I've been smelling gas lately but I've kinda just figured its because I have no cat or tailpipe and a header, but it smelled more like raw fuel than exhaust fumes.
For some reason, I usually only get about $20 in gas at a time, but this morning I got $30.
A while after I got to work I walked past my Jeep and saw a bunch of marks on the ground under the fuel tank, looked up to the gas tank 'skid plate' stock cover thing, and I see a few drips hanging off. I grab one and smell it and its definitely gasoline.
I'm thinking maybe since my Flowmaster points at the front side of the tank, and since I have no tailpipe, maybe the heat from the exhaust warped the fuel tank some, or made a small hole in it.
I plan on starting to drop the tank this weekend when I have time, or at least start on doing that and see if I can find the problem....
Worst case scenario being I need a new tank, how much would this run??
Depending on where you get the "new" tank from it can cost you a couple hundred. If you are taking the tank off, be sure to check all the hoses and replace any that are cracked... it could be as simple as an old hose. Make sure all the clamps and what not are secure as well.
A friend of mine did exhaust work and it melted his tank pretty darn good. When we dropped the tank, it was about a 6" long gash and about 3" wide. Needless to say, he swapped the tank.
Keep in mind, gas and its fumes can be flammable. Do you really want to risk a fire or explosion due to your exhaust? Get it fixed ASAP!
Dropping a tank is no biggie, esp if you have a floor jack. Unhook the fuel lines on driver side, loosen all bolts (3 or 4 in back, 2 in front of tank). Get jack directly underneath and centered. Have it touch tank. Remove bolts. Keep tank steady, then lower straight down.
Try to keep it close to empty when you drop it. Also, be sure not to wear those satin undergarments your g-friend gave you for Valentines Day. Static electricity is a huge concern even with a small amount of fuel.
While you are at it, change your fuel filter since you have the tank down. If you're pushing + 100K miles, IMO - change the pump too before you install a new tank.
If your exhaust melted the plastic, there is a good chance you have bad chemicals in the gas from that altered plastic. The new pump, filter, setup is probably a wise thing to do, but if funds are tight, at least see about putting in a new filter.
I'll see whats up when I take it all apart. Thanks for the help guys..
But today another problem arose.
My 'BRAKE' light on my dash, letting me know the parking brake is on, is now on, after I never messed with the parking brake. The pedal goes almost to the floor, too.
I think thats a whole other thread...
Damn these car problems!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!
We'll see what it all looks like when I take it apart. Anything particular to watch out for when I'm dropping the tank? I'll try to drive most the gas off before I drop it.
I've done fuel pumps on 5.0 Mustangs and you have to completely drop the tank as the pump is directly on top and theres no access point from the trunk. It shouldn't be any more difficult right?
I had a leak on my 94. It was the gasket between the tank and the fuel pump assy. Only place to get the gasket was the dealer as all the parts houses around me would only sell one with the new $200 fuel pump.
Biggest ballet was the vent lines on top of the tank. Then trying to get the whole thing up and reconnecting the filler hoses.
Your Brake light might just be warning you that your master was failing, it's on the same circuit i think. Chevys are like that my heep has been pretty good lately just a damn squeek i cant find in the engine.
Becarful with that gas when you pull that pup out.
