# Water Pump for 1968 MGB
Vehicle & Part Overview
The 1968 MGB should be equipped with a Moulton rubber-impeller water pump. However, mid-production variations exist on MGB water pumps, and quality differences between suppliers are significant.
Sourcing Recommendations
For a late 1968 driver-standard rebuild where a quality reproduction is acceptable, source from a supplier specializing in MGB cooling system components. Quality reproduction pumps are available, but pattern parts of poor quality can cause overheating issues — which on a B-series engine creates serious problems.
Safety Note: Do not use low-quality pattern water pumps. Verify the impeller type (rubber or metal) on your specific pump before ordering, as this determines the correct replacement part.
# Clutch Master Cylinder for 1972 Triumph TR6
Vehicle & Part Overview
The clutch master cylinder is a hydraulic, safety-critical component. The 1972 TR6 typically uses a 3/4 inch bore Girling-type cylinder as standard for that model year.
Sourcing Recommendations
Quality reproduction is essential. Pattern parts have inconsistent bore tolerances and seal quality, leading to known failure modes including swelling or perishing seals.

Reconditioned original route: Consider asking Rimmer Bros about rebuild/exchange services before committing to new reproduction, as reconditioned originals preserve original bore and casting integrity.
Safety Warning: If the clutch master cylinder fails, you lose clutch engagement entirely. On a TR6 with its gearbox, this can leave you stuck in gear or unable to disengage drive at a critical moment. Do not use cheap pattern parts for this component.
# Fuel Pump for 1965 Austin Healey 3000
Vehicle & Part Overview
The 1965 Austin-Healey 3000 (BJ8 variant) typically runs an SU electric fuel pump rather than a mechanical pump. Fuel pumps are safety-critical — a failing diaphragm or bad seal means fuel leaking near a hot engine bay.
Sourcing Recommendations
Pattern fuel pumps are not acceptable. Quality reconditioned or correct reproduction units are essential.
- Burlen Fuel Systems — The genuine SU manufacturer, offering both reconditioned original pumps and correct reproductions: https://carspanner.com/go/burlen-fuel-systems
- Moss Motors — Alternative source for Austin-Healey fuel system parts: https://carspanner.com/go/moss-motors
Even concours-standard cars often run a reconditioned or reproduction fuel pump in service rather than risk an NOS unit, as fuel pumps eventually wear regardless of quality.
Safety Warning: Do not use low-quality pattern fuel pumps. A failing fuel pump creates fire risk in the engine bay. Confirm your specific pump variant (early or late 1965 BJ8) and obtain casting/type numbers before ordering.
