Posted By Discussion Topic: Trying to get gas to the carb of my '41 -- page: 1 2     martin.scheffer@gmail.com 08-23-2022 @ 10:37 AM reply profile send p.m. Member Posts: 27 Joined: Aug 2022 Recent purchase of a '41. Drove it around before purchase then trucked to my house where I drove it into the garage. A week later it would not start. Good spark so likely gas problem. Blew out copper line to tank. Could hear it bubbling in fresh tank of gas. Disassembled full filter bowl which contained no sediment of any consequence, replaced screen and gasket, disconnected fuel line at carb. Still unable to draw gas. Disassembled fuel pump only to find it in excellent appearance, but rebuilt anyway with clear pumping sound during bench check. Withdrew pump rod which looked in good condition and exactly the same length as a new one I had ordered just in case. Checked pump rod operation showing up/down motion. Left fuel line disconnected from carb and tried to pump some gas out of a can into which I had placed the end of the short rubber gas line leading to glass sediment bowl with absolutely no success. Any suggestions?

From your intro, it sounds like you know your way around the old car hobby, so just a refresher might get you on the road again ! I’ll hit the high points and you can check off the items completed. Gas cap vented. Gas tank clean. Pickup tube functional. Air tight fuel line connections. Flex line functional. Gaskets air tight. Diaphragm and check valves functional. All of the above items are suspect until proven good. Your pump will not draw if there is an air leak, a stuck check valve, or a blockage in the line. Narrow it down and prove each item to find the solution, starting at the pump function itself, draw fuel from and to clear bottles, bypassing all possibles down the line, the first of which being gaskets and connections, and the flex line, which may collapse internally, blocking flow. Bob Shewman sells fuel resistant flex lines, his ad to be found in the V8 Times. Get the one without the check valve, you’ll need a spare anyway.

OR maybe you didn't crank it long enough, it takes time to get gas into the carb if the gas has leaked out or evap0rated.. Rather than crank it and crank it I always pour a some in the top. martin.scheffer@gmail.com 08-23-2022 @ 1:25 PM reply profile send p.m. Member Posts: 27 Joined: Aug 2022 Thanks for your quick response Alan. Could not resist the purchase. Bought my first car in 1953. One just like this, even the same color. It also stopped running fairly soon thereafter. Towed to the garage, where the mechanic handed me a distributor condenser similar to the culprit. It had a full charge. WOW a good jolt. Never forget that moment. Some excellent check off points. I think I am down to fuel line connections and gaskets air tight. I tried drawing gas from the end of the flex line connected to the pump filter bowl - with the line from pump to carb disconnected no success at all. I checked the flex line and it is clear and can see light through it. It appears to be rather new and quite stout with shiny metal ends, however it still could collapse. I think it has got to be either in the fuel pump (which seems hard to believe given that the one I took apart was in quite good condition and very clean, AND then I rebuilt it anyway. So two failures in a row seems a low priority. That leaves the push rod, but the rod was in excellent condition and exactly the same length as a new one I had ordered for this year model. I don't think I could have replaced the rod and its housing wrongly (I did not look very closely at it when I pulled the rod and housing up and out, but it seems to go back only one way, and it moved up and down when cranking) ford38v8 08-23-2022 @ 1:42 PM reply profile send p.m. Senior Posts: 2765 Joined: Oct 2009 Martin, crank the rod to the up position, and place the pump onto it. That will ensure correct positioning of the rod into the lever cup. You'll have to compress the assembly to install the mounting bolts, but you'll know you got it placed right. Pump gaskets are notorious for leaking air. Use oil soaked cork rather than neoprene, and ensure edges are well placed before tightening secure, but not overtight. You might need to prime the pump to get the check valves to working for you.

Always been spooked by a possible backfire. You have helped build my confidence - nothing ventured...... martin.scheffer@gmail.com 08-23-2022 @ 3:26 PM reply profile send p.m. Member Posts: 27 Joined: Aug 2022 Thanks for the good info. I placed the pump arm in the housing and then both down over the rod onto the engine. I had to hold the housing down to bolt it down. I was pleased to feel the tension from that little spring. I am going to recheck screw tightness on the fuel pomp cover and take out the cork gasket from the filter bowl and work a bit of oil into it. I read to "prime the pump." I assume that means to get some gas into the pump. This could be hard to do without taking the pump off as the fuel entry is through the attached fuel filter bowl housing. Will further investigate this idea as a last resort should it come to it. ford38v8 08-23-2022 @ 5:11 PM reply profile send p.m. Senior Posts: 2765 Joined: Oct 2009 Martin, By priming, I meant that the check valves may be stuck from being dry. Just wet them with a little gas while you have the pump top off. Take care with that single top hold down screw, as it will strip out with excess pressure. That gasket and the filter bowl gasket are critical for operation, sealing being kind of a Goldilocks Just Right rather than tight as h*ll.
