I was having issues with the engine starting and my research said to check the anti-syphon valve. It is aluminum and appears original. After getting the fuel line off, I used a cresent wrench on it while holding the square top. The anti-syphon valve broke off. Ran to west marine and grabbed one.
My problem is that i cannot get the little part that sheered off out of the square box of the unit.

I loosened the nut under the square box which goes into the tank but the entire assembly will not move. I am afraid to put too much twisting on the square box for fear or breaking the top of the tank.
Pardon the terminology if wrong. I attached pictures.
1. Does anyone have a link to a picture so I can see how the sending unit is attached to the tank? Maybe mine is just "stuck" but I do not want to twist too hard and ruin the tank or opening.
2 Does any one have the part numbers for the components or for the entire sending unit? (assuming I get it out).

Any other idea are welcomed, but at this point I have no way to put the anti syphon back on.
Thanks
