Ford 3910 Injector Pump Leak

[Texasmark]

THAT is the fuel INLET line & it SHOULD HAVE a brass ferrule on the end of it.. the nut tightens up on the ferrule & seals at the bottom of the inlet nut..
Look closely inside the PUMP inlet, you'll see it..if its still there..
You'll prob. have to dig it out w/ a scribe..
Once u find it, see if u can put it back on the line.. IF YES, just push down on the line when your tightening it up..
U might have to cut the line some, to get a good clean sealing surface again..
They sell ferrules at Home Depot or Slowes.. .15 & your back in business.. Good luck.

Basic "compression" fitting. Usually the ring crimps once, works, and locks onto the line. Since the ferrule came off, check the hose at the end, where the ferrule should be and see if it's kinked...from the ferrule being properly pressed into the hose. If not, just do as pumpguy said and put the nut on the tube, slide the ferrule carefully back up the hose to the bend, or up ½" for a number then ensuring that male and female parts of the interface are clean, as he said, push the hose all the way down till it stops, holding it there, grasp the nut and bring it down on the threads and tighten it up forcing the ferrule to cut into the hose and hold pressure.

On torque, I pull it down good and snug and then pull on the hose to ensure it's seated. Too much torque and the ferrule can cut through the hose which you don't want, or not seat properly......not enough and the pipe will leak/come out.....like it did. Expect a sharp resistance while tightening for your time to stop turning.

If the like is kinked where it once rode, get the new ferrule and cut the pipe off just enough to have smooth pipe for seating the new ferrule.
