South Korea made pumps (Daewha Fuel Pump Industries):
I have categorized them under the supplier who the vendor says they get it from. The GMB tech support rep told me that carter, spectra, and them all have their pumps manufactured at the same factory in south korea. This chart just shows the flow of re-branding going on here.
All of these pumps are manufactured by Daewha the 3 companies that buy direct is Carter, Spectra, and GMB. These companies then sell to parts stores for their own brands as well. All are identical pumps.
Carter Fuel Systems:
- Carter
- Oreilly's Precision Brand
- Napa
Spectra Industries:
- Spectra Premium
- Carquest
- Delphi
- GMB
Carquest claims that their pumps are the "only mechanical pump made in the USA" however when you call them their rep says that they source the pump at least for our fsj's from Spectra which gets their pumps made in korea.
China made pumps
Surprisingly there only seems to be one company getting the pumps made in china
- Crown
- Airtex
- Bj's Offroad
- Team Grand Wagoneer
There also is the Mopar pump you can get through Chrysler vintage parts for $100 but thats probably a crown pump as most parts were in the later days.
So there you have it. Not many real options available.
