6 Volt Electric Fuel Pump Recommendations?

[Jeff Balazs]

Hi Guy's;

I'd like to fit an electric fuel pump as a emergency back up for the fuel supply on my truck.

Can anyone recommend a specific brand & model that they have had good service from?

 

Thanks, Jeff

I got my electric fuel pump from MAC's. I don't recall the manufacturer, but I believe this is the link to it. http://macsautoparts.com/model-a-ford-electric-fuel-pump-6-volt-4-6-5-lbs-pressure-efp-9350-6/camid/MDA/cp/JS0R3CHL1137085/ Mine has a metal filter that screws into the inlet end. The one shown in this link has a plastic inline filter. Either would work.

 

I mounted mine just in front of the fuel tank and it is inline with the mechanical pump. I have it wired through a switch and I use it to help prime the carburator after long periods of sitting. I've also found it to be usefull at times when my mechanical pumps gets too hot, such as on really hot days, or from extended idling. I've found that in these conditions I get a fuel starvation problem at higher RPM's, probably because I don't have a heat shield over the pump. When this happens I flip the switch for the electric pump and the problem goes away.

 

I believe I have a picture of my pump installed in my Photobucket account, but our new firewall here at work won't let me access it.

Jeff,

I've got one.

 

AC.

 

PM me if interested.

Merle;

Thank you. Would you consider this to be an adequate full time pump if needed ? Would a pressure regulator be a good idea as part of this installation?

Thanks ; Jeff

[Merle Coggins]

I don't see why you couldn't use it full time. I originally got a lower pressure rated pump (2-4psi if I recall) and that's what I currently have installed. I've found that it can't quite pump through the mechanical pump unless it's already pumping. I got the 4-6 psi pump now, but I haven't changed it out yet. My other thought was to add a bypass line with a check valve and plumb it in around the mechanical pump to help with prefiling the carb, or as a full backup if my mechanical pump fails. I have full confidence in my mechanical pump, which I rebuilt with a kit from Antique Auto Parts Cellar, but I like the piece of mind since my last one failed me when the pin walked out. If I had the electric back then, with a good bypass system in place, I could have just hit the switch and drove home on the backup system.

Merle;

Again thanks for responding. This pretty much covers what I am thinking about. I really like the idea of flipping a switch and having a back up. Stalling or breaking down in traffic here is a recipe for disaster. It is especially unacceptable if there is a way to eliminate or minimize some of the possible causes.

 

I suppose it is the old boy scout, desert rider and boater in me....... but I like to be prepared to cope with these sorts of potential situations as gracefully as is possible. I am attempting to get this old truck as close to bullet-proof as is reasonable. In my mind this sort of set up is cheap insurance as long as it is done correctly.

 

Have a great holiday, Jeff

Be aware if you suffer the pin falling out senario that you probably don't want to keep driving and allow the pump arm to fall into the oil pan and possibly try to circulate through the system.

[Jeff Balazs]

That's a good point Ed. I will have to think about this a bit more.

Jeff,

 

Heres something to note... a fellow that i work with is into early 1900's Buicks and Oldsmobiles and hes installed electric fuel pumps on them as they are gravity fed systems. He told me that the electric fuel pumps he put on his cars supposedly do not cause a pressure drop in the system when they are off, essentially its like they are not there. This is what the manufacturer claims which if its true is a pretty cool asset to have. Less restrictions for the mechanical fuel pump the better, just some food for thought. Good luck with this and i agree that this is some pretty cheap insurance thats worth having.

Hi Chris;

Yes that is how I feel about this. As long as it doesn't restrict the flow ...... it sure would be nice to have a back up ready to take over.

Another thought I have had is to just eliminate the mechanical pump altogether and go with electric. By doing this you could do a bit of a reroute on the line to the carb .....and wind up with a considerably cooler fuel supply and less mechanical clutter in a sort of hard to reach spot ?

Hmmmm thats a very interesting thought about eliminating the mechanical pump. I wonder if it woukd be as simple as removing the pump and covering the hole in the side of the block with a gasketed cover plate. I dont see why the motor would care if the fuel pump is there or not, you have the electric one to bring fuel to the carb. Someone please correct me if i am wrong in saying this but it seems like a doable change. Cool idea Jeff.

Chris: I've been mulling this one over also. Why not just remove the inner parts of the pump, cap the holes and install. Be kinda cool. Jeff, if you do this, let us know what pump you selected.

I dont know what brand it is but I have one that was on the truck that was new when I bought the truck and I didnt use any of the drivetrain parts but if you want it let me know. It is a 6 volt and will sell cheap

[rt338b12]

Same pump as I have http://www.ebay.com/itm/6-volt-Electric-Fuel-Pump-for-unleaded-gas-in-GM-can-be-primary-or-support-/151053230285?pt=Vintage_Car_Truck_Parts_Accessories&hash=item232b7960cd&vxp=mtr

Thats an idea too. It would look neat to have the pump still there but not actually doing anything.

My thought on this is that if there is something to be gained by going to an electric pump it would certainly include a rerouted fuel supply to the carb. Keeping the fuel line as far away as possible from the exhaust manifold could be the real day to day benefit of a modification like this.

The engine could care less if the mechanical pump is not in place.

For what it's worth:  Grandma's '86 Diplomat had a 318 with mechanical fuel pump that pooped out, the retired Chrysler mechanic who opened his own shop installed an electric fuel pump in its place.  So if ya looked at it, that fuel pump appeared to be a mechanical fuel pump until ya noticed the wires coming out of the horn area
