Gas leak near Fuel filter...help...

I have a 95 Wrangler (4cylinder). I started it up the other day and while still in the garage (had only been running a few minutes) I had a strong gas leak near the fuel filter (it was almost pouring out, not just dripping). Once I shut it off, I couldn't tell exactly where the leak was coming from other than it was very near the fuel filter.
I ended up replacing the fuel filter, the incoming and outgoing rubber hoses (used the fuel injection hoses), and got new clamps. I made sure the filter was on facing the correct way and that the clamps and hoses were tight (but not over-tightened) and when I tried to start it there was still a gas leak and my Jeep wouldn't start. The leak was not as profuse as before but it was still a significant drip that made a large puddle within seconds of trying to start the Jeep. I looked under the Jeep and the only place where it was wet and dripping seemed to be where the hose on the "exit" side of the filter connects to the metal fuel line. The hose went up to the flared ring on the matel fuel line, so I would think it was on far enough and it was tight so I am not sure what to check next. Any advise would be appreciated. Thanks so much!

I'll get back under there and double check the clamps. I sure hope that is it. I tightened them pretty well though, but I didn't want to over tighten them. I was told that it could damage the fuel line if they were too tight.

are there any other things to check? Could there be a plugged/blocked fuel line? I am going to try to tighten the clamps down (which makes sense), but I thought they were arleady pretty tight.

Pressure at the rail? Dumb one but are you using the correct size hose material? If not you could be trying to cinch down on too much hose but not sealing against the hard line.

I took the hose in with me to Autozone and they matched it up. It felt pretty snug as I slipped it on the fuel line. Hopefully it will just be a clamp that I need to tighten back up, but I was worried because I tightened it pretty well,. I guess I need to really screw it tight (maybe I was too worried about overtightening it in the first place).

A redneck tip for you, where you suspect your leak-coat the area with something chalky (flower works, or ...chalk) it will give you a better idea if it is a gravity drip coming from somewhere higher, or the leak is right where you chalked it up. Here is what you should look for, If you chalk up a good 2 inches of the hose where you suspect a leak, if it is a gravity drip coming from somewhere higher...the chalk will generally fade away on the underside. If you chalked it and the leak is coming from an area close by, you will notice far more less (sic) chalk than you applied.

Good luck!
