Need Help Identifying Coolant Line

[renovate7]

I have a small coolant line leaking. It is a metalic tube that goes from a manifold on the right side of engine, across front of engine, makes a 90 degree turn and ends above the injector pump. I've been thru the parts manual but am unsure what it is. Can anyone help with a Cummins part number and source. It is in the center of the pic and and is rusty towards the end.

If you go in the -24 under change oil cooler I think they called that line the air compressor coolant line. It has been more than 1 day my memory is gone.

I think your asking about the air compressor coolant line. It can be found in TM9-2320-260-34P-1. Figure 88(that means exploded view # 8

Most likely the part number in the TM is a Cummins number(or will get you a Cummins number if you google the NSN(national stock number).

204898 TUBE,METALLIC MAKE FROM TUBE,P/N 55229​

I googled 204898 cummins tube, http://blkdiesel.en.alibaba.com/pro..._engine_part_204898_tube_cpr_water_inlet.html​

Thanks for the replies. I just went out to JB weld a piece of sheet metal over the pinhole (this is temporary, very temporary) and found a metal tag wrapped around the tube with 3031619 on it. That shows as a good number in the 24P manual. I'm not having any luck crossing it to anything or finding it in a Cummins search.

That number is a Cummins number, but Quikserve Online shows nothing. It most likely supercedes or is NLA. I can't get into the IMS database from home to check supercession.

Wow, thank you. I'll be on the phone tomorrow. If it has a flare fitting on each end can I make one out of copper line?

 

[doghead]

Probably.

If you look at the nut in the TM, then google that NSN or part number, you probably can easily identify what angle flare and make your own. If I was to guess, I'd guess it will be 37 degree(JIC), but thats just a guess.

Edit, I guessed wrong, according to Will's post below.

doghead- you continue to impress.

Nope, It uses a 1/2 in id rubber grommet. The end of the line slips into the fitting and the grommet compresses the line and fitting together. No seal between the line and fitting happens.
