US Made
OE Fitment
Delayer Spring

SPECS:

TECHNICAL:

Apply a small dab of lithium white grease to the cup before installing. Polish the well with crocus cloth, or 2000+ grit sandpaper to provide a smooth glide. Today's gas has very little lubricant.

Note: Even the best cups will fail if the ethanol is in high enough concentration. Using Ethanol Defense will be helpful.
Carefully insert the pump being careful not to fold the rubber cup.
APPLICATIONS:
We cannot guarantee fitment unless you match the carb number on the tag with the list below.
