I guess the price has gone up in the 8 years since I bought mine. Consider running 2 stroke oil in the fuel, we have low sulfur diesel here 500 ppm, you have ultra low there, less than 15 ppm, which will not lubricate the IP. Politicians and greenies are really nice to the poor people!!! The pesos have been gaining value over the USD. Not all rebuilds are equal, I am happy with the one from Pensacola Fuel, which is well known, although the guy I talked to, sounded bottom of the class. When mine had the problem, I didn't think about the large return from the IP to the tank, just thought the filter failed, it all makes sense now. I hope you have a spare vehicle while you wait. I keep 2 spares.
