sounds like your diaphragm in the regulator has a hole in it

the fuel should only be going threw the metal lines to the injector block to feed the injectors. definitely not from a vacume line

Re: Throttle body/FPR lines
you can see the fuel and return lines only go to and from the block feeding the injectors
Re: Throttle body/FPR lines
Ok, so the fuel lines are the only wants that should be shooting fuel. Since there’s fuel in the vacuum line coming from the regulator, you mentioned there’s a hole in the diaphragm. That should be replaced. I’m guessing this is the reason it won’t start since it’s not getting the appropriate fuel pressure. What about the vacuum leak? Should I plug it? I don’t know where it goes. I should be able to get the new regulator sometime around Thurs and i’ll have time around Mon to install it, so hopefully it won’t rot in the backyard anymore haha.
