This is my first real tech question on here so please take it easy!!! i recently sprung a leak on the rear fuel line into the rail on my new (to me) 91LC. I have had plenty of experience on older American V8s and inline 6s, this is my first smogged/ EFI motor ever. After literally climbing into the bay with the engine, I've narrowed the leak to the fuel line coupling with the rail. Not sure what size the nut is to check if its loose (i have a pdf FSM). is there any other way to check without pulling the entire intake off? Im not going to lie, the 300 hoses and wires are a bit intimidating. If not then i guess the best way to learn to swim is by jumping into the deep end. thanks for any response i get.
