I just replaced my in tank fuel pump. I tried finding a DIY for a MKV but only found a MKIV by dremhmrk2 from vwvortex .
I used some of his DIY to make this.
1. Pull fuse for low pressure fuel pump (in-tank fuel sender)
2. Remove bottom portion of back seat (Use NewaveRide DIY http://www.golfmkv.com/forums/showthread.php?p=902339)
3. Lift up passenger side carpet to expose access panel
4. Remove wiring module
5. Unplug harness from module
6. Start car and let engine run until it cuts out
7. Pry up wiring boot from access panel
8. Lift off access panel
9. Disconnect wiring harness from fuel pump
10. Using flat head screw driver, pry up slightly at these points on retaining ring
11. Use a rubber mallet and flat head to spin retaining ring counter-clockwise
12. Having rags handy, unclip the hoses (by pressing on the side of the D-clip) and pull off slowly (there will be built up pressure left in the pump, gas will come out)
13. Remove sending unit and gasket (be aware of the fuel level float attached to the pump)
When installing new fuel pump you have to pinch the points back down on retaining ring referred to on step 10 before spinning retaining ring clockwise to lock fuel pump in place.
Thanks for reading. Please post any other tips and tricks to this DIY.
Holy frack are the d-clips a bitch to remove! I'm stuck on this step atm. In fact, I'd probably suggest you reverse steps 11 and 12 since it's a lot harder to work precisely removing the fuel lines from the pump when the pump is wiggling all over the place.
Also probably a good idea to vacuum the top of the pump before you remove it since mine was covered in loose dirt that could get in the tank when the pump is being worked on.
Can anyone give me pointers as to how to remove those damned d-clips??
