I have a 1970 c10 with a 1984 350 in it. I rewired the truck and relocated fuel tank to under the bed. I ran the truck after I wired it and before I started the fuel system and everything was fine (I don’t think fuel caused anything, just noting that it happened very suddenly). After I got fuel lines ran to new tank, I turn it on, and it gushes probably 2-3q a minute out the back top of engine and streams down bellhousing. I was searching for half an hour and couldn’t find where it would be coming from, I’m not sure if anyone has had this issue, but hoping for some insight if anyone knows. TIA

 

Welcome from Florida. Sounds like it is coming from where the fuel line connects.

 

Title says oil, post suggests gas - which is it

 

I’m sorry, I should’ve been more clear, it gushes out 2-3q of oil a minute, I only mentioned fuel work because I was giving a timeline. I also can’t run it long enough or reliably enough to really see the oil come out, I will be getting a good few quarts soon to keep it topped up and maybe I can see.
