way too easy !!!!! I did mine as follows. Crush the chrome pipe as close to the head as possible with a pair of heavy duty pliers then with a pair of heavy duty side cutters cut the flat section that you just crushed and then a deep socket will remove the injector. no need to loosen or remove the seat or tank. did mine in about 30 minutes.
Buuuuuuuuuuuuuuuuuuuurrrrrrrrrrrrrrrrppppppppp !!!
