I’m working a a 2T D4 and after replacing the fuel filters I can’t seem to get the air out of the system to get it to run. Ive seen a special wrench to get the 1/4in bolt head on the back of the individual pumps and was wondering if anyone knows one for sale or any other special tools for a d4

Hi, CodyKroeker.
If you ask your friendly local Cat dealer spare parts man VERY nicely to look in the Classic Cats section of their digital parts listings for such a tool, it may just turn up.
LOTSA things hiding in there that don't show up in the normal listings.
A search on e-bay for "Caterpillar Fuel Injector Pump Bleed Tool' may bring up that jigger too.
Just my 0.02.
You have a wonderful day. Best wishes. Deas Plant.

I looked already I didn’t see any. I know I’ve seen a cat part number somewhere I just can’t remember where I saw it

The modern tool for that is a 1/4" drive oval socket, part number 5P2682, the old style wrench is a 9F22, or 9F0022.

It had never occurred to me over the years that the oval bleeder screws were the same oval profile and size at the top of a common shock absorber. I looked up the A137 part mentioned by cr, and they are available everywhere as shock absorber sockets. I wish I had known that years ago. In a pinch, I used the heavy wire bail off an old milk bucket, and squeezed the round end into an oval in a vise then bent the wire similar to the Cat tool. The bleeders don't take much to turn, and that worked fine for me for many years. Now, I think I'll buy on of those A137 sockets in 1/4" with a universal. Should be a lot handier.

Another huge thanks to CR; I have been on the "Snap-Off" wagon a time or two, and my ex salesperson could never seem to help. If one has the part # it makes life easier! I will order some for the tool boxes. Thx! JM

The A137 is 3/8 drive that is why the Cat socket is 1/4 drive.
Why on earth don't you just use a 3/4 or 19mm open end wrench and loosen the fuel line nuts to bleed air?

I tried to and I wasn’t getting any fuel movement from the pump to where the line goes in or at the injector itself so I wanted to try there to see if I could get fuel somewhere
