CompCams

Comp-Cams Precision Maxjets

These jets use a precision “hole” to meter the fuel more accurately, unlike production jets, which are mass produced. Also, instead of a slot, which can deform and alter the jet flow, the Maxjets use a socket head. Jet sizes are not the same as Holley. Please check with our sales dept.

Moroso Fuel Level Control Kit

External forces like hard acceleration or cornering can cause erratic fuel levels, aeration in the float bowls, starvation and loss of power. A spacer mounted between the jet plate and the bowl creates a larger fuel reservoir, eliminating starvation. Fuel slosh and aeration is cured by inserting a cellular foam, creating a fuel cell that prevents fuel sloshing away from the jets.
