Well I managed to get the afr down to about 13.5 at idle, and cruising around town it was 11 to 11.5. Then I pulled into a parking lot and the afr was like 10 and I was saying "sweet perfect" then some Prius driver honked at me and flagged me down. I parked. He said "hey you're leaking stuff all over the road."
Shiiiiiiiiiiiiiiiiiii
Well sorry to the environment - had a nice trail of gas all over the parking lot to a nice pool where I took a couple seconds to shut it off. I looked under the car and sure enough - exact same spot - about 6" ahead of the fuel pump where the rubber meets the hard line to the front, it split again. I'm trying to figure out why this is happening. I'd assume extra pressure is diverted down the return line and shot back to the tank and dumped in. So I'm thinking pressure buildup is not likely - but i don't know. I think the metal line is somehow repeatedly cutting the rubber line... but the split is always perfect, and just in the outer layer of fuel line. The inner layer looks untouched...
