Okay DSM experts, I need a little help from you guys. I got this aftermaket Walbro Fuel Pump for my 2.0L 420A FWD 98' Eclipse and im having trouble trying to replace the old one. I've removed the back seat and took off the metal plate where the fuel pump is supposed to be and unpluged the harness that was plugged into it and when I lifted off the plate, I could see the gas and the gas tank. There is an old, rusted color, brownish looking fuel pump hanging from the bottom of the plate. Im guessing this is what needs to be replaced with my new Walbro fuel pump, the only thing is... how do I do it? The plug or harness isn't compatible with the Walbro one and im just confused as to what to do. Can anyone please help me??? Perhaps maybe there are a few more components or parts I am missing or need to buy for the installation but I really dont know. The instruction manual is so confusing to follow, I feel like I need some advice from you experts. Thanx. Feel free to PM me.
