raffaelli,
I was just looking at your pictures of your car, nice job by the way. My brother and I have a 90 Civic Si and we are doing some updates to it also. We have to add a fuel test port to our civic so I was looking at yours in the picture. Correct me if I am wrong, but if during a wreck if something came back and hit your fuel test port depressing it, wouldn't it spray fuel all over your hot engine causing a huge fire? Maybe that port works differently than I am thinking. It is convenent to get to but, I am not sure that is the safest installation. What if a person added a valve between the supply line and the test port?

Where did everyone else mount their test ports?
