My fuel heater got to leaking around the gasket, so in the prosess, I damaged it while trying to do the two locknuts system to remove the
stud and somehow damaged the fuel heater itself.
I would like to do away with the heater completlely.
Can I machine about 1/4 inch off the end that screws into the intake manifold?

Has anyone done this?

Thanks, Tom

Best is to go to CUMMINs and get the correct fuel-filter stud that is made to be used when the heater is eliminated.


I deleted the fuel-heater on my truck and haven't missed it since.

Before, a couple of times, it followed the fuel-filter off when trying to change a filter.

I didn't need this aggravation out on the side of the road somewhere, so I just got rid of it.



Another option is to by-pass the stock fuel-filter completely and route the fuel through a remote-mount filter located in a more easily accessible position.

 

And, by the way, just so others who might read this will know better :


The fuel-filter stud is made in either of two configurations.

One type is notched, or slotted if you will, such that a very wide screw-driver-type blade is used to remove/install it.

I re-ground one of those hexagonal cold-chisels into a dedicated tool for use on that type, using the appropriate sized wrench on the hex shank.


The other type is hexagonally bored and a very large common Allen-wrench is inserted in this hex bore to remove/install the stud.

 

How did Cummins charge for the stud?

 

The correct part-number should be floating around amongst the threads somewhere, as this has been discussed a lot; it may even be in the "sticky".


It has been a while; but, I am thinking something less than twenty-bucks.
