I used the correct gas cap. Read the service manual re: pressure in the
fuel tanks and vented vs semi vented caps.

Side topic to the other threads going about vapor lock feedback. I've read
here before about positive results on coating the fuel tanks with a heat
reflective material, to help the tanks from absorbing road/engine heat. I
believe that we have experienced fuel boil in the tanks last year in 93+
degree temps on the Interstate highways. On the hottest days, the gas cap
was making a noise and upon opening the cap, fuel actually gushed out.
I figured it certainly can't hurt anything by doing this and I can see a
number of benefits. To me, having the tanks under that much pressure sounds
dangerous. Has anybody had positive results and what did you use?
Thanks as always.
