90hp, 2 different fuel pump part numbers?????

[fishertexas]

anyone know the reason behind these.. are the fuel pumps the same or are they really different?

16700-ZV5-003 - SUP; PUMP ASSY., FUEL (Honda Code 5020466).
16700-ZW1-004 - PRI; PUMP ASSY., FUEL (Honda Code 6816839).

any thoughts? The parts break out have them as the same number, but twice with 2 different part numbers

If I look up a BF90AW on the Honda parts lookup, I only come up with the 16700-zv5-003.

I think they may vary by serial number.

Replay with the frame serial number and I'll double check it.
