Damn.
Why is it the o-ring kits never have the o-ring i need? Thought i would be smart and buy the sae and metric kits. Neither kit has. The fuel filter was missing one,a holes tightened it til it stopped leaking. Try getting that bastard apart. Got it but it was no fun. Rarely is. Unless i replaced it before.
We have hundreds of different o-rings at work and I still can't always find the correct size. I think some manufacturers have custome sizes made so you have to buy their kit. And its usually really small ones that are near impossible to make.
