock Valley says this is the right pump - just thought id ask some of you "Experienced" people who have been here done this :wow: cant wait to fire this up!
ALSO any suggestions on the rest of the system- pressure to late vette filter regulator and a single line to the front? or run a pressure and return line from the front? - open for suggestions

I bought a stainless tank from them for my LS1 and it came with the same sticker. I called and they assured me it had the correct pump. I believe they called the pump a walbro 304.
