Well.. this regulator had 258Kmi on it and while it did sit for 6 years unused that was from 82-88 and its been in use since then. It failed on my return trip from ND in the summer and in the heat. It allowed the pressure to go up to 45PSI on startup at times and never kept the pressure steady. this made starting hard as it flooded and I had to clear it with the pedal floored while cranking. I replaced it with a spare and all returned to normal.. I have a pressure guage on the console to keep an eye on all this! Yea jim.. when you get around to it send it back.. I thought it was just a can and a couple parts too. thanks!
