Air-O Filler Plug Gasket

[holliswood]

I recently ordered and received my Buna gaskets from OCP and was wondering if I’m supposed to leave the old lead in the plug and just slide the gasket over the lead?

If that is the case, I’d only hand tighten the filler plug? I tried searching through the forum and couldn’t find anything. It seems like I remember seeing several posts on this topic before the switchover . No complaints from me on the switchover. I’m either not searching the site correctly or any previous information on this subject got lost.

I'm not familiar with OCPs gaskets for the 327 style filler caps. But I personally have always left the lead gasket and used a fuel resistant o-ring on top of it. That way you can tighten the filler by hand and if wanted it could be removed to be all original as well.

Thank you for the information Toby. I’ll leave the lead in the plug and will see how the Buna gasket performs versus the viton o-ring.

Steve, when you mention cleaned lead, I’m assuming you mean the lead being fully removed from the plug? I have two Air-O’s and can try what Toby mentioned and what you are suggesting if I am understanding you correctly.

NO , just cleaned off real good till nice n shiney with a little wool , then slap this right on top . this size gasket fits n stayes on the plug real good . i have put in new lead gaslets , replaced the lead with buna n ..... this is by far the bestest easiest way to go IMHO dont make more work than you really need to .

Good advice and thank you Steve

Use the 118 cap gasket. Iirc. Can put on finger tight like normal cap.

@SteveRetherford

I used the gasket you recommended and it’s performing nicely

@Tgarner01
I’m hoping to get to my other Air-O shortly. I believe I have the correct fuel resistant o-ring on hand.

I’ll look that one up as well. Thank you

Industry # 110 o-ring is the size you want.
