With this fuel funnel you get the best of both worlds. Funnel has a 1.50" filler neck with a press in fine micron fuel filter that can be replaced in the event of it becoming lost or torn. Funnel is 8.50" diameter and close to 10.00" deep.
Some more great benefits of the funnel is it is made from spun alum. so clean up is an easy task and it won't be affected by solvent or brake clean. The hair net filter that goes on plastic funnels doesn't allow the racer to set the funnel back over the top of the fuel jug easily and sliding the plastic funnel into the tank can shave plastic off the funnel possibly leading to plugged nozzle jets and we all know what happens next.
Don't fall victim and enjoy your day at the races.
