No gas

Hey Woodie & Ford38. I thought that pressuring the and pushing the gas to the carburetors worked on the same principal as an electric pump. Anyhow no gas got through to the carburetor supply line. This engine doesn’t appear to have a flex line in the engine compartment. All are metal lines in the engine bay.
I took the diaphragm apart and I can’t see any defects. What do you think?

Ricosan,


You got the car delivered to you, right? I am so curious if the delivery guy able to drive the car into the transport? Is this the same car with the trans issue or a different one?

Good luck.

Richard, this has nothing to do with your current fuel problem, but I thought I should mention this; there should be a flexible line, p/n 18-9288-A, between the fuel supply line from the tank and the inlet of the fuel pump. Otherwise, all the engine vibration will be going into the solid line and something is going to fail.

Good luck with locating the blockage in the fuel supply circuit.
 
Good morning Tim, The car started when it was delivered and I drove it 4 miles before it quit leaving my wife and I stranded on the side of the road. Tow truck home.

Zeke, there doesn’t appear to be a flex line. My plan this weekend is to install a piece of rubber line where the flex line is generally located and check the attachment to at the tank to make sure we are not sucking air there.

You have nothing to lose at this point. Drain the tank into a 5 gallon can with a funnel covered with cheese cloth. Then you will know what the starting point is like. Floaters in the tank are unpredictable. Had this problem with a restored 33 truck with 10 miles. Sometimes they put gas in from a can because its easier than getting it to to the station and this contaminates the fuel.
 
This afternoon I added a flex line to the gas supply. Right now it’s only temporary, just a short section of 1/4” rubber fuel line.

CSCOV I’ve run gas through the line on several occasions and never saw any signs of trash. Even with the sediment bowl full, it still won’t pull gas through to the carburetors. I haven’t been able to get to the attachment at the rear tank.

I’m to the point now I think I’ll just order another fuel pump.
 
Can't you check the pump on the bench?
You should be able to blow through the inlet, but not through the carb side.
Manually operating the diaphragm with your finger over the the ports should give you vacuum and pressure respectively.

One thing you need to get rid of is the “just order a new one” mentality. You have a vintage machine in a modern throw away world. Nothing is made today to the quality standards of yesteryear. The most rewarding aspect of this hobby is the mastery of the machine and all it’s systems. Learn what makes your Ford tick and you’ll never be stranded again. You’ll beam with the pride of ownership you have not experienced before.
Start with this fuel pump you have now. It’s the simplest of all the systems in your Ford, take it apart, explore the function of the check valves, discover what it needs to make it work. Do it yourself and you’ll never again “just order a new one.”

Love this advice. Great post. Not easy sometimes, but the right way to go about it.

hear hear. Back in the day, there was a reason for a service station on every street corner.
 
UPS delivered my electric fuel pump yesterday. I’m going to try to rig it up temporarily and see if if I can get gas flow to the carburetors.
 
I think I read all, I didn’t see this as an easy check on your pump. Disconnect gas tank feed line into the pump. Put a fresh piece of flexible fuel line long enough to go into a gallon container of fresh gas. Disconnect feed side of pump line at carb, crank engine to see if pumping gas from gallon container. I’d bet you will. At least that’ll tell you if your prob is @ fuel pump or the gas tank feed line & or in the gas tank.
 
sometimes a leather shim can be placed on top of push rod, giving a longer stroke; and it will pump, if rod is worn
 
what pressure is the electric pump? you will need a pressure regulator if it is more than about 2.5 psi.
why haven't you diagnosed the problem with your original setup? i suspect the check valves as it has been running.
you have a rubber hose at the firewall. disconnect it and put a long hose on the pipe feeding your pump. you should be able to blow through it and not suck.
if it passes that test empty the sediment bowl and connect your electric pump up to that hose and a small container of gas. it should fill the sediment bowl and carbs and should start and run!
if every thing goes well the problem is between the firewall and the tank.
 
Hey Guys,
I am convinced that the problem is inside the fuel pump as I have tested every possible way to get gas to the carburetor side of the pump. From both sides. The rod looked perfect, it moved up and down when the engine was rotating, the cup on the on the fuel pump is in perfect shape.
When I put pressure at the tank, the sediment bowl will quickly fill.
Pressuring the tank pushes the gas to the sediment bowl The gas is at the pump door and eager to enter the fuel pump and do its job. I pour gas in the carbs and crank the engine it fires up and abruptly shuts down.
I also screwed in a male hose adapter at the supply side of the fuel pump (the one going to the carburetors)and attached a short section of hose. With gas in the sediment, I turned the engine over. No gas.
I really think, with the help from everyone here, I’ve narrowed it down to a blockage in the fuel pump (gas just won’t pass through). So I plan on taking it apart today at least to the point I can find the blockage.
 
If your gas tank has been cleaned and sealed with any of the various products it could be that the inlet pipe that is part of the gas tank is plugged up. I had a similar problem with my 36 so I installed a new Drake tank. Later on I ran a long 1/8 drill bit into the pickup tube in the old tank and pulled out a lot of debris, etc. I could have saved quite a lot of $$$ if I had pulled the original tank first.
