Fuel leak 1991 4Runner with 3.0

I have a fuel leak just behind thew front passenger tire. It only does it after I drive it about +/- 8m. Then it runs out a drain hole in the bottom of the frame. When I say runs I mean runs. Then it stops. The truck misses and buck while it is leaking. It runs fine before it starts leaking.. I can't see or feel where it is leaking to get into the frame. Anyone have any ideas?

 

I believe it's a aux in-line fuel pump. I loaned my old girl out, to a buddy of mine. He called one day to tell me she was piss'n fuel from the passenger side of the frame. He had a mech buddy, change it at cost. Don't remember how much I paid. Wanna say, $150.

 

Sorry. I checked my log. Fuel regulator. High pressure line comes up and goes to the regulator on the passenger side (of the engine bay). Hope this helps!

 

Thanks for the info

 

Possibility, If you smell gas in the cab, Check your fuel damper assembly. It's kind of in that area. I did, it was leaking, and I replaced it. Fixed.
