Hi there. I own a 1978 Golf Mk 1, with a complete 2,9 Corrado engine conversion. I am having problems with my fuelpump. It is making weird high pitched sounds, when the engine is running idle. It sounds like it spins, but not when running the wheels, only when idle. The engine won´t pull quite as it has previously. It spits, and chokes when I floor it. What can be the problem ? Is a new pump required ? I recently swapped a fueltube on the pump, since it was riddled with holes, but could I have damaged the pump somehow ? Hope to hear some good insights ;.)
