Can you put a fuel pump for a 4.3 v6 in 5.7 v8?

fuel pump for v6 will not supply enough fuel for a v8. they are

calibrated to supply different amounts of fuel at different

pressure

It depends on the year and fuel system. I know better. I have

been with Gm for 22 years. I have a v6 4.3 fuel pump out of a 90

s15 in my 89 silverado with the 5.7 350 v8 and its just fine, look

it up, its the same part number. it even fits a 7.4 chevy and a 5.0

and a 2.5
