LB7 Injector removal

Does anyone have an injector removal tool they would sell? Or does anyone have an alternate way to remove them?

Twist them with your hand and pull. If they do not come out that way, use a heal prybar and pry them out. BE CAREFUL because if they are stuck, it could pull the cup out with it.

I have had luck with just twisting with my hand and pulling them out carefully watching the cup.

There is a tool, Merchant sells it, others may but I do not know, but most use the heel prybar. I bought the prybar just in case but have not needed it yet. and hopefully WON'T!!!!

If you take a high pressure line and screw it to the injector you can pull and wiggle the injector better and it will come out. Do not bend the line just use it enough to give better leverage. A mechanic told me that often when he used a removal tool he pulled the cup as well. I tried the line tip and had good results.

I brought 3 new ones with me when I had mine done. The VERY LAST ONE was the only one that came out. Glad I had a new one standing by with O-rings.

Use a punch the size of the injector hold down bolt, stick it in the bolt hole, and pull away from the injector. This should pry the injector right out if you cannot get them out by hand.

I have never used the injector puller tool, but I understand that it works the same way.

There's a number of ways to pull out the injectors, and a few tools to try. Here's the ones I know of:


Pull directly on injector:
- by hand
- with channel locks
- with something threaded on (like the HP or return line)

Pry the clamp up from underneath
- with a heel bar
- after I did mine, I found a couple small flat bars at home depot that might be perfect:
tiny one
larger one

Pry on clamp, using the hole for the hold-down bolt
- with the expensive special tool
- with punch, socket, or anything else the right diameter (I found a deep 1/4" drive socket that fit nicely, and could pop out some of the easier injectors with just this and a 1/4" breaker bar)

Just did mine, my technique was to put the return line bolt back in it's hole after the return line was removed, and put a high pressure line on, then use those two to twist the injector back and forth, spray some WD40 on it, twist some more, repeat until you can lift it out of the hole. They all came out without pulling the cups.

I did the right side, I had to use the heel bar, had 3 cups come out, but 6 new seals from the dealer a tube of red Loctite, and some cleaning and all went back in easy as pie!

Heel bar is the way to go, just make sure you drain your coolant below the cup level, or you will have to suck the coolant out with a tube taped to the end of a shop vac....I know.
