I did a fairly thorough websearch trying to find out as much as I could about these counterfeit pumps but most photos/comparisons are a few years old. I purchased this pump within the last year and I have to be honest, it’s a really good imposter!

So there you have it – I suspect the real reason my fuel system has been failing HP pumps is because I’ve been getting bad parts! Makes me feel a little better about my initial design but at this point I’m committed to revamping the system entirely and eliminating the Bosch 044 from my setup.
More on that in a future post!
