Re: Universal 5411 diesel RPM issues
I'd change your fuel filters first; cheapest and easiest thing to do. Check the fuel/water separator filter for water; you might have some water in the tank.
Then I'd put some more fuel in the tank (fill half way or more) to dilute that old fuel, but draining the tank first would be a better solution if at all possible. At least you don't have a 170 gallon tank.
Star Tron products have been a god send for us with a 30 year old tank. Use a fuel treatment product.
Check that the tank vent is not blocked.
