electric fuel pump

[bluefoxamazone]

hello,

just installed an electic pump. It doesn't seem to move a lot of gas... is the position, horizontal or vertical or somewhere in between important? Are these small inline pumps self priming? thanks!

ford inertia switch from local junk yard. i do not have the mechanical pump at all. the switch has a idiot light that would illuminate on the dash if said switch tripped. i am going to put a small light under the dash hooked to that wire that will let me know if it trips.

Where did you mount the pump? Electric fuel pumps don't typically draw fuel long distances. Hey are better at pushing it. Mount it near the tank so that gravity flow will feed it.

determine what is or is not sufficient...5-6 ounces in 15 pump strokes with original pre-primed fuel pump...have you done a volume test? have you run out of gas during WOT performance?  As stated..pushers not pullers...and ensure you are not sucking air on the inlet...

The pump is mounted right behind the tank. I think i might have suffered from a trapped air bubble somewhere. I will look again tonight and try to mount the pump horizontal. I will also drive the car for a while with this pump "off", I guess that the mechanical pump will fill the line and air entrapment wil be gone.

grtz,

Navyboy, I am about to mount new fuel lines and electric pump and am wondering where you mounted your pump.  any way you could post a picture of the placement?  I am having trouble finding a good spot to mount it besides infront of the rear axle.  I just cant find a good place that it will push fuel well.  Also, if anyone else has a picture of their pump placement it would be greatly appreciated!

Mine is mounted just in front of the rear axle on the inside frame rail with a filter between the pump and the tank. It's close enough to the tank to push. I also have a filter just before the split in the fuel line for my dual carbs. No pics though.

Mine is mounted similar to Deathbounds: mounted about two feet from and below the bottom line of the tank, a filter before the pump and a second just before the carburator. I had not started my truck for at least a week, today I turned on the key, let the pump run for about 6 seconds and the engine started without any assistance from the choke, the foot pedal, or anything else, just started on low idle, I will never return to a mechanical pump!

Mine is mounted on my 48 directly below the drivers seat on the frame rail facing out to the road ,same place on my 41 .Both work fine

Since some of the electrics are used as auxiliary pumps and not always on, how do you determine if it will allow the mechanical to pull fuel thru it? It was mentioned some do not do this.
