EDIT:
I think I’ve found the problem. See the last post. ——— I’m getting my engine broken in with a single carb. The fuel pump is located in the engine compartment. When I hook the carb up to the fuel line in the car, it doesn’t get fuel. The pump never quiets down, and no fuel. When I put a fuel line from the fuel pump directly to a gas can next to the car, it takes fuel and runs fine. The pump quiets down once it gets fuel. Everything works fine. When I blow air back through the fuel line from the engine compartment, with an air hose, you can hear it coming out in the gas tank. So I don’t think the lines are clogged. Any ideas why I’m not getting fuel out of the main line with the pump? The line is a hard line. It looks like someone has replaced the plastic lines. The car had carbs when I bought it a few years ago. |

I think I’ve found the culprit. It looks like the previous owner used a very long fuel line from the tank to the main center console hard line, and it might have gotten kinked when the tank was put down in its spot. They probably used a long line because it’s easier to get it hooked up.
Here is my question - if I use a very short line, can I access it to hook it up, through the round hole beneath the tank (photo below), from beneath the car? Attached thumbnail(s) |

I don't think so, at least not easily. Shorten the current line a bit if needed and lower the tank so it doesn't get kinked. Maybe access the fuel line through the hole to help position it.

There is then less chance of forming a kink that will cut off supply from tank. (IMG:style_emoticons/default/barf.gif) I eliminated the notoriously troublesome sock filter in the tank, and have a filter installed before pump up front and another filter in the engine compartment. |

[/quote] I disagree. All my cars were refitted with Tangerine racing SS fuel lines and new high pressure rubber line. The small length of rubber fuel line has never kinked. A long screwdriver keeps your hand from blocking your view. Just use a small led light to inspect your work and remember the proper type of fuel clamps. I also put a touch of MMO in the line so it slips onto the tank easily. |
