hello everybody,
after relentlessly searching the depths of the internet for help, i have finally found this thread where lots of you guys seem to know a while lot abkut these pumps.
right now, i have 2 cp4 pumps in my garage, so if needed, i might also post pics of the pumps while solving my problem.
following problem:
it seems my cars current fuel pump cannot keep up with the needed amount after some tuning...
car is a 2017 audi a6 bitdi. the fuel pump from the car is the cp2 r80 variant. i will add the bosch code tomorrow.
i have another almost new cp40hs2/L99/40 lying around here. that is the highest output cp4 i know of.
now, i wanna put that pump into my car. first obvious problem is that it is a left rotating pump whereas my car needs a right rotating pump.
second, i would want to use one of the plunger heads from my old pump since it has the right angle in contrast to the L99 one which goes in a different direction.
how can i achieve this? i will probably start opening up the pumps tomorrow.
i was thinking of taking parts from both pumps to create the pump i need somehow.
but first, i need to figure out if i can use the left pump or not, or how it differs from a right pump so i can start mixing parts until it is what i need it to be
