Compressor will not build pressure after replacing V-pump with a new unit.
I replaced the V type pump with a new unit after the old one seized. It came with a pipe connecting one head to the other.
However the output was on the wrong size so I switched the L fitting to the other side.
Is there something special about these tubes as far as the direction of air flow? The pump sucks in air through both filters, but builds no pressure at all.
