That fuel heater (made by Fleetguard) is the only 6BT part the boys down at Cummins Power South have ever been unable to source for me. I think one of them spent a couple of hours on the phone with Cummins HQ trying to figure out why the part is no longer available -- and he was clearly embarrassed to tell me he could not find it. At the time (a few years ago), Mopar still had them in stock.

There are instructions in the sticky for making a Second Gen fuel heater work on our trucks:

I saw a pretty good argument for this a while ago. The idea being that fuel is more likely to gel in the bottom of the fuel filter and the top mounted heater doesn't do anything to stop that. The other plus side to a 12 volt heater pad is that you could potentially set it up to run off house current for when the truck sits overnight.

 

They come in both varieties....12V or 120V....so depends on how you want it set up. I'd prefer the 12V just in case I have to do a bone cold start, at least the fuel would get warmed up.

 

Do you have a source for these 12V heat pads? Are they made especially for fuel filters or are they generic?

Thanks

I am able to get them through one of our local parts houses....tad pricey, but I have seen them on E-bay and Amazon. They come in all shapes and sizes and watts....just have to do a little homework to figure out which wattage and size would work best for the application you want.

Here's one made for fuel filters already...

Pretty cool, TC. I guess it gets that cold up there to be problematic. Here, I simply start using fuel additives just before the cold weather sets in
So far, so good. Doesn't stay cold here for very long, anymore...

Global warming, or too many hot heads in the state.

 

OK, so yesterday I put a new lift pump on my 89, now it seems the o-ring for the fuel heater started leaking. Don't understand that but, trying to verify. You DO need to get an adapter to remove the fuel heater and just run the filter screwed to the head??? Thanks!

 

The threaded nipple needs to be replaced with a shorter one, as it holds the 1.5" thick heating element in place. Genos is where I bought mine.

Instructions call for green locktite on the threads, but since I never changed mine, I'm not speaking from personally doing it.
