i was just over at a friends house helping shave his tailgate...there was a blitz 337 comp on his workbench and i asked why it was there. he said that he had it on his truck for a while, but when the tank was full, air would come back out the intake on the compressor. i dont know if he was running a check valve or not, but he said i could have the comp and use it if i could fix it. would not running a check valve be the only reason the air would leak back out the intake?
