Review on Wayne PC4 Repair Kit - Model 56671-WYN1 in Black by Justin Garrett

All parts fit perfectly! Except when the motor/pump assembly had a 1/16 inch gap between the housings. Unscrewed the four bolts, primed the pump and let it run for about 20 seconds, it flowed around the large "0" case ring. Now tighten the screws again as they are now loose. repeat this process about three times until the screws are tightened and the space is closed. If you try to fully tighten the bolts at start up, I don't think the engine will spin and you can damage the engine. There are no leaks, the engine runs smooth and pumps about 6 gallons per minute. Rest assured that you are always fueling up! Like new for $17. Wayne has a nice 5 minute video on how to fix a pump.
