About Fill-Rite
Fill-Rite has been building fuel transfer equipment in Fort Wayne, Indiana since 1957. Now a Tuthill brand, it earned its reputation the hard way, by making cast-iron rotary-vane pumps that stand up to continuous, real-world duty on fleets, farms, construction sites, and equipment yards across the country.
Today Fill-Rite makes a complete fuel-handling lineup, from 12-volt and 24-volt DC pumps to 115-volt and 230-volt AC pumps, hand pumps, flow meters, nozzles, hoses, and filtration. Whatever you are moving and however you power it, the parts are engineered to work together as a system.
That focus is why Fill-Rite is the name so many operators specify by default: durable where it counts, simple to service, and backed by a Limited Warranty. When fueling your own equipment is part of the job, it is the brand you buy once.

Extreme Dependability
Ordered this pump to replace an existing pump (Same Brand, Same Model) that has been in service for the last 12-13 years being used on a daily basis to fuel plant loaders and genset. This pump is pumping a minimum of 150gals every time it comes off the hook. We have been very pleased with the dependability of Fill-Rite pumps. When this pump is down it is costing us production.
