My front cover is leaking and I can see from below that there is a weld repair on the cover which is near the leak. I found a source called Car City Engine and Machine (Florida) and the brand is PAI which interchanges with Cummins p/n 3936256 for the inline pump (p7100). My question is, has anyone heard of this brand/outfit? If it was an internal part I wouldn't touch it but for $129. 00 brand new I'm tempted to buy it. Any input??
