1987/1993/1996 Bronco AC upgrade...

[slawson2000]

If I replace the valve with a HPCO, I kill two birds with one stone.

What AN fitting would it be to adapt a HPCO?

Unscrew that HPCO switch from the adapter & see what the thread & seal size are.

[slawson2000]

The HPCO and HPRV are the same threads. The problem is that this switch is too wide and will not fit behind the compressor. I either need to find one that is narrower or some sort of adapter/spacer that will put the wide part out past the compressor. Does that make sense?
