Re: 1936 Packard 320 ci fuel issue

Thanks for the ideas, I checked my fuel pump fuel pump bowel and screen which look clean as new ones. On the needle and seat, I see no dirt in the carb, and when I first start it, you can watch the pressure change cold from about 4.5 psi to about 4 and back to 4.6 again as the needle opens and closes. It then slowly goes to 0 as it warms up.

I get 3/8 inch. I left it in place. With the gaskets is slightly more than .4 inch. Thanks for checking.

The block looks original, but you never know what has happened in the last 90 years. I could use the measurement. It would be one more potential problem I could eliminate. Thanks

It was rebuilt this year. I sent it back. The rebuilder is going to look at it again. I am going to crank the engine to check cam stroke.

Fuel flow goes to a drip if I disconnect the line at the carb. I checked the hardline to the carb. it is clean and flows freely. Since the tank is normally lower than the fuel pump, I thought it would be best to put the test gas can at the same level as the tank to mimic the tank.

It can't be the gas cap since I am running for the test, on a 5-gal fuel can with the cap off. The pressure drops incrementally in 10 minutes. It will restart in about 20 minutes with 2.5 psi. completely cold engine then goes back to 4.5 psi, but repeats to 0 psi in about 10 minutes. I don't think I can isolate it any more without making a rig with a cam to operate the pump lever. Any another idea are appreciated! Thanks

I have 1936 Packard 320 ci that goes from 4.5 Psi to 0 fuel pressure at the carburetor after the engine runs for 10 minutes (engine dies at 0). I have had the pump professionally rebuilt. I used an auxiliary tank at the inlet to the fuel pump to eliminate any tank/line problem. I also run ethenyl free gas.
Has anyone had a problem with the pump push rod?
Any other ideas? Thanks

If you can find a part number, Bruce Blevins at the Packard proving grounds has blueprints.

My 32 deluxe 8 had a hole in the front of the cam shaft plug, but it was smaller than 3/8. I think it was to get oil to the timing chain. I saw a couple of disassembled engines in the parts section of Packardinfo . Maybe he could measure the hole size.

Thanks, I've seen some red oxide, and some body color, but not very thick body color paint. I haven't seen any that look like they were totally original factory paint. Thanks again.
