Electric fuel pump

I recently installed a Air tex electric pump on my 51 works great when it sits a
week or two I just use it for priming then turn it off

I use the Airtex electric fuel pumps. Have em in both 6 and 12 volt vehicles. I convert the OEM fuel pumps to 'pass through', and use the electric pump as the only pump. I run a fuel pressure regulator set at 2.5 psi, as well as a 'kill switch' under the dash. that way everything looks stock under the hood and you don't have to worry about the OEM diaphragm failing.

fascinating! how do you set the oem fuel pump to "pass thru"?
and where can one find the regulator?
thnx

I mounted mine on the cross member of my 40 and it feeds back into the uncut original fuel line so I can remove it at any time.

I have posted detailed instructions along with photos of how to convert an OEM fuel pump to a pass through, on my thread "What I did on my lunch hour". You'll have to search the thread as I don't remember what page(s) the information is on.
 
Is a electric fuel pump better pushing fuel vs pulling fuel up to the mech pump. I am putting one on my 35 F cpe. thanks Tom
 
No matter who’s pump you buy here is the fact
Electric pumps push better than they suck so you always want to mount it as close to the tank as possible .

Don’t mean to hijack but electric fuel pump running after a crash has always been a concern of mine.
When I rewired the 49 I repurposed a Fuel Pump Inertia Safety Cutoff Switch. FOMOCO has used them for years and put them about anywhere imaginable (under the dash and in the trunk mostly).
In the old days I used the run side of the ign switch for pilot duty to a relay feeding a 70s brand X oil pressure switch for run and the Ford starter solenoid ign terminal for startup.
 
I use an Aixtex 12 volt and don't need a regulator. It puts out 3 psi, same as my OE mechanical pump. I use it for pre-start and used it once for driving when I got a vapor lock situation.
