Lingering fuel smell in oil

Put a fuel filter on with a return off of a 1987 dodge truck . last year before injection. And the first years of this ethanol fuel. The fuel dead ending at the carb will pressurize when shut down. A return can be added with a 70 back fill tube with vent tube . Or installed in the top front of the tank

You can use Wix (or equiv) 33040 --5/16-- or 33041 --3/8-- filters as well.
