Greetings gents I just returnd from a trip after being gone for the month of July. My 40 wont start. Put gas in the carb several times and it runs until gas is used up. Pulled fuel line of carb and turned it over, no gas comes out of the line at all . Pulled fuel line off fuel pump, put my finger over the opening in fuel pump and turned it over. Cant feel any pressure at all on my finger. So need advice on what to do next. Maybe it is the fuel pump. Not sure how to check. Should I try to blow air back down the fuel line. I think I should hear some gurgling if I took off the gas cap. The car was running very well when I parked it for 30 plus days, and of course it has Ethenol gas in the tank and I know better Appreciate any suggestions Dale

Are you sure you have enough fuel in the gas tank? If there is no pressure in the pump outlet line when you crank the engine over, the diaphragm in the fuel pump may have failed or one of the one-way check valves in the pump may have fallen out. Please let us know what you find.

Thanks Is there any way to check if the fuel pump is working or is there a block in the fuel line from the tank

To test with the pump on the car: disconnect the flex line and install a nipple fitting in the pump. If you don't have one, go to NAPA. Run a rubber hose from the nipple into a can of fuel near the pump. The pump should pick up the gas promptly if there is a clog in the line from the tank. If it doesn't most likely a defective pump.

Joe's Antique Auto is my go to source for parts for my '39 p/u. https://www.joesantiqueauto.com/fuel-pump-59a-9350 It's listed as out of stock but might be worth a call to see if it might be back in stock or Joe might have a suggestion of who might have one in stock

If you can't find a complete fuel pump for your car, you might want to order a fuel pump rebuild kit and just rebuild your pump. C&G has these kits in stock. https://cgfordparts.com/products/fuel-pump-rebuilding-kit-34-48-pass-39-48-merc-34-47-pu-v8-with-glass-bowl-11a-9349?_pos=13&_sid=40b62d78d&_ss=r&_fid=5cf876a2f

Send your pump to Charlie Schwindler in Orchard Park N.Y. He rebuilds and test for proper flow and pressure.

Many vendors offer fuel lines that you can bend to make into the proper configuration to fit your combination of fuel pump and carburetor. If you have an inexpensive tubing bender (available at your local auto parts or hardware store), you can also bend your old fuel line to fit properly and be leak-free.
