Just finished my annual condition inspection. What follows is a bit of a rant about Earls tubular fuel filters....

Basically they're just a 1 inch diameter tube of aluminum about 3 inches long threaded at each end and with a filter in the tube. They're a pretty blue color with male AN fittings at each end. The problem is that the central tube doesn't have a nut on it, so you undo whichever end comes undone first, then have to put the tube in a vice to get the other end off.
1 out of 10 for design.
