It was an exact replacement to the one that I removed. Easy to install. I am a happy camper.

Muy practico

Maneja buen concepto, solo que al manual le falta indicar, cómo realizar pequeños ajustes de regulación del gas


Had to make new bracket

Easy to install

Easy install used on toy hauler

Awesome so far.

It comes with compression fittings for your tank hoses, so no tape required on them. You will need to tape the outlet pipe fitting with gas Teflon tape. Took about 15 minutes to replace.
