Hello Jimmy & Carol,

The fuel filters for these sytems are usually installed by the RV manufacture and the spin on Garber filter was probably changed out by some shop along the line. I do not know if the R12 see through filter comes with the heater (if you purchase one seperately) but you can change it yourself - the smaller glass see through filters are available from small equipment and truck dealers and are similar to remote engine oil filters- I would want a see through filter assy. to be able to check for contamination/water and since the filter is up-stream from the fuel pump I would install a filter assy. with a water drain the same as diesel engines have- all the coaches I have seen have the R12 see through assy.
