its the line on the left......on the egr spacer? is this a fuel line? im new to 5.0 efi im an old carb lover but am learning,anyway car wouldnt start today batt was dead.Ive been having low volt problems just the last day or so.I noticed yesterday the heater picked up and lights got brighter when i hit the gas so i turrned off my PIAA lights,but have an unknown electric fan.Ive read with just the electric fan i need the 3g alternato upgrade? what it the 3g?Should i do that or get a good aftermarket brand? Heck im not even running underdrive pullies yet.....ok back o the reason for the pic and the long explanation....the line was spurting a thin stream out of the hose at high rpm.I was revving it up to help charge better and noticed it.should i get it fixed asap? could this be a reason for the sudden electrical problems?
