It was a reman pump from Peak Diesel...dam good price for the pump..$800 and the injectors were about $430 each... Funny thing , about the time mine went there was alarge number of diesel pickups (ford dodge and GMC ) going down with injector troubles . I think we got a bad shippment of fuel in the area , but how do you prove it . Grande Prairie is a busy oil and gas area so there are thousands of gallons of fuel being used everyday. Oh and just in case you think $800 was expensive for the CP3 pump...most of the auto parts stores around here wanted $1600 for a reman...and you dont even want to know what the GMC dealers want for one of those ..if they can get it . As far as Vasoline......nope , no vasoline....
