> L-Jet fuel pump relay, why did they bother?
L-jet only! why didn't they delete the fuel pump relay?
D-jet guys, don't vote, this poll is for L-jet only! Relay #75 on the relay board is labeled as being for the fuel pump. And it will in fact run the fuel pump if you turn the relay on, but the fuel pump is meant to be run by the double relay under the batter. In fact an L-jet car runs fine with relay #75 removed from the relay board! This raises the question, "why would they have kept putting relay #75 in L-jet cars?
Porsche did delete it. If you have one in your relay board then the PO must have put it there [ 3 ] ** [30.00%]
It cost more to drop it than to just keep putting it in. Besides, it serves as a handy spare [ 4 ] ** [40.00%]
Intentionally left in to allow a means of manual over ride of fuel pump (just ground T4-III) [ 2 ] ** [20.00%]
Other (please explain) [ 1 ] ** [10.00%]

After spending many hours wrestling with a fuel pump issue, and wasting a lot of time on relay #75 on the relay board. and ultimately discovering that relay doesn't run the fuel pump on an L-jet car, I have to ask... why the heck is it even there if it isn't used?
