I personally would likely seal the area around the stripped bolt with a small amount of gas safe RTV on both sides of the gasket. Put it together and cross my fingers. This goes double if the bolt is giving even a small amount of clamping force.

Using a helicoil seems over kill for such a small bolt. Remember the torque is only supposed to be 10 Nm (89 lb-in).

An old timers option is wrap thin copper wire around the bolt to "take up" some of the space lost by the stripped threads. Likely for the size bolts used on the gas tank will need fairly thin copper wire. Perhaps remove the insulation from lamp cord and use the individual copper strands.
