No it can not over pressurized. You probably nicked something and didn't realize it. You're going to have to find the exact source

Make sure the copper crush washes are in the top banjo bolt. That is where i would start.

OEM filter? I had a similar problem trying to use an aftermarket filter. Poured all over the place. I never had an issue. Swapped it out with a true OEM from ExtremePSI.com, and issue solved.

Im starting to think this is the case since it was working fine and leak free until i got my cursed hands near it. I just found it odd that the only part i even touched was the crimped line at the top of the filter (didnt disconnect, only slightly wiggling it), yet the leak seems to be from under the filter. I just hope swapping filters fixes it. Im assuming the "fuel in" side seals the same way brake lines do? no o ring or anything?

Correct.

Sounds like you're guessing and hoping. If you find the leak you'll know for sure and you can address it. Causing a leak by movement at the filter seems unlikely to me. Its a flare fitting on bottom and a threaded banjo on top. The top line is rubber with crimps and likely 24 years old. I would clean it all up then find the leak. Changing filter wouldn't hurt I just doubt thats the source. The connections should be fairly robust. See what I'm saying? Anything is possible but I like to be sure.

I see what you're saying and i agree it should be a notable event to cause it to leak i would think, but this car was driving around all the time leakless until i replace...... the starter???? Of all things the fuel leaks now? Whatever... after work today ill break out the ole flashlight and inspection mirror and get to the bottom of it. I just pray i dont have to run a new hardline or something. Ill update this the read when i locate the issue and get some photos. Thanks for the input!

I would think the rubber line leaking is more probable. Is there any rust? That could be a problem also.

Sounds like a final-straw situation, where something was old/corroded/deteriorated, and all it took was a minimal disturbance to start a leak. I would think it is not that hard to find, although running the engine with a fuel leak and your head under the hood is a recipe for cashing in your life insurance in a bad way. Perhaps try powering the pump with a remote switch to 12V, to be safe. I had to swap out my fuel filter an an O'Rileys parking lot (had to buy the wrenches, too), and the parts-store unit they sold me worked fine (externally at least, who knows how well it filters?).
As to your musing about fixing a started and ending up with a fuel problem; sounds completely normal in my experience. I can hardly attempt to fix anything on my car without something else mysteriously develop problems. It's kind of a corollary of Murphy's Law, I believe, similar to the laws of physics, chemistry and thermodynamics, and certainly unrelated to my wrenching skills.

Ok so i have an update. I investigated the leak and it seems i may have bumped upper line with the banjo bolt and rotated the entire assembly, essentially cracking the bottom "fuel in" line loose, causing the leak. I guess it was never all that tight??? I went ahead and removed the filter and the upper line since the leaked fuel seems pretty gross. I think ill go ahead and just replace the filter to rail line as well since its a crimped OEM connection that has been played around with a good bit at this point. I've attached what i plan to order below. Do these look to be alright? Thanks for the help guys!

Those do look to be the correct replacement parts! Like @Mech Addict, I have ran a parts store filter without any issues (on the outside as he also stated). I keep a couple spare filters in the shop that came from the parts store counter.

Ahh glad to see someone else is plagued with their own mechanical ability... and as an engineer, i understand laws beyond my control Thanks for the input

Thanks for the confirmation! Order placed.

That's what we are all here for, help!
You will love the filter to rail kit and it gets rid of a possible old hose that, god forbid, would leak enough to catch the car on fire so, maybe, just maybe, run down to WM and get a fire extinguisher. I have one in each one of my DSM's, as I had an oil fire from popping the dipstick out under boost and it went all over the exhaust manifold.
I was SERIOUSLY considering peeing on it but got dirt from the side of the road and tossed it on the manifold, whew. Bought a fire extinguisher that day!!!

Installed the kit and it is a leak free system now, and my AFR is looking normal! This braided AN style hose assembly is a way better alternative to the OEM style crimped rubber hose. I will say that unless you have relocated the battery to the trunk, you will want to trim the hose a few inches to keep it clean and not having your fuel line do a loop or run all over your battery terminals.
