What in the heck is this?

Ive been having a problem with my truck for a couple of weeks now. I have an inline filter and went to change it monday when i found a brown resin like film cloggining the fhe filter. I have no doubt it is in my tank and clogging the inlet. My question is what is it and how do i get rid of it?

I'm guessing you are talking about an inline fuel filter? This is pretty common in a fuel filter that hasn't been changed in a LONG time.

Id start with a new filter (obviously) and put some fuel treatment in your tank for a while when you fill up.

It is an inline filter, but it has only been on there about 6000 miles. It was like an epoxy that spilled and dried, but the diesel itself was clean. As far as treatment i use diesel kleen

I wonder if it wasn't a glue within the filter that the diesel broke down? That seems really weird to me though... Is it an aftermarket inline filter?
