There is nothing more fun than resurrecting an old post.
I think this conversation about fuel filters deserved a comment.
I have lost 2 birds to dirt.
The first was a Cap 21 with dirt in the filter screen that made the forced go around end badly and the second was a Cap232 to dirt choking off the fuel flow at the filter just as I pulled up hard at very low speed. I hate eating aircraft to stupid things partly because they simply don't taste good.
Since the second, I have started using automotive filters before the engine because they are large enough not to totally fail catastrophically and do a great job of cleaning the garbage out of the fuel. Oh, I think it is a Chevrolet Chevette filter and I simply tie wraped it to the firewall standing up. The only noticeable thing was sometimes the first run took about 2 minutes before the filter was full of gas and that made some of the wilder maneuvers problematical since the engine tended to stall when the airframe was inverted with G loads too early. In other installations I have found putting the filter on its side solved that issue. The only issue you might have to solve is the fuel line size to the filter port size, but that shouldn't be a show stopper as they do make reducers.
YMMV
