the fuel pump on the vr4 went bad, and the sending unit looks pretty bad as well when took the cover off the car. so, I decided to change the whole unit if possible, along with the new fuel pump. initially, I thought about the RTM fuel unit setup, but too much. then I went on to look for a cheap replacement fuel pump for now before I figure what to do with the cover. then I found this fuel sending unit w/ fuel pump came off a 1991 Eclipse turbo AWD. I was excited cuz the unit looks identical, and I was hoping for a direct drop in to get my car running. don't laugh, I am a newbie to vr4. I didn't know the 1g DSM tank is deeper than that of vr4. so, I found out the eclipse unit is about 1 1/4 inch longer than the vr4 one. after few thoughts, and talked to my friend, I decided to modify the eclipse fuel sending unit to make it work on vr4 since the cover, and wiring on it are so much better than the original one on vr4. here are the steps what I did:
1)take out the fuel pump(I left the wiring on the pump cuz they are still good) off the eclipse
2)make a mark about 1 1/4 inch from the bottom of the unit, and cut it off
3)cut the fuel line cup that connects to the fuel pump. you want to leave an inch of the tub for connection to the fuel pump
4)clean the cut area to make it smooth. then get a section of a rubber fuel line hose to connect the fuel line tub to the pump
5)secured the pump to the sending unit with 3 hose clams.
bingo, it is done, as you see in the picture. everything else on the eclipse unit is the same as vr4, except the length of the unit. oh, also, the orientation of the unit is little different from vr4, but that is not a problem at all. you just need to turn the unit to line up, and put bolts on.
I installed it on the car today, and started the car right up. I felt so good when I heard the car running again.
