Quick update, in case it happens to anyone else...

There's a drain nipple on the fuel pump that has a rubber stopper on it. About 130k miles ago, the stock one cracked and started leaking, so I replaced it with a vacuum hose cover from the parts store, secured it with a tie wrap, and went on my merry way.

Last week, I got really bad gas mileage (18 or so), and then noticed a strong fuel odor the next morning. Sure enough, the bandaid had finally let loose again. Back to a parts store, and 20 minutes later it was all fixed again, hopefully for another 125,000+ miles

 

i had that problem before on one of my old neons too

 

hmmm so that could be why i see and smell gas back there... well besides it being the gas tank that is lol. i only smell the odor in the cab though when i ran my Neon hard for a extended period of time.

 

I once sprang a leak from the fuel hose,it had gotten worn over time so instead of replacing it with more hose, I just cut before the spot of the hole and put it back on, sure enough it keep poping holes again and again, it only did it when the car was off at first and then when it was still running, ran to the part store and got a longer size hose and problem fixed.

 

Isn't there a permanent fix for this problem, I drain two tank of gas b/c the aftermarket vacuum caps don't last.

 

I used a rubber stopper I purchased from Ace and it has worked for about 3 years so far.
