Tell us what you need
Before you order pumps, hydraulics & fuel
A few things to check so the part fits the first time, or just tell us what you’ve got and the parts team will spec it with you.
- Spec the pump
- Give us voltage (12V), reservoir size, and single- vs double-acting. Dumps and hoists differ.
- Measure the cylinder
- Stroke, bore, and pin-to-pin retracted length are what make a cylinder fit.
- Size the fuel tank
- Tell us capacity in gallons, diesel vs gas, and whether you need a transfer pump and meter.
- Match hose & fittings
- Hydraulic hose is rated by ID and pressure; note your fitting size so the ends match.

Pumps, Hydraulics & Fuel FAQ
- What hydraulic pump does my dump trailer need?
- Most dump trailers run a 12V single-acting power-up / gravity-down pump — the motor raises the bed and gravity brings it home. Match the voltage, the action (single vs. double), and the reservoir size to what came off the trailer; the label on your old pump's motor or solenoid has most of it. Bring the plate or a photo of it and we can cross it.
- Why is my dump trailer slow or won't lift a full load?
- Check the cheap things first: low fluid in the reservoir, a weak or undercharged battery (12V pumps draw heavy current and slow noticeably as voltage drops), corroded battery connections, and a clogged reservoir breather. If those pass, suspect a worn pump section or a cylinder leaking internally. A load that lifts partway and drifts back down usually points at the lowering valve or cylinder seals.
- What fluid should I use in my dump trailer pump?
- Use what your pump manufacturer specifies — most call for a standard anti-wear hydraulic oil such as AW-32, with some recommending automatic transmission fluid, and cold climates favoring lighter viscosity. Don't mix types; if you don't know what's in it, drain and refill. Keep the reservoir at the fill line with the bed down, and change the fluid if it looks milky — that's water contamination.
