Jet feed, pressure feed difference

[Ivor Hawkins]

Jet feed is the standard “spit and hope” set up found on the vast majority of Austin Sevens and works surprisingly well, pressure fed is found on some sports models and most modern racers and is identifiable by the external oil feed usually going into the nose piece.

If your car is just a standard road car the jet feed (splash fed) I’ll be fine, if you are building a special or a racer you’ll need the pressure feed and all the other parts to go with it!
