Updated product: All details showed in the fifth picture. The parts of the OEM are the same as our previous one, so our updated one can solve the problem of OEM’s, too.

The black base was made of billet aluminum, we used the electrophoresis process to protect it from oxidation and corrosion, it's easy to clean. Also includes a heater plug.

The aluminum air bleeder screw which replaced the plastic OEM screw was more durable.

The hand fuel pump and two tubes were made of iron, oxidation surface treatment can effectively prevent corrosion and easier to clean.
