Thanks for the advice. It's got me thinking that the prefilter/heater is trouble waiting to happen. It's not that cold here anyhow.CToney said:After you try and change it you will wish you got rid of it. Its hard to get at and you tend to get covered in diesel if you are not careful. The inline fuel filter is the same filter used on our tractor w/ a 5. 9l cummins and some w/ 8. 3l and p7100 pumps. The rubber hose going from the fuel heater to the lift pump will sometimes leak air for low hp, poor mpg, smoke and hard starting. Get rid of it all and solve a lot of problems before they start. The fuel heater doesn't do much good anyways just another part to fail. I just look at other heavy equipment and then at the crap that dodge put on these trucks and shake my head sometimes. Do a search and you'll find more guys with a similar opinion.
Thanks,
