On my 1995 jeep on top of my fuel tank there 2 /what looks like vacuum lines going to 2 plastic things/ how do i replace them or can i just plug the holes and lines

Hope this helps, good luck. -

Two lines go to canister. One is a ported vac and the other goes to the gas tank. When the engine builds enough vacuum it draws all the excess gasses back to the tank from the other line.

Sounds like either a leaky fuel regulator, or fuel injectors.

First of all, the fuel pump is generally located in the fuel tank, not always though. Yours probably is, in did not research it. The fuel electric fuel pump turns on only when the ignition key switch is turned to the start position and then left on. A series of one or two relays along with a pressure monitor in the fuel rail delivery system may or not cycle it on and off depending on design. Enough of that. I suggest that you remove the spark plugs to see if they are oil/heavy cabon deposits.If so, professional attention is reguired. One more thing you could try is replacing the spark plug wires. the may be old/worn out/damage. This would give the engine spark a stronger spark,if worn and also replace the spark plugs.

i'm pretty sure jeep had their pumps in the tank. you can phone parts place to double check. If it is in the tank, you will have to drop the tank in order to access it. Other vehicles have a latch or door thing that will allow you access from the top. pretty sure the jeep does not have this. you will have to disconnect all of the hoses and hopefully your tank is almost empty or else they weigh a ton.....then just take out the old sending unit, put on a new fuel pump and put it back...simplified version, but it will give you a gerneral idea. when i first dropped mine, it took me 1/2 a day, now i can do it in about 1.5-2 hrs

check all vacuum hoses look for broke crack vacuum lines.replace all spark plugs and wires.if they have been changed in a while.also clean fuel injectors using prestone or gum out .fill gas tank .put a bottle injector cleaner.in tank .drive it around several miles so the injector cleaner will clean out injectors.wait until car cool down .change fuel filter. relieve fuel pressure first before removing fuel filter.

I had a problem with a fuel return line that caused my 95 YJ to do the same thing. It was getting flooded after a few short miles, and would not start for a while. You can buy a fuel pressure gauge and check the fuel pressure, if the pressure is to high that might be your problem. I took my fuel return line off after checking the pressure and tried to blow thru the line with my mouth and could not. After dropping the fuel tank I discoverd that my skid plate was dented in, causing the bottom of my fuel cell to be pushed up and the end of the fuel return line (in side the tank) to be blocked. Good Luck, and if that ends up being the problem you may want to replace your spark plugs, they may have been fowled because of the excess fuel.

You MIGHT not have to drop the tank. On the 95 LHS (same frame) you can go through the trunk. take the trunk lining out. Underneath it near the back seat there may be an access panel. If so it will make it MUCH easier to replace! Worth the time to check it out!

its not real hateful especially if the tank is low on fuel....you need to drop the tank out of the vehicle....the electrical connecto is on the drivers side in front of the tank mounted to the frame,,,,disconnect the fuel lines and undo the nuts holding the 2 straps...lower the tank and there is a plastic ring holding the pump in...loosen it counter clockwise and remove the pump

Hello everyone,l

For those of you who haven't started removing the gas tank, I'll start from the beginning.
You will need a 1/2" socket, ratchet, extensions, flat head, needle nose, floor jack, rag, broomstick,. A creeper will make this easier. Depending on your dimensions and the height of the frame on your particular vehicle, you may be able to use it without jacking the vehicle up..

• Disconnect the negative battery terminal
• If your engine is fuel injected, you need to relieve the line pressure. This is done from the injector rack on top of the engine. About the center of the rack you will find what looks like a filler valve on your tire, only thicker. The fuel line can maintain over 40 P.S.I. pressure even with key off. Place a rag over the pressure relief valve. Use the corner of a screwdriver to poke the center core through the rag. A second or two should do it.
  
• Place a floor jack under the gas tank shield, jack it up until snug.
• Disconnect the rear exhaust hanger.
• Loosen and remove the three shield nuts above the rear end
  
• Remove the plastic shield from beneath the left rear corner. Two plastic anchors hold it on. Disengage them by pulling the center plug out about 1/2". This will expose the hoses connecting the tank to the body.
  
• Loosen the hose clamps
  
• If you can get them to twist, try and get them off.
  
• Rear nuts next. Loosen and remove all but the center one.
• Make sure the jack is centered and snug
  
• Remove the last nut. The tank isn't going to DROP. It will kind of lean, and jam against the exhaust.
• Insert the broom stick into the exhaust pipe.
• Push and hold it to the right, slowly let the jack down. Stop if it hangs up and work it free.
• When its down far enough to access the top of the tank, disconnect the plug, loosen thew hose clamps, remove the hoses, separate the vent hoses at the 'T' connector.
• Lower it the rest of the way
• The tank can now be separated from the shield.

If you were experiencing a line leak, the top of the tank is where you'll find it. Inspect hoses, gaskets and connections
