Fuel Regulator Question

Ok so, my car seems to be flooding itself more than a 13b normally does, usually starts first try and then after we kill it i wont start again for hours! i know if you have a bad fuel reg that gas can come up through the diaphragm and get into the vacuum tube / intake and cause flooding, so my real question / problem is i have a line that starts from under neath my injectors and leads to no were with a piece of tape that says "Fuel Reg", but my actual fuel regulator already has every line ran to it, i think maybe the vacuum tube that plugged into it is not really the vacuum tube and the line i explained earlier is the right vacuum tube, i will supply pictures and any help would be awesome!

Sounds like you probably have two problems - I doubt the fuel regulator is causing flooding, but you probably have some plumbing issues - old and leaky injectors tend to be a cause of flooding.

Look like he has a GSL-SE (1984/1985).

Post this in the First Gen section and it should get more traction.
