Cub 5252 fuel trouble...

I recommend you look up your engine label information on the Parts Tree website. A have had too many issues with Amazon parts. eBay is also a good source, but look for genuine parts
 
Thanks guys. I was thinking OEM would be better, after reading reviews on Amazon. People saying parts didn't fit properly.

Looking for some info on my 5252 Cub . Has an electric fuel pump, it seems to run continuesly and floods the engine. Shouldn't the floats close the needle to seat and stop the pump?

I have a 1974 Gravely 812. I replaced my 2ed OEM pump years ago & doubt if I'll ever find another if & when this one goes. My plan is to "probably" to look into a small PSI electric pump & if needed put an adjustable fuel pressure regulator of some type on it.
 
This morning before ordering a rebuild kit I thought I should just take a chance and pull the float bowl cover and see whats going on. Good thing I did. Turns out it had what looked to be a tiny piece of spaghetti stuck in the seat. I think it was a piece of grass. The original owner must have been sloppy putting fuel in the tank and got some crap in the fuel tank probably wrecking the pump. It looks to have been replaced possibly. He also installed an inline fuel filter between the fuel tank and the pump but deleted the one near the valve cover. So after cleaning out the carb and blowing out the fuel line I scrapped his inline tube and replaced it with a second fuel filter, now she runs smooth as butter. I hope it continues to run this smooth. Thanks for your input guys.
 
No. Float

No. Float/Needle just regulates flow depending on the fuel pressure. If pressure is too high it overpowers the Float/Needle. 1 psi is enough. Little electronic pumps can run continuously.
 
Garbage stuck in the seat was the flooding problem. And you are correct, that little pump just keeps clunking along. But she's working now.
