totaly worth the wait.the only thing i really know about instaling them is to remove the standard tank mounts from the rear.

When i do mine, i try to leave as much packaging on as possible, to prevent scratching especially on the bottom. First step as you know is to remove the original mounting points, about the only way to do this is with an angle grinder.

Next thing to do would be to mark and drill the mounting points on the tank brackets, centre of the mount, i think it is a 1/2 inch drill bit, but you should have recieved the required bolts with the tank. Best to drill through first with smaller drill bit say 1/8.

Put car up on jack stands if you already havnt done so. The easiest way i found is to get a trolley jack and place the tank on top of jack so it is balanced, Then slide tank under car, then jack up till it is where it should be. then go round and measure from the tank to the rails etc , to make sure the tank is mounted centre.

Then its a matter of running the dril through the rails to mount it. Before fitting to the car finally, you will need to cut off the filler pipe from a donor tank, and mount that to the tank, and also the sender unit will have to be fitted, then bolt it all up, job done :spoton:

other members may have some tips also but this is how i do it.

Yeah, agree with mra9x. Fitted one of these tanks about 5-6yrs ago. I've attached some pics to give you a visual reference.

There's really no contest between the two tanks.

Take your time fitting up the tank, getting it square and remember, measure twice, drill once...

Don't forget to attach the filler neck with the supplied hose piece.

Not much clearance around the pipes.

The standard Torana fuel sender fits here. Don't forget to grease up the seal before fitting.

Sit back and enjoy the view. :spoton:

I used a 4" angle grinder to remove all the old tank mountings. Imho not much point in polishing what you wont see, aluminium oxidises to form its own protective coating so maybe just give the as-installed bottom and sides an initial polish.

I just used a bit of vasoline on the seal. I "think" you can get the seals from Rare Spares, but don't quote me on that. Yeah, I just used a pair of 2" rubber strips to insulate/protect the tank from the body. Simple but effective. :spoton:
