I decided to buy a NOS AC 4149 and a rebuild kit from Then and Now to replace the foreign made 4149 currently on the truck. It took a while to get the rebuild kit due to their staffing issues but finally got it. I decided to just replace the diaphragm and pulsator and leave the valves alone and give it a shot. Working better and seems to pump a more consistent stream of fuel, no hesitation at all. Only put a few miles on it so we will see.
Some pictures attached. $3.00 was written pump box! I did not pay that LOL.
