4720 Fuel Leaking from Filter Primer

HobbleCreek · Apr 27, 2020

I have fuel leaking out (practically running out) from above my fuel filter. It's coming out around the fuel filter primer pump. I'm planning to replace the fuel filter today, but will that do the job or are there other seals in that fuel pump assembly that I need to look at replacing?

I have to thank TBN for the "Similar Threads" feature that showed up below my post. It came up with this thread: https://www.tractorbynet.com/forums...rating/379895-4720-fuel-primer-pump-leak.html

Looks like I'll be needing to replace the entire assembly.

Well, I guess this thread will be more like a journal entry. My "local" (40 minutes away) JD dealer had the part in stock. The primer assembly included a new filter for under $61 including state sales tax. Just the removal of two bolts and a hose on each side, opened the bleeder valve, pumped the primer until fuel spewed from the bleeder valve, tightened the valve and pumped a few more times. Started up immediately. No leaks, no fuss, just a little muss.
