How to check fit and install a Boyd Welding aluminum or stainless steel transfer tank.
Measure Before You Order
Fit depends on your truck, bed, and cover, so measure your own setup first.
- Check that the mounting footprint, not just the tank body, fits your bed space.
- Check that the overall height, including the fill cap, clears your bed cover, latches, or cover housing.
- Allow room for mounting materials, cover rails, supports, and in-bed hitch hardware.
- Allow room for the pump and its connections in the position you choose.

Choosing a Pump Position
Pick the side you'll fuel from most often, and check the drawing for that position before you order.
| Tank | Positions | Fill Center from Back of Tank |
|---|---|---|
| 35 gal | Driver (DP), Passenger (PP) | DP 2", PP 10" |
| 60 gal | Driver (DP), Center (CP), Passenger (PP) | Not listed |
| 75 gal | Driver (DP), Center (CP), Passenger (PP) | 10.5" on all three |
| 100 gal | Driver (DP), Center (CP), Passenger (PP) | 10.5" on all three |
| 70 and 100 gal Service Body | Driver or Passenger, pump facing rear (DPR, PPR) | DPR 10.5", PPR 21.5" |
| 35, 60, and 75 gal Stainless | Driver (DP) only | Not listed |
Roll Top Covers
The 50 gallon roll top tank has an 8" × 11" step that clears the cover housing at the front of the bed. Check its 19" height against your cover's housing and latches, and use the published drawing to check your truck.
Known fit issues (not a complete list):
- 2025 Ram 2500 with a Roll-N-Lock cover: the latch and tank cap interfere on height.
- 2026 Ford F-250 with a Retrax cover: the cover fits, but the tank mounts interfere with the OEM in-bed hitch puck system.
Service Bodies
The 70 and 100 gallon service body tanks have recessed mounting with no external tabs, so nothing sticks out past the tank body. They fit between service body compartments with at least 48" of space. Measure the space between compartments and the clearance above the bed.
