Mechanical fuel pump
Years ago I had a Carter M6902 that I had in a box, my from my old 83' Ram W150. I was going to rebuild it when I got the chance. Until she threw the box away during our move.
I was a bit pissed. It was made in the USA at the time
I then bought the M6270, I then just put on a regulator and set it to 6 psi. I've been using it since early 2017. And I daily drive my duster alot, it has never let me down, going strong for well over 30,000 miles. Unfortunately it said: "Made in Mexico." Still better than China.
From what I heard about the new Carter fuel pumps... They're now pretty much all made in China.
