My experience with Advanced Powerplant Solutions so far is... terrible.
Placed an order with them for a 914 oil temperature sender on May 2, with 2-day freight.
Never showed up... on May 9 I finally got through to a real person over there and they promised to send it out immediately on 2-day freight.
May 13, still not here.
No one is responding to phone messages. No one is responding to e-mail.
But... they did charge my credit card, so that's something!
Never again.
