Not sure on how easy or hard the fix would be, but it looks like a compression type or flair fitting on the line side. The fitting where it goes into the pump is an oring base type. See illustrations. Try tightening or take off and look for a crack in the line. If this is the return line, you...

Welcome to TBN! Water cooled I believe? Sounds like a temperature problem, so I would look at bypassing the temp sender or replacing it.

Makes sense as the TC series were fitted with more American standard products like the lighting, like John Deere compacts, being assembled in Georgia.

Welcome to TBN! First off, no need to post the same thing twice, but when you do post, please be more complete in your question. The elbow and grommet on the top of the fuel tank on the JD 4500 is a return line, so there is no pickup tube. The grommet and elbow are available from John Deere...

There is a timing window on the RH side of the bell housing next to the oil pan. Loosen the screw to pivot the cover open to see the flywheel and timing marks. If you have the earlier DPS injection pump, you don't have time it as the injection pump drive gear is keyed to the pump

TDC would be on the compression stroke when both valves are closed and flywheel 0°

It will work even with it leaking. It is the easiest, cheapest thing to check and rule out if it isn't the fuel problem.

Welcome to TBN! Good luck finding cheaper than that or at all. The Massey Ferguson 50E I believe is the predecessor to the Fermec 650, 650B. This outfit shows order for PDF manuals and part: https://machine.market/specification-13728

Mechanical pump it is that. The diaphragm can leak fuel while it is pumping, but not when stopped due to pressure while working

Lift pump just below oil fill and to the right of the battery cutoff.

It is not sleeved from original factory build. It is a parent bored block, no sleeves. Those sleeves are an option, but not the best. I have had regular machine shops bore for oversized pistons or bore oversize and sleeve with a one that has no lip on top. Those shown in the parts book have a...

I agree that those are separate problems and I do believe that the fuel is leaking from the lift/transfer pump, not injector pump. Now that I look at the problem again, I do agree that it is coolant into the combustion chamber. Most likely from a warped head and/or leaking head gasket...
