Hey Dave, great looking product!

When your back after Chrissy could I trouble you for a picture of one fitted to one of our fine automobiles? 86 preferred, but happy with whatever just to help me visualize.

Cheers

some rough instructions

You will need fuel line about 1 or 2 metres the same guage as the brass fittings and solid fuel lines on your car and a small piece to go between surge tank outlet and inlet for the external fuel pump 8 small hose clamps wiring diagram wire relay etc external fuel pump I used a 2nd hand vl turbo one
a pair of nuts and bolts and a drill and drill bits to make two holes that these bolts will fit through and a drill bit big enough to drill a hole so the fuel tank strap bolt can fit through I think its 8 or 10 mm..


Basically get the rear end of the car up off the ground then you have to undo the bolts holding the straps that hold the fuel tank in place and drop it down.
Place the surge tank up under the car so the brass fittings are on top and pointing towards the middle of the car.
The bendable strap should now be bent up so it lines up with the bolt hole that the fuel tank strap bolt was in. Mark where the hole needs to be drilled so the bolt can now hold up the tank and the fuels tank strap.
Now get out from under the car and drill out the hole and get the brass fittings and get thread tape or fuel proof sealant use it on the brass fitting and stick them in the three holes at the end of the tank.
Get the fuel tank strap bolt and use it to hold the tank in position so you can drill two holes through the L bracket and through the floor (boot) of the car and use the pair of nuts n bolts to hold tank in place.
Now you will be able to see where you need to cut the hard fuel lines so you can plumb them up to the brass fittings using the fuel line and hose clamps. Now you can sort the wiring and put the fuel tank back in place.
You will need to have some fuel in the surge tank so the external fuel pump doesnt run with out fuel while the tank is filled by the intank pump.

If you look at it enough it will eventually make sense ;)

I will take a series of photos when I do the install in my car... which will probably still be a few weeks away :S

Hey guys, here is a segment from my SR build thread where I installed one of these, it includes a couple of things I would change if I installed the tank fresh again, so hopefully this should clear up any questions you guys have!

OK, to give people an idea of where these things go, this is the area without the tank yet installed:

http://i182.photobucket.com/albums/x307/commando_robinson/9F056C73-0FB3-4565-87C1-20FF65D1594C_zpslx9qhqkm.jpg

This is just under the rear driver's wheel well. You can see the tank guard plastic and the start of the panard bar from its little tower. The tank actually sits right up against the crossemember that the panard bar is anchored to. In fact, don't be tempted to leave a small gap between the tank and the crossmember as I did on the first attempt because the surge tank will then foul on the fuel tank when you try to re install it!

I suggest you drop the fuel tank and undo the hard line anchor point and get everything out of the way and then just play around a little with the surge tank until you are 100% on how it will end up sitting.

http://i182.photobucket.com/albums/x307/commando_robinson/4AAA3B94-5A6D-41F9-84EC-A648AD7DEBEA_zps5hqcq8vj.jpg

Once that is done you will see you need to bend the attachment arm a little in order to get it mount properly, but its a pretty easy job. Again in hindsight I would actually have bent it more aggressively to move the tank a little bit more towards the chassis rail for clearances.

http://i182.photobucket.com/albums/x307/commando_robinson/D95F205A-2C48-4795-B42A-BDFC23F35C29_zps9ortcejg.jpg

Then you just mark up points to drill some holes so that you can bolt it to the car. I ended up having to elongate my holes a little because I didn't have the surge tank right up against the panard bar support crossmember when I first fitted it up.

Once that is done its just a matter of fitting up your pumps and gear and then connecting the lines to the appropriate hard lines. As I mentioned earlier, my hardlines aren't exactly standard, so I'm not positive, but I would expect that other people fitting this surge tank will also need to bend the factory hardlines as they run essentially right into where your pump will end up sitting. I think mine is also a little further to the center of the car than is completely ideal as my pump practically fouls on the inner support strap for the fuel tank.

Anyway here is a completed picture of my fuel system and a diagram I made to work off before starting:

http://i182.photobucket.com/albums/x307/commando_robinson/2B44E866-1870-4834-881E-471182F9A7ED_zpssbbhnij6.jpg

Hmm just noticed a typo in the diagram, should be 044 in my case, meh

If so, do you have any updated pictures at all? I can't seem to see any in the previous pages.
