Mobile fueling or bulk delivery: which fits your Connecticut site?

Three delivery formats. We’ll quote whichever fits your volume, site access and cost target.

Wet-Hose Fueling
Mobile fleet fueling
Overnight or day shift, fuel direct to each tank
A driver pulls into your yard after hours, fuels every truck or piece of equipment directly, logs each fill, and clears out before your crews arrive. No staff required on site.
Best for: Trucking fleets, delivery yards, rental fleets and service vehicles.
Tank Wagon Delivery
On-site tank fills
20 – 4,400 gallons per drop · same-day or scheduled
A smaller delivery truck fills your day tank, jobsite bulk tank or generator. The flexible option when volume varies or site access is tight.
Best for: Construction sites, generator refills, day tanks and smaller bulk storage.
Transport Load
Bulk transport delivery
Full transport loads to 7,500+ gallons · scheduled
Tractor-trailer delivery straight into large bulk storage. The lowest cost per gallon for high-volume buyers.
Best for: Data centers, large industrial sites, agriculture and rail yards.

What diesel tax costs per gallon across Connecticut

Connecticut's combined on-road diesel tax is among the highest in the country: every gallon of clear diesel carries $0.7473 in federal and state tax before sales or local taxes.

Connecticut is one of the few states that taxes dyed diesel heavily ($0.4973 per gallon), so switching off-road equipment to dyed saves less here: about $0.2500 per gallon. Rates include federal and state per-gallon taxes and fees as of October 5, 2026; sales and local taxes are extra. Not tax advice. See every state's breakdown →
