I read reviews on the vmaxx spacer that the fuel lines bend and won't clear the spark plugs on the distributor is there a solution and how much hp gains would the spacer provide and is it worth it?
The previous owner on this vehicle removed one of fuel lines from its plastic bracket underneath the truck. It seems that provided more freedom of movement. He may have done something to the fuel line closer to the intake manifold, but I have not been able to get a good look at it. I only noticed that he removed it from the plastic bracket because I was underneath the truck just looking around at the driveshafts, transmission harness, and other things, and I happened to notice that.
No idea on the HP/TQ gains.
In my opinion, not worth it because you have to bend, move, alter the OEM configuration to get it to work.
