It's 22mm where the petcock attaches if I recall correctly. Has anyone found a female attachment of that size with the barbed nipple on it? I'd like to do away with the petcock completely and just started looking, but if someone has already ventured in that direction it would save me some time. I have the electric shut off already, plus a fuel gauge to go with the I/S tank, and since old habits are hard to break....I still reset the odometer with each fillup. If I can find something that serves the purpose, I'll install a quick disconnect just below it and in line with my external filter. I'm just in the "thinking" stage for now, but would like to have it done for summer.
Any suggestions?
Try this, I emailed and they said it comes in 22 mm. It's the low profile barbed fitting # 76-6312-B part way down the page. This is the one I'm getting for my Petcock free setup.

I'll have to see how that internal screen compares to the OEM filter, I might be able to do away with my external filter if this one is fine enough. Sure would make more room for the quick disconnect. Thanks again, I kept their site in my favorites listing for "fuel systems."
