What us this line. It's leaking at the fitting.

A part number would be great
My finger is on the fitting that leaks

Tee fitting that you have your finger on is on the fuel return line that leads back to "top of fuel tank". I think I located the correct seal(item 3) part # R51936 if your tractors serial range resembles SN in photo below. Seal on top of injector is part #R79605. Item 1 in 2nd phot is fuel return line to tank.

Welcome again to TBN

If Tx Jim has helped as it looks like he has, will you respond with what you do with that help? Tx Jim is a great resource for JD folk on TBN, as he has a lot of real experience and knowledge.

You did not give a response to your 2018 quest for help. Always nice to hear back as it helps others who may have a similar problem.

I'm not one to bail after starting a topic on a forum.
I'll take your word for it if you're saying I did that on here 7 years ago...
Something must have come up that distracted me from the forum.


I will be looking into his response to me as soon as I can get to the machine. (Around 4:30 p.m. EST)

At that point I will re-engage in this thread.

Hopefully you can see it.

This ends in a "T" so Im not sure this is the correct serial number...

It is on the engine. Right side.


Upon further review of the line it does indeed go to the top of the tank.

Thank you much for the ACCURATE and quick response !!!!!!

Thx for that.

By that serial number on the engine do you think the part# you presented will work?

Thx

Sorry I forgot that the thread I posted listed engine serial # range. Yes I think part #s I posted should fit your tractors fuel system.
