7A pump info.

 

AISIN 5 on front case

No divider inside the pump housing. “big” gear is 7.3mm thick x 73.9mm diam. Smallest volume of all the pumps!

Front case has straight edges in top right corner, where plastic cover seals.

Outlet port hole does not fully align with 4A block. Genuine gasket has a slot in it!
