DADS is right on. Also I use WIX 33033 at O'Reilly's, it has 3/8 barbs. Hardware store brass adapter or McMaster Carr has 4860k611 metric (BSPT) to NPT (SAE) adapter $7. male/male. That one is 1/8, you need to find out what size metric the tank has, then buy an adapter, then get a NPT to Barb, then a fuel valve, a valve that has barbs on each end will work between two hoses. Don't know why you need a valve anyway. I just squeeze the rubber hose with locking pliers if you need to do something on tank or drain it. To recap: McMaster adapter to tank, NPTF-barb fitting on adapter, bulk rubber fuel hose on barb down thru hole in cab to beginning of hard line that is clamped to frame.(pull nut back and clamp) If you want a valve, put inline with rubber. (Fuel valve with barb-barb, motorcycle shop, marine supply, lawnmower shop, auto parts store). Plumb in your canister filter between two hard line sections or at carb with the hoses and clamps that come with the WIX 3/8 barb or the Autozone 5/16 barb. Sound OK DADS? P.S. I love McMaster Carr because you can download a 2D CAD .pdf drawing of their parts for free, sometimes a 3D. then you can really "go figure".
