That is a completely different pump Hervey was selling. it is from a 2003-2007 flexfuel gm truck. The pump is larger capacity due to flexfuel. Its not a great fit for the car. Furthermore he provided no QC fittings so people were clamping hoses onto an unbarbed fitting.

My pump is the Bosch 67317. I got that one because the owner that convinced me to design the fuel gauge ECU also used that one. I don't know if Hervey used the same. I did do a max pressure test and it pegged my 100 PSI gauge. I also did a flow check at 75 PSI and yes it is way more then any owner would need.

The internal should suffice, but, these pumps were not made to hold pressure back when the car was off like in the Delorean fuel system which is why i think some of the other pump models failed after a while. For an $18 check valve, I just bought one and installed it "just in case" since I was making all new fuel lines anyway.
