Well…they say things happen in 3’s and I present #3. With the new carb everything has been functioning very well. I had to run an errand about an hour away and decided to take the big orange truck. Made it to my appointment smooth as glass. Made it back to Cody which is about half way home. I stopped at Ace Hardware to do a neighbor a favor, that’ll teach me. When I went back out to the truck it took a bit of cranking to get it started and had to feather the gas to keep it running at first. Made it all the way home and the engine stopped right in front of my house. Opened the hood and the carb looked great, but the clear gas filter barely had any gas in it. I turned the key on and the Edelbrock electric fuel pump started running but no gas into the filter. I even tried cranking the engine …nada. Sherry got in the truck and I pushed it into our driveway and left it alone.
About 1.5 hours later I went outside turned the key on and heard the fuel pump started running. I opened the hood and the clear fuel filter was filled like normal and I started the truck right up and it purred like a kitten. The one thing I wish I has done was look at the fuel filter before I turned the key on. Thank you in advance…what do you guys think? (sorry I didn’t take an initial picture of the fuel filter when it was basically empty, but attached is one from my last post ref the carb)
These electric pumps having intermittent issues is probably electrical in nature. Check your wiring, grounds and be listening for your pump operating. If the pump is humming and you don't get fuel then you know it's the pump. Perhaps the impeller is slipping some times? I'm doubting that. My first impression is an electrical issue.

That filter there looks basically empty too. It should be chock full. You have a lot of hose there, is It it possible you have some bends or pinch points in it, maybe another filter before that one that is obstructed? What was your fuel level when you got home. Old tanks can have a lot of sediment floating on top of the fuel that gets sucked into the line when the levels drop?

Definitely check your fuel supply. Are you nearing empty? IIRC Larry just changed out his rear tank for a 38 gallon recently?
Where is the electric fuel pump located? Having a bubble in the top of the fuel filter is normal. So long as it's at least half full you should be ok on that.
Do you still have a return system like the factory had or did you get rid of that?

I am with Dave and was going to ask the same questions.
Where it the pump and the filter half full is fine as mine is the same and I use the factory pump on the motor, 300 six, and filter after the pump.
Oh the restart at the hardware store is also somewhat normal known as "hot restart" and happens just like you posted.
Stop for gas or store run and come back and have to crank the motor for a long time before it will start.
It also runs ruff for a little bit, like it is rich / loaded up, and then ok. My truck dose the same thing and I had a 300 six.
It all has to do with todays fuel blend made for EFI motors and low boiling point.
Fuel sitting in the carb in the center of a v8 heats the fuel and it starts to boil.
When it boils the fuel turns to vapor and is pushed out the bowl vent and vapor being heavier than air goes done the carb into the intake manifold.
Now you want to leave and the intake is full of fuel vapor, read flooded, it will now crank a long time to "clear" the vapor out before it will start.
If you hold the throttle wide open it starts faster as you are letting in more air to dilute the vapor.
Someone posted about adding diesel to the gas at fill up to help fight this well we dont think it works as someone tested how fast the gas evaporates with diesel mixed in and it was just as fast so that is not a fix.
Maybe a different brand of fuel will work better as it may have a different blend? I am going to try this as I have always gotten my fuel at the same station as it is a 1/4 mile from my house.

I’ve got a granddaughter arriving on Thursday so I’m strapped for time. I’ll trace everything down as I find the time. I appreciate the idea and it shouldn’t take long. Even if I replace the pump that should be easy. Thank u
My tank is a new aftermarket 36 gallon tank so it’s clean as far as I know. When I replaced the tank I traced the the fuel line and there is not another filter, but I’ll double check that as I check into the wiring. Thank u
Hey Franklin…right now the fuel filter is almost completely full as it was before this problem started. I do not have a return system. The electric fuel pump is secured to the frame on the drivers side. I’ll try to get under there today and check wiring. The pump does sound a little louder than normal and it never kicks off…I’m not sure that’s normal?
Larry
FF…Thank you for the write up as it answered a lot of questions. There’s still something not quite right here. I’ll get under the truck and trace down all the wires and listen to the pump and report back to you guys. I know all of you have told me if it ain’t broke leave it alone. Because an Edelbrock fuel pump is cheap and I don’t know how old it is I may just replace it…what’s your opinion? 😬

louder indicates the fuel is not getting to the pump itself. Its loosing prime. Try to make sure the hose is smooth and clean and short as you can get away with.
I agree, that clear filter does not need to be full. The air space is normal.
Yes how many pumps and if just the one on the left frame rail where is it to the tank and where is the tank(s) front or rear?
FYI electric pumps should be as close to the tank and below the fuel level, wet inlet, for them to work the best.

Do you have remnants of the return line being there? Most 460 trucks had them. There is a possibility you could utilize that and go back to the system Ford used on the 460 trucks. I guess there was a reason they used the return system on those trucks.
