Dixie OP top fuel Joined: Jun 2008 Posts: 2,336 Ball Ground, Georgia	Hey Guys, The fuel pump on my car is letting the fuel drain back out of the carb. It doesn't want to start after a couple of days sitting. Any recommendations on who makes a good mechanical pump these days for a stock 440? I believe the one I have on it now is a Carter M4862 and about 12 years old. Really hasn't been used enough to fail. Thanks!

My car sits for months at time now and starts after about 6-10 revolutions and some petal pumping with a ordinarily mechanical fuel pump.

Don't waste your money on a new pump Agree the pump is likely fine... especially if it runs OK after starting. Fuel evaporation is very likely. I have switched my carb vehicles to electric pump for this reason. Key on for a few seconds re-primes the system and starts right up. This also can eliminate vapor lock.

I originally thought that today's cheap gas was just evaporating, but I recently put 110 racing fuel in it and had the same problem. Carb dry after sitting a few days.

Usually takes a week or two of sitting. I fill the bowls using the electric pump on the cars that have them, or fill manually through the vent tubes, or just spin 'em for a bit. They're certainly not like EFI.

And I have a nearly new mechanical Racepump that I'm not using. If interested, let me know.
