Mine started with a tow home Friday night. Purposely ran it dry off the main tank and flipped the switch to use the aux tank. I've done it before, but this time it never restarted. No fuel to the carb...nothing at all. My father-in-law has a trick about blowing into the tank while cranking the engine..that got some gas to splash in the clear filter but still no start. Took the line off the carb, no fuel while cranking. Tried blowing through the hose after reconnecting to carb, no air going into carb.

Over the last two days I replaced all the rubber lines between the tanks and carb, and added a filter before the pump, so now I don't have a filter between the pump and carb. I moved the vacuum advance hose back to the side of the carb instead of the front base, a change made by a friend that I was never 100% sure about. The tank selector valve was loose, so I found the bolts under the mat and tightened. After all of that the truck started right up and idled well, and the initial test drive was good, but it started acting up again later. Changed the pump after eliminating most other options, and a 20 minute heavy-footed drive outside of town went well. I'd love to hear any tips on getting both bolts tight on the fuel pump (390, had power steering pump out but oil sending unit would not budge. Back bolt is snug but not tight.) Someone at Ford had a bad engineering day when that bit was designed. The pump itself blocks access to the mounting bolts.

I replaced the power steering pump while I was at it. It has been leaking and is in the way of the fuel pump, so it was a win-win. I hate leaks. So, in the last month I've replaced the plugs and wires, power steering pump, fuel pump/filters/hoses, and valve cover gaskets. I would like to get going on the exhaust system. I hear a slight leak on the passenger side......thinking headers and 3" duals may fix it.

 

Sounds like you had it easier than me. I've been fightin either a case of Salmonella poisoning of stomach flu for the past 4 days.

 

sounds like my weekend
stomach flu Saturday and truck problems Sunday .

Baddad there's a bad stomach flu going around , my neice had it to and went to the urgent care Doc said seeing alot of it right now .

 

Granpa, If you pull the tank side line at the pump gas will run out if it is present. If none flows you might want to blow compressed air into the line with the gas cap off, then see if any flows.

If you have gas on that side you should have gas in the line going to the carb when cranked over if the pump is working.

Things were pretty simple in the 60s, don't know why your FIL is blowing into the tank, sounds like a blockage to me. Maybe pull & clean the tank.

Flow out of the tank was good when I replaced the hoses around the tank selector valve. Blew air backwards into rear tank with cap off, no blockage and I could make it sound like an elk call.

FIL learned that trick working on his riding lawn mower. It won't always start, especially after gassing up, but some air pressure gets it going. I'd love to drop and clean the tanks, and replace all the hoses and lines directly connected to them. Filling the tanks takes time and patience due to backflow, plus they build pressure and push gas out past the caps. Need to check the vent hoses. If I ever get that far into it I will probably just drop in a single 38 gallon tank and eliminate some plumbing.
