Excellent idea. I think I can work with that, so I may just use the glass filter. At least there's a chance I can place it so it's in view when I get in the plane. That should help avoid the risk of it getting completely clogged before I detect it.

Charlie,

I put safety wire on my glass filter joining the two end caps. It doesn't prevent them from turning but it prevents them from getting further apart, which would eventually stop them from turning.=C2=A0

Thanks Bill, but I wouldn't just have to come out of retirement; I'd need another whole career. :-)

With an RV, the lowest points in the fuel system are the sumps on the tanks, so water separation would be redundant. And I just can't make myself pay $200-$400 for a fuel filter.

My biggest misgivings about the little $10 glass body filters are the somewhat limited filter area (but still better than some of the 'racing' fil= ters that have a little 3/8" disc), and the fact that they screw together with no easy way to safety them from unscrewing. The latter is more paranoia than a real issue; I've been running one for years on the Lyc with no issues. One thing I do like is the ability to actually see any trash accumulation.

Thanks,

Charlie

What's being used for the ~100 micron pre-filter feeding your Walbros? I'm running one of those glass body cylindrical models on my Lyc powered RV, and it's been fine, but I'm open = to better options as long as I don't have to come out of retirement to afford them.
