Trying to flush out the AC coil from the firewall, got the solvent in
there with a flush gun, but seems hard to get the solvent out. Am I
going about this wrong?
Using a craftsman 33 gal compressor, delivers 6.4 scfm at 90 psi.
Cranking that up to 140 psi and letting it rip. Still seeing drips and
spittle coming out of the bottom tube of the AC coil (wet/dry flushing
in reverse direction of ac flow). Seems like there is no end to it the
residual solvent trapped in the ac coil.
Am I going about this wrong or is it just a matter of having more
