Replacing diesel injector nozzles and testing on Ford 4000 engine 

Injectors were the original ones out of a 172ci 4 cylinder diesel. Pop off pressure is 2750 psi.

The metal line came with the injector tester. It has another one too.

@@chickenhousemechanic Thanks for the replay, i hope the pressure test set i ordered fits my ford 3000 injectors as it is.

@@karlandrefrantzen6709 you're welcome. Going off memory I want to say the tester I bought came with a 14mm and 12mm adaptor. Can't remember the thread pitch though. Kinda coarse, maybe a 1.5mm thread pitch.

@@chickenhousemechanic Mine comes with 3 adaptors but i would think that the threads on the injectors are in inches so lets see if the kit will fit when yours is metric

I looked through my papers and spreadsheet and I apparently didn't write it down. Most likely I bought them from Just8ns.com. Part number for the 1958-1964 injectors is C5NE9E527A.

@@chickenhousemechanic thank you I'm rebuilding my 63 4000 industrial and your videos have been a great help along with the manual

@@jeremyhastings8413 glad to hear that. I try to make the videos thorough without being too boring. The manual is a great help too.

Isn’t it a 4 cylinder?

Where did you get..?

From what I understand it is a way to relieve pressure to the injection. Others online have said the tool leaks if you loosen it so I just left mine tight and relieved pressure by cracking the line fitting at the injector.

@@chickenhousemechanic but for pop testing how should I set the jnob

@@kubaSWAT had mine turned all the way in so the pressure didn't bleed off.

@@chickenhousemechanic got it thanks, and the tester doesnt leak ??

@@kubaSWAT nope. Kinda surprised at that honestly.

As far as I know these injectors do not have any pre injection. Service manual doesn't mention anything either.
