Electric Fuel Pump Install

Long story short, I need to replace the mechanical FP on my f134 with an electric. Picked up the Mr. Gasket 42s that I read about here. Just wondering if I need a regulator on it.. its output is 2-3.5. I am using a carter 1bbl yf.

Any other tips for using this style pump?

I am using an under seat m38a1 tank, where is a good place to mount this pump?
No need for any roll over protection..

thanks

 

In the frame channel below and close to the TK. I put a 1/4 turn valve between the TK and the elect. pump to shut off the gas if I had to work on the pump or filter. My set up from the TK is block valve, filter, elect. pump and the line to the YF carb..

 

Did you install the electric pump? I am thinking of installing one on my 1970 CJ5. Did you use a regulator?

 

yeah it was super simple. works good. I did not install a regulator, but I will be soon. Not sure which to get though..

 

I am tired of swapping out mech. pumps. On my third one and it only lasted a year. Considering a HOLLEY 12-427. I think it is 4-7 psi. I will likely go with a regulator. Saw one on a jeep in a photograph and I am trying to find the photo now. Are you concerned you are over feeding the carb?

 

The holley needs a regulator. The Mr. Gasket should be alright without. I don't have a regulator on my Mr. Gasket system. Mounted inside the frame rail for protection would get it lower than most of the tank, which you want/need to keep from running the pump in a dry condition. I have mine mounted on the inside of the drivers side fender because I didn't want to cut the steel fuel line that was there for the mechanical pump. See through fuel filter, the pump, another filter and then into the original line to the carb. I used heavy duty fuel line to go to all the connections..

 

Ok, any last tips or advice? 1970 CJ5 Under seat tank. 134F. I have a HOLLEY 12-427 pump. ( I am using this because it is approved to use with ethanol blended fuel.) I may not always be able to find non-ethanol in my area. 4-7 psi. With a HOLLEY 12-804 regulator 1-4 psi. I plan to put the pump inside the frame rail below the tank, brake lines permitting. Likely going to put the regulator on the fire wall under the hood in front of the driver. I plan on using rubber fuel lines with a filter before the pump and one before the new solex carb. I feel I will be more successful in routing the flexible lines away from the exhaust. Painless electric fuel pump wiring kit. Going to put a lighted on off switch in front of the driver however, the pump will be connected to the ignition switch. Fire extinguisher mounted to the roll bar behind the driver seat. Any better ideas????

 

when you first turn on the ignition, give it a 5 count or so for the pump to pressurize the system. Only needs it on the first start of the day. Then engage the starter.

 

Exactly what I do I fires up right away too.

 

Really there's no advantage to a regulator on a low pressure pump like that, some will actually create MORE short-acting surge than the steady thump of a fuel pump.

Does anybody still sell a bellows-type fuel pump for reasonable money (like the old Lucas pumps)?
I like the idea of an electric pump but not interested in the high speed dup-dup-dup of the solenoid pumps whenever the vehicle is on.

 

There is if your carb won't handle a psi higher than 2. Like the Solex.
The Carter will likely handle it all right. But not all Mr. Gasket electrics are that low pressure. They also make a model that looks the same and even comes in the same packaging. You have to read real close to make sure you don't have the high pressure model.

 

Also, I can not hear the pump once the engine is running.
