    I aim to convert the fuel pump on my Somerset from the original mechanical one to a s.U. electric pump.

    Does anyone know whether it would be best to mount a push or pull pump and would I need to fit a pressure regulator?

    With kind regards


    I have an SU type pump fitted to my Somerset because i have a 1959 Riley engine in it which does not have provision for a mechanical lift pump.
    Mine is mounted to the NS Bulkhead and appears to be OK.
    If the location was good enough for a Morris Minor i should think its good enough for a Somerset.

    If the pump is pushing the fuel will be under pressure. if it pulls it will be under a negative pressure which means the fuel can vapour lock at a lower temp but as the fuel line under vacumn will be in cold air i don’t think it will be a problem for you.
    The only reason i had an issue is because the Riley 1500 exhaust manifold runs close the metal fuel line which caused it to vapour lock so i had to put a heat shield in place. all ok now
