I can't believe I don't know this... here goes. I want to hook up my can of diesel purge to my supply and return line to and from the injection pump. which one is supply and which is return? i have one toward the drivers side and one toward the passenger side. which is which? Thanks
Ha ha... it actually doesn't matter much in the end since you just feed both ends into the can of dieselpurge and start 'er up.

Having said that, the input is on the passenger side of the pump and the output is on the driver's side. Some people run a cheapo gas-line filter on the input side... probably not a bad idea.
Thanks Vince. I am planning on an inline filter just because it get pretty dirty on the return. When we do Benz' they already have the pre-filter there so I use it and then replace it when I'm done. Not the case on my VW. Thanks again. Trent
Good man... let us know how she runs when you're done.

just got the purge done. I had been having some slow start ups. Now I will let it cool and restart later to see if it helped. I'll let you all know.
