hi dave they are designed to pull at 4psi you can set a spare push pump next to the tank it also pushes through the su regards jim

Before going off at the fuel pump I would be tempted to ascertain what condition the fuel pipes between the pump and the tank are in. Are ther clogged? Is the gauze on the end of the pick up in the tank still in position and unclogged? Are all the joints still dry? a wet joint will show that the pump may be sucking a small amount of air as well as petrol and as a result not delivering enough fuel.
Once all these points have been checked - perhaps you could even try manually sucking fuel through the pipe system- then and only then would I be looking at the pump.
A blockage after the pump between the pump and the carburettor could possibly have the same effect of limiting fuel flow.
If this is the first time the vehicle has run since October I would also be suspicious of the condition of any fuel that has been left lying around in the system. Modern day fuel, if left for a long period of time will evaporate and leave a shellac like substance in its place which is often enough to restrict any future flow through the affected area.
In answer to the original question, the answer is 12 volt but take into account the polarity of the battery when ordering, as a positive earth pump will not function on a negative earth system, nor vice versa.

used our primer at work. got it to prime and put it on. it ran fine. was idling fine withuot me in it.

but after a while it died. lol i think the fuel pump goes cactus once its warms up. the pump felt warm too. i should proably just try and rebuild it and get a low pressure pump on ebay.

in an ideal world yes because it means the essentially self prime if you get a vapour lock or run out of fuel.. (well they dont have to work so hard anyway

the pumps are better at the push side than the draw side.
