I'm trying to replace the prop valve on my 93 Del Sol. Its leaking from the valve itself and one of the fittings going in. I'm having a couple of problems.
And yes im using a line wrench...

2 of the nuts are seized and I've tried everything to get them off. Now they are rounded. I think im going to have to cut the lines and replace the lines and fittings.

Also, The fitting that's leaking looks like it was crossed threaded so im going to replace that line and fitting too.

I'm stuck. I think they sale brake lines at Autozone for $7 but what kind of fitting do I buy to replace the old fittings to go in the new prop valve? I saw double flare but that doesnt look the same.

 

Vice grips will get the fittings out, or a very small pipe wrench. The fittings are just a standard metric tube nut, the flare is just a standard double inverted flare.

 

Double flares aren't too tough to make. A cheap flare tool like Craftsman makes is good enough.

Like 94EG8 said the fittings are standard and are sold at any good parts store. Just bring one in to match it up if there is any doubt on the size(s).

A torch (propane is fine) and vise grips should get those fittings loose.

I like to scrub off any rust with a wire brush, heat it up, then hit it with some penetrating fluid (PB Blaster, Liquid Wrench or even WD-40), and sometimes repeating those steps again before trying to twist them with vise grips.


Good luck, that area is tight I know. Test of patients for sure.

 

Been going at it for awhile now and still no luck. Looks like i may just cut them and replace. Hope all goes well from here.
