The girls have to figure out why an '87 C10 isn't running anymore; they know it's a fuel problem that happened after an EFI setup was installed; they finish up with a new disc-brake kit; Bogi takes a field trip to show how custom fuel lines are made.

The girls take an old AMC Spirit drag car and get it ready for the street by changing out the oversized carb. They bring in a special guest to help them pick out the right carb and tune it on the car.
