1996 K1500, Vortec 350 So I'm replacing the fuel pump in my girlfriend's truck, and I got to the point of pulling the sending unit/fuel pump from the tank. How am I supposed to get this thing throught the hole? The screen on the bottom can't make it through. I don't want to screw up the sending unit because it's close to $300 to replace it. I think I know what to do to get it out, but I'll let someone tell me for sure. And also, the new pump is a "turbine" pump and it says it doesn't use pulsators and to throw them away. What's a pulsator? .
