Hecho en CHINA - but it looks the right shape. I'm sure there are still a few thousand NOS original Ford out there, too. The better one from Napa did look pretty good and for $6 it didn't seem a bad price.

I was impatient but it’s so freaking cold out the shifter was real hard to put into neutral to get it off the trailer. So I’m going to wait until tomorrow and use the NAPA one.

Well I didn’t have time to get the NAPA fuel filter so I just installed the one I had. When I pulled the container off I was very surprised to see very little dirt. I saw about a 4” rubber gas hose connecting the gas line to the fuel pump. It looked old and was hard and bridle . So I checked the rest of the line and found the line from the tank was very soft and had chew marks on them. I replaced all the the rubber lines that I could find. I filled up he canister half with fuel before reinstalling. The truck seemed to run great until it stalled again. I cranked it over off and on until the battery died. I had the wife bring me my work truck. It took about a half hour and starting fluid to get the truck running. I’m guessing it could possibly be the fuel in the bowl ran out and it took a while to fill the system and bleed the air out? Or do you guys think I still have an issue. Truck would fire with starting fluid so it was definitely a fuel issue.

I also noticed the truck was running extremely rich. So I’ll check the forum for carb adjustment procedures and if not I will start a post on it.

Last summer my pump started leaking. Bought a new pump from Napa and put it in. The problem was pressure was 8-9psi and blowing by the seats causing high idle. My original pump was a steady 4.5psi and worked like a champ. According to Napa the one he sold me is the only part number they have. My fix was to install a pressure regulator and dial it down. Been 9 months without a hitch. Check the fuel pressure.

From what I can see you have a solid steel line. I would just pull the line from the carb ( should be 3/8 or 1/2 NPT with 5/16 fuel line ) and hook up a 0-10psi gauge with hose or fittings so they wont blow off and crank the engine and read the gauge.

OK, we don't ALL do stupid things...but it is an interesting experiment.

You seem to be missing something from that lever and hole in the carb. Could be a problem.

That is a vent valve and there is a part missing. Also I don't see how that choke could possibly work the way that cable is connected but it could just be the angle that the picture was taken.
Poppatello, Time to hit E-Bay and get a shop manual and make it your bedside reader for awhile. I think you're going to need it!

That is why I took the pictures of the carb. It didn’t look right. While it’s running I get smoke coming out of that hole. And when I move the butterfly by hand it doesn’t move the manual choke lever in the cab. I was wondering if it is hooked up correctly.

If you have or had rubber line on the system and burned regular grade fuel then the ethanol in that will chew the crap out of that stuff and create deposits of small bits of rubber that can play havoc including in your carb.

I've got a couple dozen of those filters. Bought out a small shop some years ago.

PT CG-20
AC GF-157
Hast GF-6A
Puro F21115
Wix 33271

You may still have a line plugged up.

Remove the fuel line to the pump and take an air nozzle and blow back into the tank (gently). Be sure and remove fuel cap.

I had a similar problem turned out to be a clogged filter in the carburetor where the fuel line attaches
