This post is for those who don't know that running an electric fuel pump as an only fuel pump can KILL you !!! Be sure and use an inertia switch in the electric system going to the pump. I use the ones made by Ford for Mustangs, Fords, Lincolns, etc.; they are on eBay. Cost should be below $20. total.
If you have an accident where the fuel lines are severed or car is upside down and you don't reach out to turn the ignition switch off, you just might BURN to a crisp.
The fuel pump keeps pumping gasoline if the power is not turned off. the inertia switch is suppose to pop out on an impact, etc. and disconnect the power. I haven't tested them that way even tho I have them on several cars; even on the Hudson that I only use the elec. pump for priming and vapor-lock backup. Might forget to turn it off !!
Anyway, you should now get the point: don't be burned alive.
Photo shows the Ford item. Check on eBay. Best to get the wiring connector WITH the switch.
In 1992, I was riding in a Ford Taurus that got tapped in the backend in heavy traffic. No damage, no paint scratches, no stiff necks, etc....
HOWEVER, the fuel pump shut off because of the hit. Luckily the reset was in the trunk in the spare tire well.
Believe all the Ford ones are in the trunk; I have one mounted on the steering col/dash support in my Austin Healey {All have elec. pumps w/o safety}. I can reset from drivers seat-never had it go off. Also have 2 fuel pumps on car.
Every time I hear an electric fuel pump running on an old car I wonder if the owner/driver has installed it correctly. People sure didn't back when I was a kid.
Thanks for the tip Richard. I have tried to send that message to folks for years in different clubs. As a retired police officer I sadly have had to make notifications to families twice of just that horrific incident. Once to a coworker on the loss of his son. There are also oil pressure kill switches that can be installed in line with the oil pressure sender. When the engine oil pressure drops to only a couple of pounds the battery cuts out. However, it is necessary to use a momentary " bypass button" to start the engine since at start up there is no oil pressure. I went back to using a original AC mechanical pump, and use the electric as a primer only. CAN the inertia switch work in a 6 Volts system? Anyone?
I just installed a Carter electric pump on my Studebaker, and I also am using an oil pressure cut off switch. So far I like it! If I ever switch out the Wasp to 12v I will go electric too.
Thanks Ron {enjoyed reading about your Hollywood in the 'book'). Here is where my FORD fuel pump safety inertia switch for the fuel pump is mounted in the trunk on the left side. But of course it depends where you can intercept the wire and mount on a steel structure.
Edit; Don't ask why the wire is visible,; I didn't do it. Trunk is totally carpeted !! Someday I will put wire under the carpet !!!!
The HOLLEY elec. fuel pump(for back-up & prime). Note exhaust insulation next to gas line and Thermo-Tex 1/2" sleeve around the gas line at exhaust pipes.
I have an electric fuel pump in series with the mechanical pump on my old jeep wagoneer. I use it only to fill the carburetor when the car has been standing awhile. It is turned on by a pushbutton switch on the dashboard. I have to keep holding the push button as long as I want the pump to work. This is a simple solution if one only wants to use the pump for filling the carburetor.
Use also for that Mr Hudson Whisperer !!
And for those who may be considering running an original pump and a full time electric, that's not a good idea either. Should the mechanical pump's diaphragm fail, you'd be pumping fuel into the oil pan. Not good!
Sure can!!! It will handle it just fine. I have used 5 or 6 inertia switches on conversions in the last few years. I get them from a salvage yard with the pigtail or connector to wire them in. Most used ones have never even been triggered once. I mounted the last one near the column on the firewall. I told the owner that if he is ever carjacked, to just slip his foot off the clutch, and the car will stall within a block or two.......
