Wow Ricks put his prices up huh. That is a nice looking tank but the filler needs to be capped off and relocated for a CCX. It is also only 17 gal which aint much in a single digit MPG car. My stock replacement CCX tank is about 24, I think the Comp tank is in the low 30's but I'll have to redo the math on that. The last picture shows it does hang down a bit under the back. That looks original, makes a statement and shows it off a little but it could be raised some. The CSX cars use an inner fender in front of the extensions. I recommend the same in a CCX. I did have one tank leak around a fuel fitting. I made him a replacement tank, drove 12 hours to his house, put the replacement in for him and made him happy. The tanks are all air tested 3 times in 3 different positions with 4 psi. My tanks are built with baffles inside to stop sloshing and have a trap around the pickups to keep fuel at them.
This is looking at the fuel pickup with the top off the tank, it has a trap around it and a baffle beside it.
Brakes are another subject I'll post a link for you on.
