Cool Hose Clamps Needed - Inquire Within

[Duck-Stew]

Yeah, I found a fix for it.  I'm converting the bike *back* to carburation.  Voila!  Problem solved....  (albiet about the longest-way-around that could be found, but that's me for ya)

The problem is also due to the quality of the OEM rubber (or the lack thereof) and the tight bends in the fuel system. You can improve it by using heavy duty fuel line (I think I went to some Michelin stuff, it was much thicker and heavier than the old lines and it has held up well. Some people switch to Harley stainless steel lines for indefinite life) and carefully cutting them to a length that minimizes the stress on the bend. The first time on mine it split next to the clamp, the second time was along the bend and the fuel filter split in half along the pressed seam in sympathy.

Generally you shouldn't have to replace the fuel lines for at least several years, sometimes indefinitely - on everything except an old Duc. On those it's recommended you swap the lines and filter every 6-12K (also because the tank liner flakes, clogs the filter, and overstresses the fuel pump - which in turn overloads the fragile electrics and burns out the wiring as well as the pump. It's an amazing daisy-chain of mediocre parts that affect each other in turn).

It's not necessarily all t-bolt clamps that do this, the Duc ones just seem to have a habit of cutting into the lines if they are too tight. And if they aren't tight enough, the line blows off completely (happened on a friend's ST4S).
