P.O hacked up my inner fenders need repair ideas

You might want to consider moving the fuel pressure regulator to another location off the firewall. Fuel system components are not allowed on the firewall per most racing association rules. In the event of a crash, your regulator could be driven through the firewall, sending pressurized fuel into the cockpit. Find another location. Check out some other race cars for ideas. Just make sure those cars consistantly pass tech.
