Fuel injection lines???

What happened to the headlights??

Yes, I recommend that you remove the hard lines when doing glow plugs. It takes about 10 minutes and your hands will thank you for it.

A couple of caveats:

1) Don't overtighten the nuts when you reinstall. They don't need much torque to seal and most folks go crazy with too much torque.

2) Don't even think of using a wrench to reinstall until you've started the nuts by hand and are positive that they are started. If they don't line up........bend them into place before starting the nut. Tighten the nuts on the IP first and then install and tighten the nuts on the injectors.

3) When you go to start it, there will be no fuel in the lines. Mash you right foot on the floor and hold the key in the start position. It should start within 15 seconds.

4) Cover the outlet ports on the IP when the lines are off. You don't want any foreign material dropping in there. It will plug the injectors for sure.


Leaving the ignition switch on will not cause glow plug failure. The plugs shut down after about 35 seconds or as soon as you turn the key to the start position.
