220 mechanical fuel pump

Post by TDezso »

Just got this boat on the water and the electric pump took a crap on me 5min on the water. Checked out the factory pump to see if it was usable and it's internals are junk. I did some searching and found the pump from a late 70s dodge works and I picked one up. So I noticed the lever doesn't ride on the shaft like it is supposed to. It has about 1/4" gap. Is there another option for a pump besides factory? Maybe an aftermarket performance pump like Holley or edelbrock?

1984 Plymouth horizon 2.2 fuel pump works. You can also get an overhaul kit for the factory Carter pump and rebuild it.http://www.zip-corvette.com/56l-57-fuel ... oCr9Pw_wcB

Thanks for that link. I think my pump needs the brackets that hold those baskets in. I wonder what the difference is between the horizon pump(#60321) and the valiant pump I got (#60577). I just don't like the way the lever rides on the shaft. I feel like it's going to wear it out betting on it instead of riding on it.

Beating on it vs riding on it, you aren't getting full throw from pump, heat the arm and bend it to where you have zero lash and a slight preload on lever.

It doesn't have much throw in the pump. I think if I bend the lever, it's gonna want to pass the bottom out position. The stock pumps seem to have a lot more throw for the size of the lobe on the shaft. This pump seems to be run on a smaller lobe. Maybe I'm not making sense when I'm typing. Lol

No sir, lycoming is of much different design, these are from 56/7 corvette, Holley sold them as high volume pumps.

Just wondering, have you ever found a rebuild kit for Lycoming?

Just throwing this out there. 3 years ago I bought a automotive mechanical fuel pump for my ground power. Can't remember, but I believe the one I bought was for a 66/67 Plymouth w/ a 225 slant six. It has worked great until now, but has started to leak and hence needs to be replace. Am I on the right track? Any help will be appreciated. thanks, Dave L.

I think it was like $13 a couple years ago. I bought 2 and keep one in the boat for a spare.
