I'm not sure why I have to pour gas into the carb. It will start if I don't do this and crank for about 60 sec. I assume there is a bad check valve in the fuel pump, or some problem in the carb that makes the gas go away.
Anyway, after suffering for 39 years here is my plan to deal with all this:
I'm going to replace the Rochester carb with a Carter YF 2100s. This weekend if I get 'er rebuilt.
I have bought a double acting fuel pump which I hope will help with starting and the wiper situation.
I have a couple of questions.
What is the best way to run the vacuum lines from the fuel pump? Seems like I saw some drawing where they were run under the front of the engine and then up. (Engine is a 235)
What diameter lines are used for these vacuum lines?
Can I run the pump without connecting the vacuum lines? can I plug the ports on the pump if I do this? I drive the truck most days, and it may be a while before I can install the lines.
The new pump has a glass bowl sediment filter. I already have an aftermarket glass bowl filter at the carb. Any downside to having both? Or it this just redundant?
Thanks for any thoughts.

When I first started on this panel I've got, I had to do the gas dump to get it to start. I had a tiny leak in the fuel line where it connected to the pump. Darn thing had me stumped for a bit!
In my future, is one of those great dual pumps. So far I'm too cheap. | | |
