Re: {Chrysler 300} Inline Electric Fuel pump

good point!

I did not say , I should have, and actually very important , the “ sock” in the tank clogs , sometimes intermittently as junk held to it falls off when you stop . That hassle was the reason for external mesh filter

Throw it away , the new SS mesh captures the junk -if any - outside the tank !

10 minutes to get rid of it vs dropping tank , or pulling sender etc etc

Not doing that on a winter day or middle of nowhere is well worth 40$. Car keeps going ..

I’m just curious if the tank has ever been cleaned out. Even if there is some unwanted material floating around in the tank, there should be a nylon filter at the end of the pickup tube to keep unwanted particles from heading up the line. These filters tend to disintegrate after sixty years and should be replaced. I would also get a pump with proven reliability. Maybe the one that Danny mentioned ?

Thanks Danny. I have not taken the pump off the car yet to examine it and check for 12V at the pump. My main question is whether a pump would allow fuel to pass through if it was clogged? Since the engine runs fine, it seems like it can’t be clogged?

The very first pump that I used was purchased from John Lazenby, but that pump failed after several years.

Regards,

Mark

When you remove these pumps from the car, can you make them run with 12 volts on the wires? Pending weigh-in from Don V & John G I would imagine any debris sucked up by the pump would have fouled the carbs.

If you know your source of 12 volts to the pump and the switch are OK, I would ask Auto Zone for a Facet cube pump, many of us use it without a problem.

Another thing...after I watched one of Bob Merritt's videos in which he is seen priming carbs through bowl vents with a squeeze bottle I stopped using the pump. This works much better, car starts instantly. Use 2 cycle fuel from the auto parts store. This way you are under your hood, can check oil and see anything that should be seen.

My F will start on one revolution of the starter as long as it was running within the last 7 days.

Drive your cars!

Fuel Pump is Auto Zone part number is A8016EP “Spectra Premium fuel pump” made by TRUGRADE FUEL SYSTEMS. Just Google A8016EP and a picture appears.

When working, a distinct sound can be heard. Now there is no sound. If the pump will not work (perhaps due to being clogged), it seems like the engine would not start due to lack of gas?

Perhaps the motor is just burned out and it is not clogged? Again, the engine eventually starts (using the engine mechanical pump after some cranking) and the car runs fine.

Mark-

What pump are you using? Facet? What is the failure mode, blowing fuses? Cannot hear it run?, Will not pump?

There is a Facet cube pump on my F mounted ahead of the tank. It needs to run a few minutes to fill the bowls and it is quite audible. There is no filter behind the pump.

Knowing what "failure" means might help us.

Hello All,

I have gone through 2 electric fuel pumps in about 12 years, the last one under life-time warranty at Auto Zone. They replaced it at No-Charge pending return of the old one. A few questions.

A local mechanic gave his opinion that the last pump may have failed because I did not put a fuel filter in between the gas tank and the pump.
The 300 runs strong with the failed primer pump, so my question is, “Could the pump be clogged and not working while the 300 starts up (just using mechanical pump from engine) and runs fine?”
It is mounted above the rear axle, just after the gas tank. It has a separate switch that is for prime only and the pump does not run other than for starting the engine.

I can replace the pump to include an inline filter, but I don’t like to put extra splices in the rubber fuel line (under the car) if the cause for the pump to fail is not due to the lack of a fuel filter.

Thanks in advance for your comments.

Regards,

Mark Lindahl
