Default Electric fuel pump?

Thinking about installing an electric fuel pump. Is it necessary to bipass or remove the mechanical one?

Great question. I may need to put one on my 78. Don't want to but I have the usual issue as well.

It's been done many times though I would eliminate the mechanical pump. I would add a quality pressure gauge and the means to adjust the pressure.

Other opinions may vary.
1. REMOVE the mechanical fuel pump and blank off. The ME fuel pump has a push rod/ lever arm drive...so just removing the diapragm won't be much good.
2. Electric fuel pumps are great...I have a number of cars with them....
3. Filter before the pump is SMART.
4. Dead man rollover or other safety device is MANDATORY!
5. Fuel pressure regulator is a good idea as well.

yup Mandatory ... ALL OE EFI vehicles have one if not two.

Sumting wong if bowls emptying ... how's about fix that?
C3 OE Mech fuel pumps Very reliable -robust
Yes, my more modern motors have OE Electric pump which are reliable as well ... but have R&R several OE in tank pumps ...
... what a pain in *** and when I did pay that labor it's pricey$

-add- so much a pain in *** -wallet$, I cut-in a trap door in bed of my GMC pickup for direct access.

Great point, wouldn't have thought of that. Reason enough to stay with mechanical.

what about a pump by the tank with check valve/s that turns on for about 5sec to prime the system when ignition 1st turned on?

here is a [heated] write up on the C2 Forum about the same thing.

Default cheap rollover inertia switch

As in the other FI thread ... DO also retrofit a rollover inertia pump cut-off switch ... you might use one from an escort
I KNOW they work as I used to slap driver side quarter of my pal's escort wagon ... immediately shuts off ... what fun!

with a a few pumps on the gas pedal to set the choke and a few cranks it should fire off. if not there are other problems you need to fix first. seems to many people are spoiled by new cars and forget what a driving a old car is all about.

It's used on many Ford through the 90's-F150- Taurus- Mustang- T-Bird

Here's a diagram-

Wire the relay in the storage compartment- along with an inertial fuel shut-off- then right from the battery (via the relay) to the fuel pump in the back.. Then just run a wire from the fusebox connected to the ignition terminal. You do not want to wire it to accessory-ignition source (radio/wipers) as the the pump could run when the car is not running in accessory position. Some will recommend an oil pressure shut -off as well. When the engine isn't running (no oil pressure) the pump will be off.
