I tried using the search function, but it doesn't appear to work...and this has to have been discussed in the past, so please forgive the repeat.....here's the question...Aside from an inline filter placed after the petcock, is the in-tank fuel filter that fits onto the petcock still available? I can't even find a decent part number for the thing...my local cycle shop (dealer for many brands), can get me a new generic petcock/filter assy but $76? I would think this item would still be in production....
