Have customer with problems with propane vaporise rs.

Claims that it is the propane I am selling him. Highly unlikely . Stain tests were done with supplier and were O.K. Sell a lot of propane to customers with propane powered forklifts. No other problems. Seems peculiar only with new toyota forklifts. Have not seen system like these before . Has something to do with the new emission standards and the way regulators are installed. Know that propane does contain oil and will leave residue over time. He describes a tar buildup in vaporise rs > I would ume that is oil. Claims that heat on vaporiser is causing this to occur
