Message The gas line from the car parts store at $1/ft is probably SAE 30R7 which is fine for carburaated cars, but not strong enough to absorb FI line pressures. the FI line has a 900 psi burst limit!

Plus the 5/16th hose is a slightly smaller OD than 8mm. I found the OEM clamps work much better on 8mm metric line.
