AED 5110 Holley .110' Viton Needle and Seats (pair)

We cover the complete spectrum of Needle and Seats for gasoline and alcohol carburetors. First we have the traditional .110" Viton hi-flow units designed for up to 650 HP on gas. For power levels over 650 HP with single carburetors or with marginal fuel systems we recommend our special .125" viton tipped assemblies which flow approximately 25% more fuel than the .110" and will accept up to 7-8 pounds of fuel pressure. For alcohol applications our special .150" stainless steel needle and seats are the ultimate in fuel capacity and seating ability where optimum fuel flow is required. These special hi-flow needle and seats will not accept the standard 7-8 psi at idle like conventional needle and seats. Reduced fuel pressure at idle is required to properly seat at idle. All assemblies come complete with our special reusable needle and seat gaskets.
