I've been battling this problem myself since seeing air bubbles in the fuel lines. I changed one old line out, and other lines have been changed in the past. I'm interested in buying all the O rings for the system, since my lines all look good now. None are old and yellowed. I have several sets of O rings in kit, both metric and ASE, none of the kits contain the proper O rings.
I think that I saw someone post a memer who sells them, but can not find it now. I saw some link to a seller who had them for $55. but that is nuts for like a dozen O rings. Europarts sells the complete lines (each) for about $7-8 a peice. Thats where I bought the one I knew I needed.

Please post

Go to fryerpower.com He belongs to another forum I frequent and has put together a kit of viton orings for the 606.962. The kit includes orings for all the fuel lines, prefilter, shut off valve, delivery valve orings and tank strainer.

The dealer lines runs ~$65 for the set. OEM is buna rubber which is a bit softer and more susceptible to deterioation from changes in aromatics used when fuel formulas are changed.

McMaster-Carr sells o-rings made of all popular rubber/synthetic materials in a wide range of diameters and thicknesses. If the above does work for you, you might try www.mcmaster.com. Fast delivery, low shipping costs.

McM = 10 pkg minimum.

IIRC the above represents 6 different sizes.

I can give you all the different sizes if you want to go that route. You'll have lot of extras.
