Diesel Tank Fueling

Are you in an emergency situation where your vehicle needs fueling? Don't worry. We are at your service 24/7, 365 days a year. We have on-site skid tanks with high flow pumps that will help make fueling easy. We have few diesel fueling options for you:
  • We can supply your company a double-walled skid tank and pump as long as fuel is bought from us. These tanks range from 500-6000 in size. If inside, the only cost to you would be the hard wiring to pipe the fill and vent. 
  • You can lease a diesel tank for the duration of your job or through the months of your busy season.
  • You can buy a tank from us. We have tanks ranging from single-walled 330 for inside your building to a 20,000-gallon double walled tank with a fueling station and canopy designed to suit your fleet's needs.

"We had an underground 1000 gallon oil tank removed by Superior. They were awesome. They installed a new state of the art oil tank. When they finished the removal they left my yard picture perfect. I highly recommend this company. Their rates are the best around."
