Caution: Plastic and Ethanol
has anybody had any bad experiences with 10% ethanol Gas and plastic? i recently installed a rive primer kit and after being in use for 2 days the clear plastic T turned white and crumbled, separating the lines. luckily i discovered the fuel in the hull prior to starting it on the third day. if any body has any other incidents, i would like to hear what is going on out there and what can be prevented.
hope this helps somebody, i shoulda known better to use the plastic in the first place

Was the hose tee part of the primer kit, or did it come from somewhere else?

I see this all the time at work.
Fuel line is rated, but you never see the rating on the stuff sold for PWC. Buyer beware!
I "think" the current rating is "R7". This can be used with up to E85 IIRC.
"R8 is the same, except it can be used submerged in the fuel. "R7" can not be submerged. IE inside a gas tank for the electric fuel pump.
With "platsic" fittings, you are on your own.

Riva used to ship them with Brass now all they come with is the plastic tees, I never gave it a thought. the correct type of plastic would have never done this. Time to complain to Riva about this. I just made some adapters for a gas tank out of nylon 6/6 and it is impervious to fuel. I will send you a brass one I think I have a few, sorry for your trouble PM your address and please send me that pile of crap back so I can deal with Riva. I have two more kits sitting in the garage they will need new tees also.
