Jeff I indu Posted November 4, 2023 Report Posted November 4, 2023 A few days ago took my 49 chrysler royal out for a spin. After a few miles it sputtered and died like either out of gas or bad gas. Haven't driven it much lately so i suspected bad gas. Pulled the gas guage and siphoned the old gas out. The inside of the tank looked good but still won't start. Added fresh gas but can't get it to pull to the carburator. Starts easily with starter fluid. Pulled the supply line off the fuel pump and had my wife crank it over while feeling for vacuum from the fuel pump. I didn't feel any pull. Before I order a fuel pump rebuilt kit I was wondering if maybe the pump needed to be primed to pull gas from the tank. I did pull the bowl and cleaned it so it was empty while I checked for vacuum. Just not sure so thought I would ask Jeff Quote
Solution Doug&Deb Posted November 4, 2023 Solution Report Posted November 4, 2023 The pump should pull without priming. If you can rebuild the pump I recommend that over replacing it. The new ones are not well made. It’s possible that the ethanol ruined the diaphragm. A good rebuild kit should have ethanol resistant parts and should last for a long time. 1 Quote

I believe that this is usually done by removing the supply line off the carburetor (or taking the top off) and seeing if you get any fuel, while cranking ? Quote
Jeff I indu Posted November 5, 2023 Author Report Posted November 5, 2023 Thanks for the responses. A fuel pump rebuild kit is ordered. I pulled the supply line off the fuel pump to blow air back into the gas tank. There is no inline fuel filter that I could find. I don't know if the gas tank had a internal screen or not. I wanted to eliminate that possibility. The sediment bowl is the only form of filtration that I can find on my car. At this point I am sure my issue is the fuel pump Jeff Quote
