If you are running a S10 in tank pump for a carbed S10 you may not have enough volume. If you running a S10 fuel injected in tank pump you probable have enough volume but too much fuel pressure and would need to run a fuel regulator. The good regulators have a fuel return line and are adjustable. I'm running a S10 V-6 in tank fuel pump with an adjustable regulator on a 400 hp carbed SBC. I can maintain 4 psi all the time.
