the fuse is in the dash behind the door. Very top one should be a 30 amp circuit breaker. They are available at Napa and maybe others. A glass fuse will work but not recommended.

Is the ignition on? The compressor circuit only has power when the key is on.

Pressure switch that is/was on the tank?
I don't have a diagram in front of me, so it's a SWAG...

""

Are you sure the fuse is actually making contact in the clips? Sometimes those glass fuses have continuity but are not contacting in the clips.

Bill,

Did you check for a ground? There should be a black wire on the pump connector, check to make sure you have low resistance to ground, >1 ohm. If the ground is good than check for power at the pressure switch
