I have driven for the past time with stall/stutter on WOT. After finding a lots of smaller leaks in the braided vacum hoses, and TIP, I finally tested the fuel pump iaw this tread:
Agu boost pressure and problems please read.
(My score on flow was about 200cm3/12,1volt, and 2,5bar with vacum and 3.0 without. Pressure after 10 min around 2bar.)
The flow should have been more like 400cm3(0.4 Litre).....
So I gess my pump is bad and need replacement. My car is a stage 1 chip (If I am to trust the previous owner...).
On ebay there is one pump assy for sale(the whole unit):
FUEL PUMP ELECTRIC AUDI A3 8L 1.6+1.8 1996 ONWARDS | eBay
Or possibly oppgrade (single pump):
BOSCH fuel pump SEAT,SKODA,VW 0986580824 | eBay
Not sure if the latter will fit my car doe
Is it possible to replace just the pump in these sender units?
Question two: what about the fuel lines, those hard plastic ones. They have now 14 years on their back, should I replace them?, and if so, with stock parts, or other?
Thanks for any suggestions or recommendations?
