Replacement gas tank/fuel pump/filter?

So I need to drop the gas tank in my 2000 xj to smoke my evaporative system since a new gas cap did not resolve my evap leak. While I'm in there I would like to replace the fuel pump, fuel filter, and (depending on the price) the tank too. I just installed a rebuilt engine so having a new clean tank sounds like a good idea. Can I get these parts from the dealership? If not what are some quality replacements? Do they sell tanks with the pump and filter ready to go?

Wondering why you think the tank needs to come out for a smoke test ? Wondering why the tank would need replacing unless it is leaking ? If the tank has sediments, they can be flushed out, or wiped out with a clean cloth. The 97-01 fuel filter is not routinely replaced and will be fine unless testing shows it is clogged.

Buy a genuine Jeep fuel pump assembly or a Bosch. AirTex fuel pumps suck and you will regret buying one.

CJ-7 Tim offers good advice. I will also further comment that the tank on a 2000 XJ is made from HDPE (blow molded plastic) and unless it is cracked/leaking, it never gets rusty inside like a steel tank would. Thus, changing the tank is RARELY needed. If the tank actually has contaminants in it (dirt, rocks, etc.), it can be washed out sucessfully and allowed to dry.
WANTED--MJ Comanche to restore. Must be solid, (relatively) rust free chassis. Send me a PM if you have a line on one that is for sale.

If you have EVAP system leaks you may want to examine the steel tube that goes from the EVAP canister to the roll-over valve plastic tube coming from the top of the gas tank (tank removal not required). This steel tube has a bad habit of rusting out to the point that pin holes are formed in the tube that causes EVAP system leaks.

If this is your problem, the fix is to replace the tube with OEM or remove tube and replace it with 1/4" ID rubber hose. The only problem with you'll need a 1/4x1/4 barb fitting to couple the hose to the rubber elbow on the canister.
