Re: {Chrysler 300} Electrical fuel pump

Dyke, 1.5 psi will put gas in the carb bowl. Even if it couldn't overcome the needle fuel would still be at the mechanical pump and close enough. I am not advising using an electric pump in place of a mechanical pump. I am saying a 1.5 psi pump is all that is needed to prime our cars for an expedient start.

It is safer to stay with a low pressure pump for this application.

Just to be clear and cover all the "Letter" cars, the fuel pressure specification for the Carter WCFB is 6-7 psi.

Carter AFB carburetors are designed to require 5-8 psi fuel pressure. A electric pump putting out 4-6 psi is correct for the AFB carburetors.

Just in front of the tank. I would ignore advice to use a 4-6 psi pump. That could overcome a needle and seat. Fact is 1.5 psi has been working flawlessly for many years for many in the hobby.

What is the ideal location for the facet pump?

Just wanted to add, The existing mechanical pump stays in place and pulls through the priming pump once started.

Agree with Danny, I’ve had one on my G for at least 15 years that I got from John Lazenby, and a different style before it. They really are necessary if the car sits for more than a week due to gas evaporation. Install with a push button switch. Turn the key on, push button until pulsations slow, then crank over. Simple, effective, no cranking, cranking, cranking. As John G mentioned, some folks think the cranking helps pump oil before firing and beneficial. Personally, I don’t agree, unnecessary wear on the battery and starter. Besides, if you did want to crank it without priming, you’d still have that option, just don’t push the button. As far as opening the hood, unscrewing the air cleaner, pouring gas in the carb…what a pain, and a bit dangerous.

You want a Facet cube pump. Its a little cube, pumps 1.5 psi and perfect for priming. John Lazenby installed one on my F when he owned it.

The Facet will pump through the mechanical pump. I run it until she starts and then turn it off. Google a Facet 1.5 psi and it will pop right up.

The electrical fuel pump on my 61G gave way and started leaking. This pump was installed prior to my purchasing the car. I only turn it on for about 20 sec. prior to starting the car and then turn it off.

Question.....Is this something really necessary (I did replace the mechanical pump about a year ago)? If so, what would be a good replacement and what would the required GPM and PSI (there is no notation on the pump to go by.)

See attached for what was installed by a previous owner.
