I'm going to get the fuel heater o-ring done on my truck soon. There was a post recently with some part numbers but I can't find it. Even went back 12 pages. Anyone have them?

Can the rear transmission seal be changed without tearing the transmission apart? I know on a 4x4 half-ton you can change it in the truck, but don't know about these.

Plan is to drop the trans and do the rear main, too.

 

fuel filter gasket:
fleetguard:3834185-s
for boi diesel:3958485-s
cummins:3913695
dodge:4429695
napa:1036(will work but thicker)

 

Thanks, the 1036 is an oil filter, use the gasket and toss it, right?

 

yes, the napa 1036 is an oil filter.i just use the gasket.they are only about $6.50.i never had any problem with this gasket.but, i don't run bio.i run diesel in winter and french fry oil in summer.

 

The counter guy at NAPA looked at me funny when I told him I don't know what it fits, but I need it. He said GM. I told him the O-ring will fit the fuel heater on a Cummins, too. Said he never heard that.

 

let me know if it fits.it should.that was the number i had written down last time i changed a gasket.it's be a while.i couldn't get to the cummins dealer so i measured filter gaskets and that's what i came up with.

 

You're not the only one who has put that number out here. I was going to do the heater today. While we were breaking ice I noticed I had some slush freeze to my insulated jeans. Screw that, it's cold out there.

 

do you really think it's necessary to have a fuel heater? it doesn't get real cold in southeastern pa.maybe 10 a couple times a year.i have one truck with a heater and one without.doesn't seem to make a difference.they both start and run in cold weather.i don't think any industrial or ag engines use them.seems like just automotive.i have a new heater on the shelf from geno's and never put it on the truck without the heater.what do you think?
