1963/1964 Fuel Pump PSI and Fuel Line Size
I have a 1963-1965 289 HiPo motor with a Autolite 4100 600cfm carb fit into a 1966 Sunbeam Tiger. Estimated HP 271-306.
The stock 260/289 fuel lines were 5/16" and ran a SU AUF301/303 points fuel pump moving 15GPH at 2 psi max but only supported around 200hp.
I need to know how much fuel pressure and GPH I should need.
I am planning to increase fuel line size to 3/8" and would like to secure a SU Electronic pump to maintain the original look.
Thanks in advance.
