Help! Power steering line leaks

Just did the H1 hummer steering box upgrade, and the power steering lines that thread into the steering box are leaking in-between the nut and the line. I've tried Teflon tape on the threads and tightening it down really tight. So I don't know if it doesn't have a good seal between the flare and the nut or what, but I'm getting quite frustrated with it. So any advice would be greatly appreciated. Thanks!

There are 2 different types of lines used on CJ's. '76 thru 79 or 80 IIRC used a flare on the fittings. From there up to '86 they used a o-ring type. Not sure on this, I'm guessing the H1 box uses the Oring ( I haven't seen one)
What fittings do you have on your Jeep?

Any '80 and up box uses metric o-ring fittings. That's the problem. Hopefully you didn't damage the threads on the box threading SAE lines into them.

They threaded in fine, they just leak in-between the line and the nut.

They may have threaded in ok, but they aren't the right part for the job. That's why you have a leak. You can either have a custom pressure hose with metric o-rings at the box end and SAE inverted flare at the pump, or just swap out the fittings on the pump to metric oring and stick with a standard o-ring hose for any '80 and up CJ.

Just go down to the parts store and get a set of power steering lines for a 80 and up CJ7. They will have the correct ends.

Beat it to fit, paint it to match!

At the pump end they won't be correct.

The pump end will match the style of fitting on the steering gear. They don't make a hose with a flair end on one and o-ring on the other. I just purchased a new set for mine. My Jeep also has a H1 box on it. The lines bolted up perfectly.

Yours is a 1982, the OP's is a '79. His pump has the flared fitting.
OP, do what CSP said, swap the fitting on your pump to the o-ring style, and get a new Oring style line.

Yea, I forgot about the age of his pump. The easiest way is to change the pressure union to the newer style. I know a new pump is not that much either, so you may be better off just replacing the pump with a new one.

Reiterating what's been described (in dribs and drabs) above -

IIRC the GM pump just has an added fitting to use the o-ring connection. You can get one from a steering pump at the pick-a-part. Then use the o-ring style hoses ('80 up?) that now match the gear and the pump.

Or, have your local hydraulic shop make a replacement hose with o-ring fittings on the gear end, and a flare nut on the high-pressure pump end.

1) '77 J10 LWB, 258/T15/D20/3.54 bone stock, low options (delete radio), PS, hubcaps. 2) '82 J20 360/T18/NP208/3.73, KOs, 7600 GVWR 3) '75 CJ-6, 304/T15, PS, BFG KM2s, soft top 4) '95 VW Golf Sport 2000cc 2D

Thanks guys for the advice! I'll go down a hydraulic shop some time this week and have them ether make me some new lines, or weld a fitting on my old lines.
