Fuel Tank Service – Don’t Get “Kreemed!”

When you go to the time, effort and expense to rebuild your carbs, they will have absolutely pristine innards. It would be a crime to connect them to a contaminated fuel tank. Now’s the time to evaluate the condition of your fuel tank. At a minimum, drain or siphon all the old fuel out. The drain plug is located near the rear master cylinder.
