fuel leak... please help

Lately when starting vehicle I smell gas, so I opened the hood and discovered where exhaust manifold meets the engine, right underneath the manifold gas is dripping. Any idea as to the fix for this problem? Please help I'm new to RX7's.

Thanks,

Be careful your car may catch on fire!!

Most likelly it's the fuel pulsation dampner, needs to be replaced immediatelly or you'll regret it.

dig in and look hard with a light while the motor is running and search for it thats how i found my leak it was spirtin out in small sprays!!! try and get under it somehow and look around also if you cant find it from the engine compartment they do sometimes catch fire...

might just be in a line or somthing easy

Pressureize the fuel system by jumping the yellow test connector under the airbox and then set the key to IGN. The fuel pump will run and you can find the leak easily. In that area, it could very well be the pulsation damper. If so, then replae it and while you are there replace the rubber fuel lines as well. Use the proper fuel injection hose and fuel injection clamps (not worm gear clamps).

probably not a good idea to run the car if its leaking gas unless you have a fire extinguisher. lol
