So to save a long story...I'm pulling an engine out of my 87 GT. Its down to a longblock with fuel rails, accessories are all out. I just remembered this morning that I FORGOT to relieve the fuel pressure. This is not my first fuel injection parts replacement( had to replace entire fuel system in both my 88 and 91 s10 lowriders), I just had a lapse of reason. Obviously putting battery back in, turning key, and etc. isnt an option(or is it?)

My question is, short of reassembling the entire engine, is the a plan B for relieving my fuel pressure? I was thinking SLOWLY/CAREFULLY remove fuel filter since I've got to do it anyway. Any advice? And please, I already feel like a moron so be nice!

Just pull the hard fuel line going into the rails. That's all I did...

Just keep your eyeballs away from it, no open heat source and have some shop towels to clean up the fuel

So ya still have the stock fuel rails installed? Just behind the alternator, there's a pressure valve in the fuel rail, just like a tire valve. Just wrap a rag around a screwdriver and depress it. All you'll get is a little spray of fuel for a second, no big deal.

If it's been more than a day, there will be no pressure but there will be a very small amount of fuel. I've had a remote gauge on mine for 2 days, pressure is 0 psi.
