Default new Raptor 150 & drawstraw leaking fuel?

so just got my truck going after putting in a raptor 150, draw straw I and the VP big line kit. my truck constantly has been leaking fuel from somewhere around the gas tank, havent been able to find the source. comes around the tank and drips off the bottom. i heard they leak fuel for a couple days bc of the old supply line? idn if thats wat it is its constanly dripping and when i filled it it dropped like a qtr gallon as it topped off. the old supply line is still all there and attatched at the old LP and is cut at the plastic by the top of the tank. its getting all over my rear and shock from driving and i need to stop it!! any help or suggestions??

When i installed my raptor 150 on my 2000 it didn't leak at all and i left all the old lines and lift pump in. so its probably something else.

You didn't cut the return line did you? Your gonna have to get up there and have a look while it's running.

i cut the supply line right behind the connector to the sending unit and when i put the tank back up the plastic return line was kinked so i replaced it w a new flexible fuel line. and i tried looking while running while hitting the throttle and cant see where its coming from. its all over my rear components and has a constant drip at the bottom of the tank
