Guys I am about to install my right hand tank and my mini obviously didn't come with standard. Does anyone have any advice. I was going to make a stencil of the existing hole basied on a few reference points and basically flip it over. Any advice much appreciated.

Yep good question I have always wondered about this myself ...

Also what do you recommend to cut it out with?

Maybe even someone will be kind enough to measure theirs and let you know so as you get it exact ..

thats how i did mine matt, just exact spot from the other side. I just used a nice new sharp hole saw and it turned out great.

I did it that way too- but marked it, drilled 1/4" holes all around, then hit it with the die grinder.
put a shoebox or rags inside the boot to catch all the swarf....

Dito

Same here and it turned out GREAT!

Yeah thanks guys that's what I thought. I had a go this arvo. I ended up going the same route at Doc. It won't win any beauty award but I nailed it as far as location is concerned. Thanks for the advice guys. Also I cleaned it up a bit more than in the photo...

OK the way that I did mine:

1: Measure the closest point of the LH hole to the seam and then the closest point to the pressed step above the hole.

Go to the other side and draw straight lines along the body the measured distances with a crayon or pencil.

2: Measure the LH hole diameter and set a compass to the correct radii.

Go to the other side (RH) and work the compass centre point around till the pencil on drawing a circle just touches the two previous drawn straight lines. This located the hole circle well.

3: To cut the hole I needed to maintain a tight cutting circle.

Got a hack saw blade and ground it down so that the teeth had about 4mm of metal behind them instread of the 10mm, did this for about 25.4mm of the length of the blade. Wrap the rest of the blade in rag to be able to hold it without slicing my hand open when cutting

Drilled a hole through the panel within the circle drawn. The hole was close but not on the pencil line.

Insert the hacksaw blade and started cutting.

A: I snapped the blade several times
B: I filed the hole when finished to remove the rough edges.
C: I put some gal primer on the edge to stop rusting.

In hind sight a slightly bigger hole is better then a smaller one when it comes to inserting and locating the tank

MOUNTING the RH TANK

1: Foot mounting and back rest mounting were taken from the LH side and used on the RH side. Found a donor car for components. Using a chisel and drill, drilled out the spots and chisel off the mounting brackets for a LH tank.

2: Located the floor mounting bracket on the RH side in the same orientation as the LH one. Was going to Drill through about 8-10 1/8 holes and pop rivit it in place. I actually cleaned both bracket and floor and weld it in place, remembering to gal prime before welding.

3: Same deal with the bracket mounts onto the back of the seat, just remembered to rotate it 180 degrees. Its was quite clear when look at.

4: Drilled a hole through the back seat and place a nut for the tank strap in the relative position to the LH side. Did'nt worry about the indent in the seat as seen on the LH side one. Fixed nut onto the seat with tack welds (was thinking of "sticky tape" and a nyloc nut)

5: Same deal for the nut in the boot floor for the tank strap as the back seat nut. Access to the underside was fun but I got there.

6: Finally fitted the tank with lines and breather, and the strap. The strap looked a little short but this is because the back seat didnt have the indent pressing as the LH side part does. Used longer mounting bolts and centre bolt to cope.

Finished job looks neat once I painted everything black

Note that with twin tanks (as on cooper S), each of the vent hoses should be run across to other side of car. Reason- if parked on a lean fuel can flow to the lowest tank then siphon out the short vent hose..

Cheers Besser, Doc. It's the little things that both of you have raised that makes a forum like this so useful. I am pretty happy with the hole and have compared exactly the you described Besser and she is pretty much spot on. I think I will take your approach with taking out the LH Strap and copying that. Doc will take your advice re the breathers, great info.

Cheers Matt
