Apparently there is a lot of defective aftermarket fuel pumps lately. This year the Oregon 07-700 pumps all fail except one in minutes of installation and operation. And I had a group of five on back order from since April and told Friday the latest batch they received failed the testing so they were still list as back order. I just cancelled that part of my order.
These are simple pump and no one can make a good one any more that can handle E10 fuels? I did read earlier this year that the EPA approved the E15 use in the US so it could be sneaking in here. But customer that I had three pumps to fail on was using supposedly 100% pure gasoline.
On the Oregon pumps I was able to disassemble them and found the rubber fabric check valves were curling up from fuel contact damage.

Anybody have these issues or is it just me?
