@tomkuester posted:I removed all ID from the pump and can't find the receipt, so I don't know the make. Maybe you can tell from the photo I posted if it matches yours. I bought the 'vacuum switch' from Summit for $59.99 07/22. I don't appear to have a leak.
I think that the answer to your question is that the pump is one of those Chinese products, made with no i.d.'s or visible part numbers. That way they can be sold to multiple vendors that can put their own id lable and part numbers on them.
I have seen the same pump from different sellers. I think that they are all the same.
It probably is an industrial part sourced (idea stolen) from another application that just happens to work. That's just how the Chinese roll.
They are definitely not victims of the "not invented here syndrome". They will steal anything and you can't stop them.
The main source of "Weber's" now is China. They are quite good. They just reverse engineered them and make their own at like $250 each retail. Everything interchanges with the Italian carbs.
They probably make good reverse engineered "Alien " flying saucers to .I don't know where they get there element 135 from though?
