These fit B, 2B, 3B with the inline injection pump. Also, the 2H diesel with the 5 speed transmission.
The 2H with automatic trans uses a different injection pump that does not use the leather diaphragm. 12HT does not use a diaphragm.
The rotary injection pump equipped models do not use a diaphragm.
Diagnostic tips: Signs and symptoms that your diaphragm is failing or has failed: high idle, low power, considerable blue smoke especially on deceleration or going down long hills using compression braking.
You can further diagnose this very simply by removing one of the two clear hoses - with the engine shut off - from the 'throttle body' of the engine that runs to the injection pump and then applying vacuum (or if you're more daring - sucking on the end of the hose), if it will not hold vacuum and air flows freely through, it means the diaphragm is in need of replacement.
