I’m trying to figure out where this hose goes. When the engine is running it squirts out what looks to be like coolant to me. I’m not finding any loose random hose that is not connected to something, that I should hook it up to.

If you are referring to what I have pointed to in the picture, that would be what should be a plug for the last fuel injector--- the plug (a slug of metal crammed into the end of the piece of hose) appears to be missing---(since there is no 6th fuel injector). What is squirting out is diesel fuel.


The part (referred to as a "Diesel End Plug" by Pelican Parts):

Incidentally, it is common (and a good idea) for those of us driving these vehicles to keep a spare plug in the vehicle in case the one currently installed fails.

Exactly it should be plugged and what you see squirting out is diesel and not coolant

Thank you! I pushed a screw in there hoping that works until the plug arrives in the mail. I just moved 900 miles and towed my 83 behind a uhaul, so it is my everyday driver at the moment.

Steven,

The rest of the black cloth braided return lines on the injectors fail also. You may want to order 1 meter of the return line and replace yours. Easy to replace, no clamps used, just push on.

Good luck!!!

A nail which fits tight is fine. When I first saw the OE plug, I thought some gomer had just stuck a nail in. The proper plug is actually more elegant, with a little groove to aid retaining. There is minimal pressure there, as they connect to the main fuel filter which runs at the lift-pump pressure (inlet to injection pump), around 10 psig. Those collect the fuel which leaks past the metal-metal gaps in the injectors. I switched to Viton hose (1/8" recall) maybe 10 years ago for those and never had any more weeping of fuel around the injectors. I still use the woven rubber hose for the one long run, just to use up the stock I have, and it lasts longer since away from the engine heat.

You also want to keep fuel filters and tools to change them in the car (always - no exceptions).
