P/S return line question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

i have a 72 3/4 ton 4WD, i belive this is the correct return line for a 72, my steering gear box leaked badly with this line installed. it is the correct thread.

i made up a "O" ring style fitting/tube for it and the leaked stopped, it just looks funny. so it must be a newer steering gear box, 73+?

the question, is there a tube pre-bent just like this with the o-ring style fitting available anywhere?

I really don't know but that's a simple bend. A flaring tool and tubing bender will take care of it easily. You know, it's usually not necessary with flair fittings but since this is low pressure, why not try thread sealer or teflon tape on this one? Maybe you can prevent the leak that way.

the threaded part is not long enough, the nut hits the box before the threads bottoms out, so basically it is tight but loose.
i am going to investigate the gear box, maybe get the right one back on?
i bought this truck not completed or with a engine. there is just a few odds and ends needed attention.
i have lots of time.

it has a nice little motor in it now.
