Mack Technician Posted October 12, 2017 Share Posted October 12, 2017 (edited) Critically......Guy at work has one on his pick-up. I figured He ran out of stuff to buy. As long as your fuel pressure never falls under spec your golden and horses are well fed. If you pop your cap on the Mack you can see aeration occurring as fuel sky drops into main column. If you run low fuel level in tank you might pull fine air bubbles. i, personally, would spend the money on converting drivetrain to synthetic, good tune up, taking baby girl to Applebee's, etc. Edited October 12, 2017 by Mack Technician Quote Link to comment Share on other sites More sharing options...
