Scott I think they want a 1/2 fitting for the return line. I will call them again. I could
weld a bung on that angled piece off the top of the tank so I will check with Fass
to find out if the return could be in the diesel when the tank is full. I would also like
to pull the return line without dropping line cover in the main storage area.

My turn with the 300200 it appears.  I changed the spin on filter next to this and purposely didn't touch this guy, and now it's leaking.  Ordered a new one online.  I read somewhere about removing the thumb screw to remove this...does someone have the link?

If you reused the old fittings, that may be the issue...I reused mine and it was a stupid mistake. If you score (even in the slightest) the old fittings and reuse them they WILL allow air in the lines. I had to replace them after so I got new fittings and added clamps to boot. Sorry you are having an issue and I know it is the last thing you want to do over but I have had no issues since I did the fix. Good luck.

I didn't touch the 300200 plastic see-thru assembly, but it is leaking now, so I've ordered a replacement.  Just need to figure out how to remove and replace it properly.

Keith,

You may just need to replace the O rings in the filter you have.

As I have written before I believe if you replace that old system with a Parker/Racor 790R30 your problems will be solved. That's what I did and it solved mine.

Thanks Mike...didn't want to take the chance of taking it apart and having an issue, so a new one is on the way.  I've not had issues until I replaced the spin on filter next to it last night.

DJ, I've seen your info as well but I'm hoping this $65 fix works.  I've not had an issue with this previously and would rather not spend another $400 on the coach right now.

I understand your reluctance to spend additional money on this but (for me at least) it was worth it to resolve a recurring problem and to avoid (once again) being stranded in a remote location. Good luck!

Take the wingnut off the top and lift the housing up to get to the filter. It is cleanable but if cracked has to be replaced.

There are O rings on both ends of the plastic filter, easy to replace.

There are 2 o rings for each end of the plastic filter. One on each end is visible but the other ones are inside the housing.
