Re: 1952 - 250 fuel pump question

I have a '52 250 as well. I run an airtex 6v inline with the mechanical pump. If my car has been sitting for mare than a couple weeks, I will let the pump run for 30 seconds or so to get gas back into the carb before I try to start it up. Otherwise, it is always off. The car starts quite quickly.

If your pump is leaking, you have to fix it. An electric back up is your choice. Make sure your choke is working properly and correctly adjusted and that you have no vacuum leaks. You have a couple vaccuum lines that come off the gas jump, so check those for leaks as well. I think if you get that all sorted out, it should start well with or without the electric pump. Of course, if it has been sitting for months, you either will need to prime it or grind it till fuel is pumped up to the carb.
