Default Electrickery fuel pumps...

hey all..

my studes electric fuel pump , has shown signs of imminent failure.

went shopping for a replacement . picked up a 4-6psi 96gph , which just stopped working around 3 mins after starting the car.. needless to say i was a bit unhappy - id spent 1.5hrs tidying up someones mess as the same time..

im wondering what you guys use in the way of electric fuel pumps? recommend them or prefer mechanical?

keen to hear all thoughts / suggestions ..

thanks 'crate

ps the original 259 mech pump was in place when i got the car , but i suspect had blown a diaphram due to oil blasting out of the breather hole.

ive replaced mech pump with a SBC blanking plate - nice fit too..

Crate, I like the little Facett pumps. They come in several different pressures and hose sizes. Mr Gasket and Purolater both also have a version of them, too.

I use mechanical pumps on all my Hot Rods. Haven’t had a failure in many years

Mechanical on mine too but have run electrics. both usually work well for long periods. Have you proven everything else good? The first pump was failing and the replacement went out. Could there be a blocked fuel line or something electrical that's killing pumps?

slowly been working all the bugs with car ,, the mech pump was a repro part . ive since found out there was a batch of faulty ones that had an oil seal put in backwards as a result oil leaks out the diaphram breather hole. strip and assemble has proven i cant solve it.
the electric replacement just isnt sucking the fuel up , and should be close to the gas tank not the engine room where it is .. ( this one has fueled the car inb the 6motnths ive had it)
wiring is good ..
sigh

Holley blue, no more than 24" from the tank, with regulator and return line to the tank. Set to 6 to 7 psi.
If you don't run a return line, the pump will dead head and fail.

I run elec pumps for 2 reasons. They can be used as a theft deterrent & I like to route my gas lines from the firewall instead of the front of the engine! Never had one fail!

Generally speaking, electric pumps push better than they pull... ideally, the pump should be close to the tank and "wet" by gravity...

The Holley Red version does not need a return line. I have one in my Rambler.
