how do you replace a 92 sc400 fuel pump?
A little back story I tried jumping the fuel pump ecu by going from Fp to +B and I still get the stumbling, jerking under heavy accelerating. I found out that I didnt have the spark plugs torqued down all the way and that took some of it away, its not as violent when getting on the gas. Also I'm about 4 pounds low on my fuel pressure. My line if thought was that the fuel pump ecu wasnt going over from 9v to 12v under load.
So long story short I want to try to replace the fuel pump? How do I do it? Also who makes a drop in replacement, I thought I read somewhere maybe on one of the Aussie sites that Bosch(?) needed some wiring mods to work right?
Is the Python or Walbro fuel pump a direct drop in or do you need to fab it up?
And I thought this was weird, I notice a slight beeping as I'm starting it up, it almost sounds like its coming from the rear of the car.
