The tank has a incline towards the pick up. I tried putting baffles in my factory tank. I hit the perfect spot right where the metal was thin from rusting under the strap. Blew a hole right in it. The one in the pic was my second attempt. If I pulled it off the first time I would only have $300 in it. The pick up has a bread pan sized sump around it so I figure it wont starve if the return is pushing fuel back into the same pan.
