Part #B4363GS
This OEM replacement fuel gauge cap is designed for use in generators. It comes in a cylindrical shape and has a built-in window to easily view the fuel levels without pulling out the entire cap. It is approximately 5.25 inches in length, while the head has a diameter of 3 inches. The purpose of the cap is to cover and protect the fuel gauge, which indicates the levels of gas available in the tank. It prevents dirt and debris from entering the gauge area and prevents fuel from leaking out. A faulty cap will allow contaminants to enter the gauge, and cause fuel to leak, leading to inaccurate fuel readings and safety risks. Twist the cap to remove it and clean the surrounding area thoroughly. Place the new gauge cap in position and ensure that it is locked in place.

Breaker, Circuit, 20a
Part #209872GS
This circuit breaker is an important safety device found in the control box of your generator. It protects the electrical system from overloads and short circuits by automatically cutting off the electricity flow when it detects excessive current. It can handle a maximum current of 20 amps. You can tell if a circuit breaker is broken by checking for visible signs of damage, such as an unresponsive button, cracks, or burnt marks. If the circuit breaker repeatedly trips, the breaker may be faulty or overloaded. You will need a screwdriver, a set of pliers, a socket set, and a nutdriver to replace the breaker in your generator. Follow the instructions in your user manual to access the control box. You typically need to remove the carburetor and the fuel tank before removing the cover of the control box. Please note that this OEM replacement part is sold individually.

Assembly, Holder, Brush – Part Number: 66386GS

Assembly, Holder, Brush
Part #66386GS
The brush holder assembly in your generator keeps the brushes in place, allowing them to touch the rotor. It consists of a plastic brush holder and two carbon brushes with lead wires and attached springs. You can usually find the holder assembly inside the generator housing, near the rotor and stator assembly. If the holder assembly is broken, it can cause improper electrical contact between the brushes and the rotor, leading to a loss of electrical current transfer. Additionally, over time, the brushes will wear down from use, resulting in inconsistent contact with the rotor. Look for visible signs of damage like cracks, breaks, or deformations in the holder. A damaged holder can cause unstable voltage, power surges, or your generator failing to generate electricity altogether. To remove the existing brush holder assembly from your generator, refer to your user guide for detailed instructions. It may involve removing a cover or access panel to reach it. Use a nut driver or suitable tool to disconnect the assembly from the rear-bearing carrier and any connected wires. Remember to magnetize the brush assembly and conduct a generator test after installing the new one. Please keep in mind that this authentic OEM part is sold individually.

Dry rotted rubber

  • James from PICAYUNE, MS
  • Very Easy
  • Less than 15 mins
Put some dish soap on the rubber, push into the tank hole, slip 1x2 into the handle of the tank and over the new part and pry down pushing it into the hole. Took about 2 minutes.

old valve dripped gas when opened on cold sub zero day
4 of 7 people found this instruction helpful.
  • Alan from RADFORD, VA
  • A Bit Difficult
  • 1- 2 hours
  • Pliers, Screw drivers
old valve easily pulled out with screwdriver and pliers

install difficult due to 40 degree cold temp and bushing didn't want to squeeze into fuel tank hole

install required lots of liquid soap on bushing, which popped into place by using upward prying pressure from 3"X24" plywood braced into under-shelf of gas tank
