Fuel Puh puh pump
Thanks guys for your help on previous posts.
Got the rebuilt carb on the 66 f250.
Was running great. but only took it on a few short zips in the neighborhood.
A few days after, the engine just stopped. puuuuuuuuuuuuhhhhhh.
(on the 5 freeway in LA...the worst!)
At first I thought the coil went out. then maybe the fuel line clogged, Then maybe the rebuild carb was faulty. I towed it over to the carb shop. Of course it started, and the guys were saying it seemed to be running fine, but maybe when the motor got warm the fuel pump heated up and lost the ability to pump. Does this sound like a fuel pump issue? This is a 390 (most likely).
It seems to be related to heat, since it restarted after it cooled down a bit. I sort of got it to fire once (when waiting for the tow truck) with starter spry, but it didn't stay lit.
I have a fuel pump around here from an 87 302 mustang engine. I wonder if it is the same as what they run on a 352, 390?

The worst is the 405 aka the world longest parking lot.

If the engine has been swapped, maybe. 1965/67 F100/350's: The only V8 available was the 352 2V / 360/390's were not offered for F100/350's until 1968.

No, absolutely not!

As original, the corrogated paper cartridge fuel filter fits inside a cannister that threads onto the fuel pump. Since most peeps are unaware, they install an inline fuel filter.
And, since they are unaware, the fuel pump filter rarely...if ever...gets changed. Some autoparts store replacement fuel pumps do not have this fuel filter arrangement.
But if your truck still has it, when was the last time it was changed? 5, 10, 15 or lawd only knows how many years ago.
C4AZ-9365-B .. Cartridge Fuel Filter (Motorcraft FG-1A) / Available from Ford and autoparts stores.
Applications: Myriad 1963/77 I-6 & V8 FoMoCo Passenger Cars/Trucks/Bronco's and Econolines.

I just got this truck so you can bet the fuel pump canister has never been opened. I will inspect that. Also just a thought, perhaps the thermostat didn't open up and the engine got hot and vapor locked.
Thanks for the advice AND part numbers. Awesome.

BTW I think this is a 67 352 block with a 390 crank. I need to measure the piston depth. I found a receipt in the truck (1991 or so) for a 390 crank. One of my earlier posts talks about this.

hmmm. That has merit too. Seems like the battery has been draining. I should check the alternator output. Getting this on a 1 wire alt setup may help. Is that a good idea with these f250s? i did that with my ranchero. I'm in new territory here. The temp sender is intermittent btw. I'm going to peck away at these details...

I'd bet the coil is getting hot and shutting down. Works again once it has cooled. Quite common on these older oil-filled coils.

I'm going to apply these simple fix ideas you all have mentioned. Thank you very much for chiming in. They ALL make sense. I'll take her on a "friendlier" path to check her out, and get it up to speed. (5 fwy, bad idea). BTW I was on the way to the recycling center at the time to dispose the bad gas from the in cab tank. They were closed! ooooof. Double idiot feeling.
I'll keep you posted!

The saga continues. Put in a new thermostat to make sure it was opening up in time. Also changed the canister fuel filter in the fuel pump. On the way to get a new coil, it died. Limped to my friends autoparts store. Got a new coil and installed it. On the way home it died. Seems to die after driving a few blocks. I think this is a fuel starving issue. Either the Fuel pump is just petering out or maybe the 2 barrel carb is just not a good match. It "is" a 1.08 venturi. maybe the engine is sucking the little devil dry. After is dies, I have to sit for a while. If i have starter spray this helps (sit for a while, then use the spray) The fuel filter (that was put in line near the fuel pump by the carb shop) is showing about 1/2 to 3/4 fuel level when id cuts out. Might this indicate some sort of constriction somewhere? very puzzled. Maybe there are too many darn fuel filters in line. Maybe the fuel pump should get replaced next. Thanks for any comments.

Before replacing anything else, trouble shoot, unless you just have money to blow.
An easy way to start to narrow down the fuel system is to improvise some container you can use as a remote fuel supply. Connect this containter via a length of hose directly to the carb and keep it higher than the carburetor. Run the engine. If it dies, you know it's nothing in the fuel system before the carburetor. If it continues to run, it probably is something in the fuel system before the carburetor.

Thanks for those suggestions. The engine idles. It will idle all day which is why the carb shop didn't catch it last time because when I towed it to the shop, it later started, they pulled it into a bay, and there it idled for their inspection procedure. In hindsight they should have driven it. It would have stalled. So I need to test this under load.
