O-ring size?

[petrolhead]

I have one last question (hopefully) before I get my old FD-12 up and running again.<br />I need to replace the O-rings in the fuel/air line connector, the old ones were badly perished and came out in little pieces, so I can't see what size they were!<br />I tried a couple of car accessory shops, a hardware store, and two local chandlers one of which is an OMC dealer, but none of them had anything suitable. These seem to be a special size, "fatter" than a regular O-ring, does anyone know what size they are meant to be? I need both internal and external diameters.

Hi Petrol<br /> The I.D.(inside dia.) is .197 the width is .137 these measurements are in inches. The OMC dealer should be able to order them for you, OMC part#301824.

Cheers alcan, as I suspected the ones I'd been offered weren't wide enough, typically only around 0.075".<br />That i.d. of 0.197" is rather larger than I expected, but I'm sure you're right!<br />I guessed the OMC dealer could order them, trouble is OMC parts have to be ordered from Belgium, and they charge around $4.50 to do that which is probably more than the cost of the rings! From experience delivery is slow too, I think I may just get them from a US supplier which will probably be quicker and cheaper too.
