  • Recommended eletric fuel pumps

    Something I just did and also a common question these days as the original AC pumps fail and the aftermarket ones cause havoc to control.

    My own presonal prefernece is a Carter inline rotary pump, proven by thousands of miles for me on VW based cars (real pre-80s VW's not new junk) .

    Nice, quiet and just works.

    First to fit it I use a 1/8 NPT to 8mm right angled connection to exit the tank, this removes the 1/8 7/16 transition fitting to make space.

    Second the fuel pump, the pump body is isolated so will do + or - earth.

    In addition the pump needs safety interlocks so the pump cannot run when the engine is not running (link to oil pressure sender) and of course a inertia cutout switch in case of a bump.

    I will stick a diagram up for this later

    If it can be fixed with a hammer, I am your man

    My preference is SU pumps . you can fit these either in the engine bay or by the tank . Engine end ones are known as LP ( low pressure ) , tank end are HP ( High pressure )
    I use and engine end in one car and a tank end in tother .
    Tank end are hardest to fit but neater , engine end easy to fit but dont look as neat . As above you need to wire in a inertia cut off and a manual switch .
    I use AUA66 for the engine end and AUF214 for the tank end , neither require a regulator , you can get the old points based ones or electronic ones ( state positive or negative earth as these are polarity specific - points based ones dont care and will run on either
    Tank end
