electric fuel pumps

[chris.S]

is anyone running one
and what are the pros and cons?

injection engines have them as standard - necessary for injection, high pressure, potential to leak, need for good inspection and maintenance when required, corrosion of fittings and decay of pipe now age related problem

carb engines don't need them, but often fitted by the lpg boys as easier to isolate electrically and save pumping fuel unnecessarily when running on gas so reducing fire risk

cons - noise, more electrics, something else to go wrong - important to ensure switches off as soon as engine does by ignition/stall so potentially greater fire hazard , expense

advantage - steady supply pressure/flow not determined by engine revs good if you run an worn old engine/carb at high revs, untill it/they die.

As above but more reliable than pattern parts and cheaper than original equipment pumps, only viable option for non available 2.0 ltr air cooled pumps. Fuel is delivered cooler which is denser, and easy to rig up as a immobiliser.

I am running one, but only because my V8 engine doesn't have the facility for a mechanical pump.

They do need to be wired to that fuel stops pumping when the engine is stopped. Mine lives under the van by the tank, so noise isn't an issue. As they're independent of engine speed, I suspect more of the fuel spends its time just being pumped round, but that's no bad thing as long as the pipes are in good order and not leaking.

I wouldn't bother with one if I didn't have to.
