Electric fuel pump 37 Ford

If I install an electric fuel pump near the tank on my 37 Coupe can I still leave the mechanical pump in place or do I have to remove it and install a block off plate? Any other thoughts on an electric fuel pump installation?
Thanks.

I tucked mine up in the frame rail just forward of the rear axle. Put it on a switch under the dash. Used an Airtex E8902 electric fuel pump off Amazon $35.
Still run the stock pump and haven't had any probs. With the exception of no stalling on hot days cause the vapor lock up in the vacuum pump. I dont run it all the time either. Mines 12v but they have a 6v as well



 
Just installed a 6volt on my 35. Overhauled the mechanical pump to prevent leaking and for look. Only use electric on start up after sitting awhile, then turn off. Important to have a good needle and seat in carb.

You will need a pressure regulator set to 2 ~ 3 lbs.
More than that will override your carburetor float valve.
 
To minimize the unpleasant noise from the electric pump, install on frame with some sort of hard rubber insulation between pump mount and frame. Rubber hoses for the fuel line connections at the pump will also help.
 
This is only if your car is not original ........... install the electric pump near the tank. Run a separate line, with an inline filter, and T it in between the mechanical pump and the carb. This set up allows you to pump gas to the carb if the car has been sitting, or anytime you experience vapor lock, or if your mechanical ever fails ..... you have a redundant system .

If you run the fuel from the electric pump thru the factory pump, it will run. But if the diaphram fails in the factory pump the electric pump will be pumping fuel into the crank case and you will ruin a engine. Vic Piano has plans for building your factory pump where it will not operate but you can run the fuel thru it and every thing will look original with out taking a chance on getting fuel in your crank case and ruining your engine.

Although I will look at my fuel pump when I get home this evening, I thought most pumps have a weep hole on the bottom to help prevent leakage into the crankcase. Flathead pumps may be the exception.

So the Airtex pump allows fuel to be pulled through it with mechanical? You don't need the bypass plumbing? Also if just using like you say for infrequent startups and an emergency you may not need the regulator before Stromberg? I bought the Airtex few years ago and I think it is 6 volt never put it on. I had the mechanical one that was just rebuilt and "ethanol proof" fail on a very busy state route and the backup would have in the very least got me off the road. This may be the winter I cut into the fuel line.
