Early Sprites came with a mechanical fuel pump mounted to the engine. While perfectly adequate for the car’s original 948cc engine, would that setup be equally adequate for our Sprite’s supercharged 1275?
Concerned that the fuel flow would not be consistent enough at higher l…
The 1275 engine does not have a provision for a mechanical fuel pump in any case. The raised boss where the 948 mechanical pump went is solid and blank. There are lower pressure Facet fuel pumps that would have worked perfectly well without the fuel pressure regulator. As an owner of at least seven Bugeyes over a a 52 year period I have had 948 engines with superchargers, 1275 pumped up to over 100 HP, etc. I have never needed a fuel pump with over 2-3 psi.
