Messing with the car today I noticed where i'm missing a cap on my schrader valve it is leaking fuel , first of all is this normal and second , Where can I find a replacement cap? thanks

 

The cap is only there to keep dust out. If the Schrader valve is leaking, either the valve core is loose or damaged. You have to tighten the core or replace it. Do NOT rely on the cap to keep it from leaking.

Be careful when working around the Schrader valve. It is only swaged onto the hard line, and will break off very easilly.
