My new-to-me 89 GW was having trouble starting and gasping when taking off, so I changed the fuel pump. The old pump had a loose and wiggling arm, so felt confident that this was the main issue.
I read that I would be a good idea to put in an extra fuel filter just before the pump to prevent any debris from the tank fouling the new pump. I also changed the main filter between the pump and carb with the return line
Now, it takes a few tries to get the engine to start (a drop of gas into the carb helps speed this up), and it doesn’t seem to take off as fast when I gun it.
I was wondering if the additional filter is creating too much resistance for the fuel to get to the carb when starting the engine and too little flow to allow a quick take off?
