That plate (item 18) has two rubber grommets (item 20) on each end that engages into channels in the tank.

To remove you have to rotate the plate 90 degrees.

To do so, temporarily leave one (item 21)bolt loosely in place, remove the second.

Then use a long 3/8" extension on a ratchet inserted into one of the square holes in the plate and pivot it 90 deg around the bolt.

Once the plate is disengaged, you slide to tank forward to disengage from the the rear mount (item 12)

Okay so i figured i have to take the crossover valve off that goes from tank to tank number 15 in the picture to fit the 3/8th extension in where 14 is labeled because it allows more room from top of head to tank

Correct, you will need to disconnect one end of the crossover hose (15)

Just slide the clamp (16) to the middle of the hose and pull it off the hosebarb. (17)

Sorry should have mentioned that.

Its probably set on there pretty good so will likely need a pick or screw driver to work around the circumference to free it. Good time to replace it too. It’s just 1/4” fuel line you can get at any auto parts store.

Since your going to replace it anyway, just cut it in the middle. That way your not dicking around trying to get it off the connector.

Do i reuse the clips that were holding the fuel line on ? Its amazing how much has to come out to replace the ignition i guess they want you finding anything else that may be wrong on your way. The tank is blocking the torx bolts holding the ignition the plate is blocking the tank the line blocks the bolts
