-------------------------
drain the fluid out of the tank -
remove the purge line -
unbolt it -
remove the electrical plug -
release the spring clamp - and slide it down the hose slightly -
pull the tank off -
I recommend keep using the spring clamp -
I just did mine last year. I siphoned the surge tank over the fender into a bucket (or gallon jug). Shove the siphon hose down a couple of inches into the hose at the bottom of the tank. Now when you pull the tank you won't get any spillage. Replace the tank and refill it.
appreciate the advice, Bass and Ranger. btw, I'm not impressed with the finish work on the new unit where it's seamed together. Lots of ragged plastic, melted pieces, etc. Not nearly as smooth as the piece being replaced.

WOW - very disappointing -
that's the first complaint I have heard about the Dorman tanks -
I've handled a few of the Dorman tanks, also have never seen one that was obviously bad looking. I have sold one once that split quickly and we had to replace it, but the guy is still driving around with it to the best of my knowledge. Maybe yours was the last one built on Friday before the plant closed for the weekend!
considering that I paid $63.23 which included the cap, and free shipping, I think I can overlook the ragged seam.
Just installed the new tank. The minor imperfections wouldn't have been visible from the top, but I went ahead and smoothed off the plastic with a Dremel. The whole job took only 20 minutes; would have been less but retrieving one of the nuts I dropped took 5 min. Dexcool/distilled water, fire it up and no more "check coolant level". As long as I was working on it, I went ahead and added a CF Performance chip, a turbo impeller in the intake, 1 bottle of octane booster & 1 of Seafoam in the gas tank, a K&N cold air intake, and filled the washer reservoir with dihydrogen monoxide. I figure my horsepower increase was +/- 0%

Just a heads up, to take full advantage of the electric turbo, it's recommended that you install fuel line magnets.
A sleeper is nice, but you should use some visual aids to warn surrounding drivers of all that extra power. Barbed wire pin stripe, stick on vents on the rear bumper, and a chrome plastic hood scoop, mounted slightly crooked and off center, will suit the performance mods perfectly.

Yup. I've personally seen those same mods add triple that!
You're so very wrong. To take full advantage of the performance "chip" you need to add a throttle operated solenoid that ports compressed computer air onto the chip sensor at WOT in order to further mess up the intake air temperature signal. That's what gives you the 73.6 hp increase above 2200 rpm in 4th. Sheesh !!
Lucas Oil Stabilizer on the Tornado fan bearing allows it to spin faster, increasing boost and fuel atomization. (Oooopppssss - it's a fuel injected engine. The Tornado compresses the fuel into big chunks so it burns better. My bad.)
I like to stuff abrasive ScotchBrite pads into the intake duct - that filters the air a second time and the abrasive aluminum oxide particles clean the throttlebody. A nice, oily K&N filter lubricates the air and makes it flow faster.

No shortage of excellent advice in this one guys :yup:
I vote we sticky this one!

If you didn't put the stickers on the driver's side rear quarter window you cost yourself at least 30 hp.
If the tank wasn't chromed it'll cost you two tenths right off...
the only stickers I allow on my car are a Longhorn decal, and the NRA sticker. The NRA logo alone adds at least 1200fps.
