Vic Posted July 9 Report Share Posted July 9 I have a gas line I need to replace from the gascolator to the supply side of the fuel pump. It parts diagram say to use a band it clamp? I was going to use 15.7mm otiker clamps for this. Is there any reason they use otkier clamps for the fuel shut off value but not here? I also see they use worm gears on the fuel pump, so the clamps used differ all over the fuel system. Quote Link to comment Share on other sites More sharing options...
Tom Baker Posted July 9 Report Share Posted July 9 Use the Oetiker on both ends of the line. The only places I use Band-its on fuel lines is on banjo fittings. This is because you have limited space to properly install the Band-it on the fire sleeve. In the Rotax bulletin for the new style fuel pump they show using Oetiker clamps for both the hose and the fire sleeve.

Roger Lee Posted July 9 Report Share Posted July 9 I use Oetiker’s on all fuel lines and Band-It clamps on all fire sleeve. Quote Link to comment Share on other sites More sharing options...
FlyingMonkey Posted July 10 Report Share Posted July 10 Tom do you use two Oetikers, one on the line and a larger one on the firesleeve? Before I swiitched to AN fittings I used Oetikers everywhere, usually using two as I described. You just have to be careful to not put the firesleeve Oetiker directly over the line clamp or you'll never get a good seal. Quote Link to comment Share on other sites More sharing options...

I just know that back when the new fuel pump was introduced the fuel pump kits came with Oetikers for both the hose and the firesleeve. I buy Band-its by the box of 100, and that is what I use on firesleeve during installation. If the clamp for the firesleeve needs to be on top of the clamp for the hose I will use a Band-it for the hose, otherwise I use Oetikers.
