I used 15.3mm stainless steel single ear oetiker clamps and a ratcheting clamp tool. They seem pretty stout. The fuel line is 14mm OD. These clamps are 15.3mm open and 12.8mm closed. The clamp tool is also used to cut the clamps off.

I added an ethanol sensor and replaced the whole low pressure side of the fuel line that runs across the top of the intake manifold to keep the factory one intact. But not thinking much of it I just grabbed some $3/ft fuel line from Autozone (ArmorMark SAE J30R7) and apparently it was only rated...
Does this fuel line look funny? It was a lot smoother looking when I installed it a few days ago.
edit: I’m an idiot. Off to Oreillys for some Barricade SAE J30R14 type 2
I may just try a straight E85 tune first I think. If it’s too inconvenient range-wise I will just wire it back over to the ECU for when the EQT flex files drop.
I definitely dropped the 15A fuel pump fuse in the engine bay somewhere between the battery and the ECU. Have to wait until the wife...
Finally got the ethanol sensor installed that I bought like 6 months ago. That fuel line on the left was a real pain. Struggled for 20 min before I hit it with a hair dryer and it slid right off. Now to get it wired up to the P3 gauge.
