Fixed two problems with my Aux tank. It is a recycled aluminum tank from a boat. I noticed the cap (OMC type fuel cap) was rusted inside....NOT GOOD! I also noticed that fuel was sloshing out around the cap. Yep, the Diesel did not play well with the rubber seal either.
Time for a new cap. I got a 3" locking cap designed for "Diesel Only" and neck from Boyd's Welding in Ocalla FL and had it welded into the tank. Voila, no more problems.
