DIY fuel filter change MCS
Compliments of Eurothrasher @ northamericanmotoring.com
1) New Filter and gasket and O Ring kit ( Purchased mine from Atlantic British at Minicarparts.net - for about 38 bucks.
2) 10mm socket
3) flat bladed screw driver
4) rubber mallet or light hammer
5) Small angled hook tool to remove small O-Rings
6) Old (clean) Turkey baister
8) Rubber Gloves
9) Plastic Covering - to Cover the area working to protect from gasoline drips ect.
The Fuel Filter is located under the back passenger side seating area. You need to pull up the lower portion of the back seat, Front comes straight up, the back releases when it is then pulled forward.
Find the large black Tank Cover lid. Cover the area surrounding it with duct tape and thick plastic. You dont want the inside of your MINI stinking like petrol when we are done.
Removed the five 10mm nuts with socket, pry up the panel exposing the top of the entire sending unit. Some Chipmonk left me a gift on mine Vacuum any debris that is ontop before proceeding....
Loosen the Locking Collar Ring with flat bladed screw driver and rubber mallet, gently tapping until the ring moves freely enough to remove by hand.
If you are able to remove the ring then proceed to cover the fuel line connector with rags, and press the green side tabs INWARD and pull the connector out. A little petrol will come out under some pressure, but not a big deal.
Remove the metal locking ring, and secure the fuel connector aside and out of the way with some duct tape..
Gently pry up the Entire Sending Unit, Remeber it is sitting in a fuel tank....NO SMOKING PLEASE
Gently Lift the unit up about 3-4 inches ONLY, grab the top with one hand and the sides with the other and twist to unlock the top and pull the cap off. It was not easy, and you have to be careful of the various things attached to the bottom part ( sending unit arms and stuff ) Some of it is made of (breakable) plastic and you dont want that stuff falling into your tank !!!! I used a rag wedged in between the unit and the tank edge to help keep it in place.
After separating the top from the bottom, gentley place the bottom back, and remove the top and the filter should come with it. Carefully remove the old filter from the cap and dispose of it immediately in old coffee can or something similar. That black fuel can make a mess.
Remove the Large thin O-Ring and using the turkey baister suck the blackish fuel from the inside of the bottom assembly exposing the small O-ring and center post. ( please dispose of this old fuel properly
Remove the small O-Ring from the center post with a small hooked tool. Mine was somewhat brittle enough to removed by just picking at it.....But make sure to remove any small pieces that may fall to the bottom of canister.
Remove O-Ring from inside of Cap too.
Break out the Lube - Cover the new O-rings with a small amount of Vaseline before installing them.
This particular Gasket ring has to go in ONLY one way, Make sure you put install this with words " THIS SIDE DOWN " facing down into tank.
Pull up Canister from tank a few inches, holding tightly - press the new filter into bottom half with slight twisting motion. Then press the canister cap on the same way and press the two halves of the canister together, and a short twist to lock them together.
Slide the Gasket seal down ( with words " THIS SIDE DOWN" ) and press into place with your fingers, working them around the assembly until the gasket is flush
Place the canister in the tank with the lid tab lined up with the tank collar
Twist the metal locking ring back on hand tight, then securely with flat blade screw driver and mallet giving it a few taps to snug it up good ( Do not strip it, it should just snug up about 1 inch further or so
Push in the fuel line unitl the green locking tabs snap in place. Refasten the tank cover with the 10mm nuts. Remove plastic covering and duct tape, place a label over the lid with mileage and date of Filter change, secure back seat into place.
Place your key in the ignition and turn to positon 2 then to the off position about 5-6 times. This will re-pressurize the fuel system. Then it should start right up. Just for the heck of it, check under your vehicle for the next few days for any leaking fuel from that area. Mine was bone dry, but I was very careful and took my time with everything I did.
This was my first time and I was done in one hour. I should think it could be done in half that time with this experience.
My MCS now starts up first time everymoring as well
