Keep the fuel tank on your pre-unit Triumph securely mounted and correctly isolated with this complete petrol tank mounting kit, designed specifically for 1947–1955 twin-cylinder models 5T, 6T, T100, and T110. This kit replicates the original factory arrangement, helping control vibration, protect paintwork, and prevent stress cracks in the tank and frame mounts.
Each kit typically includes the correct combination of mounting bolts, distance pieces/spacers, rubber isolators, and cupped/flat washers needed to mount the tank at the front and rear, depending on model and year. The hardware is matched in length and diameter to suit pre-unit frame brackets and tank lugs used on late-1940s and early-1950s Triumph twins. This makes it an ideal solution when rebuilding a bike from boxes, replacing missing or mismatched tank hardware, or upgrading tired original rubbers.
Manufactured to OEM-style dimensions for pre-unit Triumph twins, the components in this kit are intended to provide a snug, properly cushioned fit that keeps the tank stable without transmitting excessive vibration.

The Kit Composition:Â
- (2) x 82-0966 15/16″ long rear mounting bolts,
- (2) x 82-1808 1-1/4″ long front mounting bolts,
- (4) x 82-3814 Cupped Metal Washers,

- (2) x 82-5228 tall rubber pad.Â
The shouldered bolts have a thread pitch of 5/16-26 TPI (CEI).
The mounting bolts pass through the cupped washers and rubbers situated on the top and bottom of the petrol tank support brackets to effectively rubber-mount the tank. There are drillings in the heads of the front bolts for safety wiring the bolts, once installed.
The rubber pads are of varying lengths and are fitted between the petrol tank and the support brackets to achieve the correct height and clearance with the frame. The cupped washers form an abutment for the bolt heads. Consult the factory parts catalog for the correct orientation of the hardware.
