Flathead ford won't start on an incline

Hey everyone, I've got my first flathead ford and I've got a rather basic question for one of you seasoned Ford guys. I have a mostly stock 39 ford deluxe coupe with a 1951 8ba mostly stock flathead. The car has a 12volt conversion and a strong battery. I found out today that when the car is parked on an incline in a friends driveway nose facing uphill it cranks easily but won't start. I had just put about 7 gallons of gas in the tank right before arriving. We managed to push it into his garage and once it was level it started up on the second try.

Is this typical? Would an inline electric fuel pump resolve this issue? Anything else I should be looking for?

Thanks in advance

Haven't had a flatty in a while but I wouldn't jump on the in-line until I found out the problem and trid to correct it .
It does sound like a fuel problem. Try unhooking the line to the carb to see if it is pumping when on a hill and won't fire.
If the float has fuel in it, it should start and then run of of fuel if the pump is not working when on the hill, so could be another problem. Like maybe a loos ignition wire.
Try a little fuel down the carb to see if it fire when on the hill.
Problem I had with my flatty,(53 Merc 3/4 race with 3/2's was it would flood out easy. Not when cold but when hot and had only been off a few minutes or if it didn't catch right away. A real pain. My dad had flatties he parked in the driveway that was a uphill and never had a problem. Good luck , Bob.

The fuel pump runs off a shaft that runs off a lobe on the cam. With enough wear, the rod can shorten up and lessen the stroke to the pump. We used to cut the tongue out of an old dress shoe, make a round leather washer from it and place it in the pump cup so that the rod was effectively a little longer. At least, that's the way I remember it from the 50's.

I eventually gave up after several failed pumps on my big (usually 3-5/15 x 4 or 4-1/8) flatheads with multiple 94 or 97 carbs and used an electric fuel pump - Carters always worked best. Turn the key, let it tick 2-3 seconds and it always started. I'm not sure you can buy a decent new US made fuel pump for a flattie these days since they have been out of production for 60 years.

Thanks everyone for the suggestions. I am going to start with the float in the carb, since it has the glass bowl type fuel pump I did notice that the bowl was still full even though it wouldn't start. Cape Cod Bob said something that made me think - initially the car did start and sputter out rather quickly, from there it would not start until it was leveled out. Considering the glass bowl was full that makes me think carb.. I will re-post after I dig into it further!
