While doing my engine swap, I installed a new fuel pump, fuel tank, all
fuel hoses, filter, etc. Although the pump isn't noisy all the time, the
noise was audible right after I got the swap running. I don't recall
hearing it while the air cooled engine was still in but then the Jetta
engine is much quieter at idle. I guess its possible the pick up tube/plate
design of the tank is at fault. I don't know. I am curious why VW increased
the ID of that outlet at tank. Was it only because VW eventually deleted
the square pre pump filter from the design?
