What is the change interval for a fuel filter and what are the steps for changing one...i have about 30k on mine.

 

I think the change interval is every 30K, I usually do mine sooner than that considering a fuel filter is only like ten bucks. Replacement is very easy, the fitting in the front, I use a combo of a cresent and flare nut wrench to break free the nut. On the rear, just squeeze the plastic prongs and wiggle the filter out. Have rags and a drain pan handy to catch any gas that has spilled.

 

would this cause hesistation and missing up top?

thats the dyno before my cap and rotor install but its doing about the same.

 

There is no change interval on the fuel filter that I am aware of.
