737 Center Tank Fuel Pumps

Postby BoeingMn » 04 Oct 2020, 10:53

Can anybody confirm this:

On 73CL there is no fuel pumps installed inside the center tank
On 73NG there is

If this is true, any logic behind doing so?

Highly appreciating your pro feedbacks

The Cl centertank is really between the wingroots. The NG centertank extends to halfway between the wingroot and the pylon.

The pumps are located on other places as well, due to design issues i guess. The wing is completely different, also inside. So they installed a pump on each side on the leading edge area under the kreuger flaps and 2 on the bulkhead in the wheelbay. The CL pumps where installed inside the wing lower skin inboard of the pylon into a cannister.
