97 Blazer 4.3 csefi. My only 4x4 having a winter storm only way in/out 25 mile to town is 4x4, and so far not able to get home before dark. She was running great, and my last trip home smelled gas, this morning, smelled and heard gas pouring down from firewall behind dr ft wheel. She was hard to start but did start, I can see gas spraying from around the dr rear corner of eng, spraying all the way to under the booster, but haven't found the source yet. I'm going to have to fix it in the front yard in the snow over this weekend, trying to figure out cause and parts needed when I get a ride in with my son, so I'll have it here over weekend to repair. I'm assuming the fuel supply line, has anyone changed one, and can give advise on fastest, easiest was to fix it?
Thank you.

with mine iv gotten away with cutting the line flaring with a double flair tool and using rated fuel hose. its not recommended to do this but if done right it will hold iv been running mine like this for 2 years no issues. you can rent the flair tool from most autozones make sure to get a tubing cutter to.

 

Sounds like its coming from the fuel line test port. There is a small threaded bullet shaped port that will be pointing straight up. Inside there will be what appears to be the core from a tire fill pin. That's the shrader valve. It unscrews with a small tool. When they start to go sometimes a mechanic will putt a core from a regular tire in but they don't last cause there not fuel safe. The rubber get's eaten away. In a pinch you can do the same but make sure you replace it with one that is or the same thing will happen. I started a nice fire in my engine bay.
Look on youtube for fuel pressure test for Blazer if you can't find it you will see were they put the pressure gage and that's what your looking for.
