Is the large scale DuBro in-line fuel filter sufficient for filtering gas on the plane? Must a felt filter clunk be used even with the DuBro in-line? I have the DuBro on hand, but would have to mail away for the darn Walbro felt filter.

Neoprene vs Tygon in the tank...Tygon seems stiff even new, with a curl in it from the bag. Seems it won't fold forward for nose down attitudes. I guess I want to find some of the neoprene but that means another order for the Hayes brand. Really irritating since I just did a large enough order with Tower for free shipping, and now I find these other needs.

I feel like just trying the DuBro in-line filter only, and the Tygon in the tank with a regular clunk.
