Water Pump Large Impeller No Bypass
These pumps have the same aluminum housing and the same deep impeller as the standard GWP134 pump, the only difference is that the bypass adapter has not been drilled. This means that if you are running without a bypass hose you don't need to plug it, therefore one less possible leak. This pump moves the same amount of coolant then as the GWP134 pump. These water pumps have the much larger impeller, it sticks into the block very slightly more than 1/2"(14.03mm). This water pump will fit all 1275cc blocks and all small bore blocks 948-1098.
- Austin Mini 1981 to 1996
- May be retro fitted to all A-Series Engines for deleting water bypass.
