Has anybody got a pic or ideas of how you secure the fuel tank with ali straps.

Ali straps will crack fairly quickly, try and get some stainless. Waste from the back of a fabricators guillotine is always a good bet

why not use nylon straps they fit better won't crack, and come come with a self tightening buckle,and no problems with sharp for the s.v.a

Hi, Not an MK but im sure my MNR is pretty similar. Ive got pics of my ally staps in the blog, link below.

I used ratchet tie downs (of course modified in length) they work brilliantly and I covered them with some Air conditioning insulation hose. You can tighten all you want and will last very long too.

If you're determined to use ali straps it's not that tricky.

Get 2 lengths of 20mm*2mm (? I think that's the size!) from B+Q, bend it to shape, stick some self-adhesive foam on the inside of it, couple of bolts through the end into chassis rail (or special tank mounting plate if the chassis maker has been kind). Job done.

On the STM / Aries tank it's even easier. The bottom plate of the TIG'd ali tank is wider than the tank and it's pre drilled for bolts. So you just bolt the whole tank onto the chassis. I wondered if petrol foaming would be a problem (after all, no isolating bobbins or anything) but no problems so far...

Hi bolting the petrol tank direct to the chassis is a bad idea. In the event of an accident it would mean that the tank has no choice but to get ripped off it's mountings. Hence why all most all manufacturers use straps of one kind or another. So the tank is not directly fastened to the chassis.

Second B and Q steel strips.. Just make sure you don't bend too tight a bend as they will crack (i.e. bend over something with a small radius in the vice.. I used old bike inner tubes for instead of foam (they were locost after all...)

I did'nt fancy ali ones, not sure they are really up to the job not sure if over time they would crack from vibration or not.

I would post photos, but my tank and chassis is not standard, it has locost style rear hoop with vertical stays at the back, so the straps only need to go half way round the tank.

The safest thing surely would be a catch which in a crash released the tank so that it may be ejected from the car by a large spring, that way it could burn all it wanted without endangering the driver.

Hi, i used tank straps on my indy, picture below on how i did mine:

Thanks or is it tanks you guys, anyway as usual, brilliant and helpful advice.
Cheers Barry

i asked mk the same question and they just PU there tanks to the chassis altho i used some 4mm aluminium 2" wide bolted to the two rear steel plates then bent it round the tank.
all the best
