Is hard to start. It’s a carbureted 351 W It has to be primed if it sets more than a couple days. Runs good after it’s started. Was the same way when the ole 300 6 was in it. Is there supposed to be a check ball in the tank or something? I’ve replaced all the rubber lines. |

Is having to refill the carb as the gas evaporated away. A distinct problem with the old Aluminum carbs after been ‘tanked’ or Washed in caustic for rebuilds. The Anodizing is as much a sealant as a corrosion protection, aluminum itself is Porous, aged wheels will leak air, carbs fuel evaporates, throttle bodies on EFI will not idle down low enough. All becomes the issues seen. Adding a electric fuel pump on a Oil pressure switch to accident shut off with a Cranking power bypass as GM did on the early TBI units is about the only way to repair but not really fix. |

Brand new Edelbrock carb on it now. Before was an old single barrel on a 6 banger. Can I use an electric pump just to prime? Will the mechanical pump, pump through it? |

I struggled for years with the same problem on my 74 F-350; did everything trying to fix it "right" and finally capitulated by installing an electric fuel pump in line ahead of the mechanical pump. I wired the electric pump so as to run only while the starter is engaged. Edit: I am using the electric fuel pump to pump THROUGH the mechanical pump. My reasoning being that sometimes this truck sits for weeks or even months without being started so if the engine has to crank a few revolutions before getting fuel then it also has opportunity for the oil to get moving before firing up. Maybe that is looney logic but that's what I did. This method also ensures that the electric fuel pump is NOT energized should the engine die for whatever reason. It only requires two or maybe three seconds of cranking before it gets fuel and fires up, after the initial startup it re-starts almost instantly. |

you could just use a toggle switch.. Flip it on for 5 seconds, then crank.. I would use a MOMENTARY switch so you have to have your finger on it to run.. ------------- Like them all, but love the "B"s. |

I contemplated doing it that way but chose the more simple method of connecting to the starter relay because: A) It was cheaper (I really am a tightwad) and easier than mounting another switch. B) This actually happened; I was broke down elsewhere in a different vehicle, called my Wife to bring the truck to rescue me and it wouldn't start. This was the incident that prompted me to install the electric fuel pump. The last thing Mama needs is an extra button or switch to fiddle with in order to start the truck. My method makes it automatic; just turn the key and it fires up pretty quick.
