I am trying to decide between installing a sump or a draw straw i know the draw straw is the cheaper way to go but it seems like a sump would help with flow because gravity is helping rather than fighting the cause. Im planning on doing an air dog or similar lp soon so im just trying to line out supporting mods. thanks in advance for any input.

 

I tried the sender modification....Didnt work, too much "rigging" involved in my opinion. Im now running a straw and haven't had any problems. When you get below a quarter tank it can be hard for fuel to get to the straw with it sloshing around. If you keep your tank filled most of the time, run a straw.

 

Plus no real gain comes from the sump, if the pump isn't mounted below the tank as well. Idk why everyone has issues with their draw straws I've never had issues with the truck losing prime from acceleration, deceleration, low fuel level.
