So, I'm following Lindsey's fuel line upgrade to the "T"...

I got the plastic wheel cover off inside the wheel well (total bit$%) and then opened the hood and went to work getting the lines off the damper and FPR.

I started with the damper line - used two wrenches to hold the big nut steady while I loosened the fitting and as soon as it came just a tiny bit loose gas comes spraying out. I thought it might just be the built up pressure since I just drove the car a few hours ago, so I tightened it back up and then stuck a bunch of rags under there and then opened it back up again. I left it open for about 15 seconds and the pressure never subsided - it soaked my rag. That can't be right. Am I missing a step somewhere to make sure the gas is not shut off?? Certainly you don't have to empty a half gallon of gas in the engine to get these lines off??

 

Depressurize the rail by pulling the dme relay and cranking the car.

 

I just unscrewed the supply line, wasn't too much in there.

 

Just so I know... how does that work? I was thinking (don't say it, I know) that as vacuum falls with engine off, the regulator ports more fuel to the return line and hence less pressure in the rail. And I realize that no dme relay means no more fuel coming in, but how would cranking the engine help to reduce rail pressure? Bruce

 

Oh yea, duh, forgot about those pesky injectors...Bruce
