Hey guys
I’m going to pull my injectors. On my 1FZ with 350,000 to have them cleaned and flow matched I was wondering “since I’m in there” if I remove the upper and lower intake if it would be easy to replace the following:

Pesky Hester Hose (from the top down)
Fuel Filter
Have upper and lower intake hot dipped
Injector harness
Upper engine harness

Any other recommendations?


(I just did a full tune up with rocker cover gasket)


Thanks!
 
Yes it would be easy to replace the PHH, fuel filter, and injector connectors.

Not sure what you are trying to do with the "upper engine harness".

Depending on what state your in, you might want to delete your EGR.

Also buy an additional banjo bolt and washers for the fuel rail.

California EGR is a must for registration
 
I'm pulling my injectors also soon. I'm at 220,xxx miles and while I'm not having a problem, I'm doing some baselining. Since I'm going to be in there, I might as well do it, right?

My buddy has a 2000 Disco2 and pulled the FI's (and the intake manifold to have it blown out) and ONE of his injectors was around 60% while the others were running between 35% - 40%. I know...way different vehicles, but I figured, why not.

Since I'll be in there.

;)

Yes







Sounds like a good list.

Replace the injector harness clips that go into the injector at very least. They are a few cents each, and get very brittle

Hopefully they are still available, I’ll add them to the list

My memory had them around $1 each. Guess I was not quite right, but not far off
