2G Relieving Fuel Pressure with a bad pump?

[SkinnyBAM]

My fuel pump is dead and needs to be replaced. How can I relieve the fuel pressure?

 

[FORMONTOYA]

The easiest thing if replacing the fuel pump........take a rag and wrap the fitting that's underneath the car where it connects to the hard line. Then "crack" the fitting loose. The rag will "catch" the fuel and keep it from spraying anywhere. It will "relieve" itself fairly quickly with minimal dripping.

Just put down the cigarette (if you smoke) before you attempt this procedure.

Open your Gas Cap.

Open gas cap and if the car has not been running for a while you should be ok. I always put a rag on the top of fuel filter and releave it there.

I have the gas cap open and the car hasnt started in over a year thats why I thought I should be fine but when I pulled off the rubber hose on the pump gas came pouring out. Could this be because I put a full tank of gas in there?

Yeah I always open the cap and put a rag over the top of the fuel filter line and crack it. If you can, open the cap, then pull the fuel pump fuse or connector(or if its not pumping at all), then crank the engine a few times, that should get rid of most the fuel left in the lines.
But please yeah, Don't SMOKE! I helped my buddy swap and build his honda d15 engine, and I caught him about 5 times with a lit cigarette about 2 inches from the fuel line(with a dampened fuel papertowel). SCARY. I went and got my fire extinguisher, haha.

Yeah, everyone has pretty much nailed it
I had to do it the "champagne cork" way myself a while back - just have a rag (and preferably a fire extinguisher) handy and wear protective eye gear and gloves; as would be standard procedure every time you're working near the fuel system. Some fuel will spill out, but the pressure should "relieve itself" pretty much immediately as soon as you crack one of the lines.

 

[SkinnyBAM]

Just "cracked" the line and punched myself in the face because of the angle I was laying at very fun...

Do I need to drain all the fuel? Gas was still coming out of the line when I went back out there.

Since the fuel is old drain it all, and get new gas, and pour it in the tank, and let that filter through the lines, so all the old crappy octane dilluted gas is out.

I mean before I remove the pump. It was pouring out when I pulled off the rubber hose and then when I cracked the line it was also. Shouldn't there be no gas flow since the pump doesn't even turn on?

 

[fourreGsixty3]

I would think some sort of vacuum was formed when opening the lines. Lets see what others say.

Ok so I completely pulled the line off and put a milk jug underneath. Its been dripping at a steady rate for 15-20 minutes. Is the only thing I can do is let it drain the tank completely?? It doesn't make sense to me that theres this much fuel in the lines when the pump doesn't even work.

You can have a somewhat "siphon" effect coming from the hose being lower than the level in the tank. I'm sure you're done by now and have figured this out. But this is where a couple more rags comes in handy. Wrap the fitting on the pump assembly and just un-screw the hose. It will stop draining as soon as the hose comes off.

It's a messy job and you WILL get some gas on you..........that's why I mentioned to put the cigarette out. I too have seen some scary moments regarding smoking and working around gas/flammables.

It actually got too dark before I could finish it but I will try to get it done before I have to go to work today and let you know. That was the one fitting I didn't undo. After letting it drain out the line on the bottom of the car for a while I pulled off the return hose and gas was still pouring out.
