I got a dual action fuel pump from a member in 2022. I just went to start my rebuilt engine for the first time and the fuel pump isn't sucking any gas.The engine is on a stand and the gas is in a container that I have used several times for a fuel source on engines without a gas tank. Right now I just want to purchase a new standard fuel pump and deal with the dual action later. I have check a couple Ford parts supplies and they are out of stock. Anyone know where to get one? Thanks
 
Watch that you don't have an air leak in the fuel line. - the flexible line is the first place to look, rusted steel line also, or the pick up in the tank. Also, there could be an issue with push rod length.
If I knew where you were, I might offer to loan a used one...

i simply googled "1952 8ba fuel pump" and came up with this. https://www.dennis-carpenter.com/trucks/fuel-system/fuel-pump/578-9350-a-fuel-pump-v-8

but if the object is to simply test the engine...

depending on where the pump is and where the gas tank is, it's hypothetically possible to be demanding too much lifting from the pump...any pump. if testing the engine is the goal, it might be better to simply move the tank to a position above the pump.

of course if the object is to test the pump, that's a different story. :)

I did the same on google. Dennis carpenter is out of stock according to his website, Concourse does have the standard pump listed and Speedway is out. The tank is 1 foot higher than the fuel pump with a 1.5 ft tube. I will send a message to Karl as I am only 70 miles away in San Jose.
 
"Scott52", I just heard from Charlie Schwendler in New York who is the recognized expert on all things fuel-related for these cars. If you contact him, he says he can help you. He is one of the very best resources around. Try him.

On your dual action pump, make sure you have a good seal at the glass bowl. Make sure the gasket is a cork gasket as opposed to a neoprene gasket...

In order to start my recently acquired engine I installed a “Model A” fuel tank which worked quite well, lol.

I had a double action(not original) pump on my '50 and when I removed it and felt the effort it took to operate the heavier spring, I decided to switch. I found a NOS in the box AC pump for a very reasonable price on ebay and put in a rebuild kit (the diaphram was toast). It has worked fine for several years. There are some on ebay now, mostly new. Of course, I checked the length of the push rod and the lift, s/b about 1/4".

Ordered the Rock Auto Pump
Thanks for the Contact Info on Charlie, That's who I got it from 4 years ago but never tried it until now.
I actually have a coffee can with a fitting on the bottom that would replicate the "Model A" temp gas can. For the life of me I can't remember what I used it for. The brain is starting to fail.
I have been taking some measurements on the travel and height of the push rod. And the depth of the full pump actuator arm on my rebuilt double action and the original Fuel pump. Due to the brain issues, I want to repeat these. It feels like pushing on the actuator arm doesn't take much resistance. It does return to its static position. I am used to the hard push of a flathead Dodge or SBC fuel pump. You really have to push and you can hear them make a sucking noise.
I have used the gas container in the photo several times in the past 15 years to start SBC and Dodge Flathead engines.

Looks like you have the same Mr. Gasket air cleaner that i have on my '51.the research i had done said was perfect size for the 239. also looks good. Tom.
 
It should require a bit of effort to operate the pump arm by hand. The pump on my 8ba has no problem lifting fuel from a gas can sitting on the ground. The gasket on the fuel bowl and the flexible fuel line are common sources of air leaks.
 
Got the Fuel Pump from Rock Auto, USMW Professional Series # USMP02065 578 Mechanical Fuel Pump. The first thing I noticed, It did not have the same standard pipe or flare fittings I expected and my box of various fittings did not mate with it. I spent some time trying to find a diagram and finally found a call out for either the in or out, I forget which saying 1/2-20 fine thread. I found a bolt and tested in and out and that was correct. Went to the local fitting shop "Royal Brass" and for $30 got what I needed.


Did a bunch of measurements to verify the pump rod
Original 2 barrel Manifold thickness 2.31 Edelbrock 452 Manifold 2.30
Pump Rod 10 1/16 inch Spare 8BA rod 10 1/16 inch
Depth 2 Actuator when pmp mounted on stand Orig pump 1.96 Dual action Pump 1.95 Forgot to measure Rock Auto Pump or Didn't write down
Rod Travel Lowest Above Manifold 2.22 Highest Above Manifold 2.42 Travel .20
Tested Rock Auto pump on Bench pushing on actuator with a dowel in a vice, sucked gas
Installed on Manifold and cranked engine and gas came quickly and filled bowl.


Next I need to try the dual action pump again. I did change to fuel line and filter to my plastic jug. Could have been a vacuum leak but now I know I have a good set up
