H83 Heater Fuel Filter

[Capt-klumb]

Hello. I recently purchased an H83 diesel heater and got it running. During my troubleshooting I opened up the fuel filter and cleaned things up a bit. My only question is if there is supposed to be a traditional disposable fuel filter within the assembly. Per the IPC TM, it does not mention any disposable filter, only the whole assembly. The maintenance manual TM doesn’t really call out a specific filter either, but it sort of indicates there is supposed tobhen I open up the filter bowl there’s just a small copper colored cylinder descending from the head of the unit, about 0.5x1in.

Has anyone encountered this, know of a P/N, or if there’s even supposed to be a disposable filter?

your help is appreciated.

This is an interesting question. I hope you downloaded your TM's from the Heater TM forum here in SS. The parts manual has the latest change, and that's a good thing. But your problem is that the parts TM is not showing the filter for the filter housing. And yes, the filter is changeable. Pull out the copper cylinder. That's probably the filter. Clean it. use something that will eat off the fuel lacquer. Soak it a while. Put it back in. Look at the filter to see if there is a part number on it. Maybe even post a picture here. I will ask someone if he knows why the filter was omitted from the parts TM.

Is this what you are looking at? The screw in filter is part number F2X79T3, NSN: 2910-00-652-4446

This is normaly not something that gets replaced, but just cleaned. Still, it should be in the TM. But its not.

i have not seen a replaceable filter in any of the ones i worked on, only the brass stacked washers. I have also found the gaskets have been a weak point and suck air, and the other weak point is the valve for inboard fuel or external fuel sucking air. I also replaced almost every oem filter with a spin on filter and filter head.
