Findings from a trusted source differ to that in that link posted above.
I've got a 975 mounted internally in my car.
Begin Cut and Paste
The big daddy Bosch Motorsport pump is part numbered 0 580 254 044, it can flow
330L/hr @ 73.5psi and price is $550.95
The last 3 digits will be different for other Bosch pumps.
975 is a 228L/hr flow @ 73.5PSI at $340.95.
984 is the same as 975 just that the fittings are slightly smaller.
040 is 235L/hr flow @ 73.5psi and it comes with a screen for in tank operation and is priced at $359.95.
910 is 200L/hr flow @ 73.5psi at $229.95.
I know that although the 975 doesn't say its a in tank pump, it can be mounted
internal or external to the tank, maybe all the other Bosch pumps can be
mounted internal or external also.
