Screw all this half-assin', relocate it! There's a write-up on another site you can find by searching where the guy dissected the stock lines and moved the solenoid to where the AIR pump used to be. No CEL, no venting flammable vapor around hot surfaces, etc. I followed that write-up this morning and I'm almost done. I should have had it knocked out in about an hour, but I didn't have enough 5/16" and 3/8" fuel line hose to finish so now I have to wait til tomorrow to go get more line

But the write up made it a piece of cake, I wish I had done this earlier!
Edit: Whoops, didn't read the part about you wanting to reduce weight. If you took out all the stock line from the back to the front, yeah you'd lose weight. If it's the aesthetic part, relocate it.
