This is a complete overhaul kit for the Fispa Fuel Pressure Regulator.
Please note that Fispa has produced at least two different versions over the years:
- The version WITHOUT a pin on the center of the diaphragm
- This version here WITH a pin on the center of the diaphragm
The difference between the two will be clear from this picture:
There are more differences than just the pin but the pin is the best indicator for which kit you need.
Officially, this set suits both the Fispa FB43 and FRB11 fuel filters with build-in pressure regulator.
The bolt pattern is as follows: circa 33 mm heart-to-heart and about 42 mm across (diagonally).
This set is E10- and bio-fuel resistant.
