During warm weather operations we have been witnessing an intermittent bog after a short shut down. When this occurs you hear a very distinct audible hiss from inside the tank. I pulled a pump assembly yesterday and noticed missing oeitiker clamps. I'm wondering if the warm fuel is expanding the fuel line and letting the fuel bypass the FPR. I will install the missing clamps and report back if this is the cause.

You sure there is supposed to be a clamp there. Typically oetiker clamps are not used on thin tubing over barbs like that. Is the side with the clamp the pressure side and the barbed side the return that isn't under pressure?

Pressure side is missing the clamps. The PII diagram has a clamp on the pressure side of the valve. The tubing is a formed piece. We are still sorting this out. Not sure if this is the culprit or another component in the assembly.

Be interested on what you find out to, had this exact problem last week when I was in the mountains. It was above or at zero everyday to. Glad to know I wasn't going crazy when I was hearing that sound

Two days of riding and the problem has not surfaced again. Temps were much cooler this weekend though. Clamps??? Will keep thread updated if it surfaces again.

Is this a common problem? The pump on my 14 pro was whining after short shutdowns. Sled only has 200 miles on it, temps were 25-30 degrees.

When cold this morning i heard nothing. Also I wasn't experiencing a bog, just a whining pump after start up.

Is this the pressure side? All the pump assemblies on the 13-15's I have seen do not have clamps on this line.
