Ok, so I'm sitting at work and have time to kill but my 510 is at home and I want to replace a couple hoses. I had a leak from under the intake manifold so I took off the manifold and can't locate the culprit but I want to change out the 3 hoses to see if it fixes it and if not at least I wont need to do it when one does fail sooner or later. 1 is shaped like a question mark which I already found a replacement for at Pep Boys. The others are straight hoses but I don't the ID on those 2. Anybody able to chime in? It would be greatly appreciated. The motor is a s13 redtop.
