Hi, It's the '85 Golf (gas, auto) again. Seems every fix solves the stalling problem for a few weeks, then the stalling re-appears. Last fix was replacing the 21 year old ignition switch 2 weeks ago and the car ran fine. Then yesterday engine would run fine for a few seconds then cut out. If wife tries to start engine while I have my hand on the main fuel pump, seems the main pump isn't running. After thumping the main pump with my hand, I could feel the pump run and the engine started. So I'm about to change the main pump (it's 7 years old, with about 40,000 km on it). I've never done this job before.
Question, Bentley says to pinch off the fuel line from the transfer pump. I'm reluctant to do this as the hose is 1985 original and is likely to crack. How much fuel am I going to lose? Will I just lose what is in the hose between the transfer pump and the reservoir? Or will I end up siphoning gas out of the (now full) gas tank if I don't pinch or block the line?
Thanks. About to raise the car on jackstands and investigate the job.
