Definately have a leaking number 4 injector on top side steel fuel line. Im guessing new o-rings will solve this?
Also I was driving and switched to my back tank which I filled up the week before. Fuel guage registered quarter tank. That is a major fuel leak, not on the tank though. Guessing the lines.
Where can I get all new fuel lines including return lines and steel lines? Will I need any special tools?
sounds like you just need a return line kit. You can try to tighten the steel nut above the plastic cap but dont turn it too hard. If it is loose, there is your problem. I would consider a fuel return line kit, it has the orings, tubing, clamps etc etc. Around 30 bucks or so. if you lost 3/4 tank on a return like leak, you would have to notice a massive amount of fuel on the ground when you park and significant fuel smell when driving. I would look it all over. Check it all the way to the tanks and make sure the lines and connections are dry they whole way.
