I don't believe the TruFilter is disposable
I had a similar type of filter on me old dodge big block Gasser truck. It consisted of a SS mesh screen between two cast alum plates with fittings in them. You un-bolted the two plates, removed the screen, cleaned it, then re-installed the screen and bolted the plates together. I used it for about 60K, and did not have any problems with it or the engine. I worked the truck hard, often grossing 18K going between Arkansas and California. The last such trip I made with it I had 135K on the truck and even though it wasn't the fastest rig on the toad, it never faltered and I managed to get about 7 mpg. Empty, I regularly got 14 to 15 mpg. These are hand calculated figures, since this was way before computers
