When I originally put the jumper valve together it had compression fittings. I installed it like that, but have since taken it all apart and redone it with 45* double flare fittings that I got from Sears Hardware (of all places).
Here's what I used:
- Two (2) 1/4" MALE t-fittings for splicing into the brake lines.
- Two (2) 3/8" to 1/4" adapters for the jumper valve to brake line connection
- Eight (8) 1/4" FEMALE nuts for joining it all together.
Note: There are also SAE 45* fittings made. They may be made of another stronger material besides brass, but I couldn't find them anywhere.
I placed the jumper valve on the frame under the powermaster unit. I also know someone who places their jumper valve between the frame under the drivers door. They drill a hole and mount the valve there with a bolt. I would of done it that way, except I had already started the job and had lines cut.
Hope this helps. If you haven't started the job yet, DON'T. Pay someone else for this headache!! I will NEVER do that job again, and I did it with the engine out of the car! I read somewhere else on this board where someone was quoting about 1-2hrs to do the job. I'd think 2+hrs (without a lift) if you were using compression fittings (don't have to flare the lines), but to do it with double flared lines... that's bull! Plan on 4+hrs
