Aem rebuild kit …. Quick and easy change if you know what you are doing.
Fpr was sitting for awhile in a box…. So thought diaphragm was maybe going bad …. Bought rebuild kit and, it has a updated return port plug that has a bigger opening…. Thus opening the return line flow a bit more …. Definitely better response compared to older one that was in my Fpr. Happy fueling!!

Inaccurate Description, Missing parts
Inaccurate description and missing parts. The description states this item includes 3 orifices (also shown in picture) but only comes with one. In certain parts of the item details it says only 1 orifice is included. The orifice included is the largest one (.250 size). Please clarify this for other buyers. Also my package was missing the O-ring.

The fit is good. The replacement part works better than the original.
