the gn pump is in tank.. not inline.. my bad.. used wrong word
the computer controlled carb has a mechanical pump.. tbi isn't a carb
the tbi runs at 15-19psi..
the buick runs at 45-60psi
a carb 5-7psi..
the tbi pump didn't move much volume of fuel.. as the v6 tbi didn't need much..
the s.e.f.i. in the t-type and g.n. moved tons of fuel when compaired to a tbi pump..
if your goal is to run a carb on your olds, you'll need a return line and a fuel pressure regulator.. to use the tbi pump..
if you plan on efi down the road.. any multi port efi will need more psi than that tbi pump will put out..
note... a deadhead fuel regulator will kill any electric pump.. you must use a return style..
new cars don't have a return line because they use a regulator/bypass at the tank..
only thing that cools the pump is fuel flowing throw it..
