Okay, long story short, the guy before me was a dumba** and took all the short cuts possible when it came to the truck, so now I am missing lines and the truck is leaking gas badly. If anyone else can post pictures of their engine bays, it would be greatly appreciated (My truck is an 88 w150 5.2L V8). So, here's the issues: 1. This piece is spewing gas when the truck runs. Not a trained mechanic, but my guess it that this is a return line or something of that sort. There was no hose connected on top or bottom, so I was wondering where this hose runs to? 2: On my carb (Holley 2BBL) there is a hose that runs off of this, and today I realized that there is a screw in the end of this hose. I'm 99.9% sure this isn't factory spec, so I was wondering where this hose runs to? Any pictures/advice is greatly appreciated. Thanks guys!
