Hi Vic,

When you put back the tank in place, do you bolt it up, connect, fill with petrol and fire it up, or is there anything else or procedure you need to do?

Thanks in advance

Regards


Mario
Sorry for the delay in replying Mario. Fit the tank, connect everything up, double check and then put a couple of gallons on, switch the ignition on, wait for the pump to stop ticking, check for leaks then start up. If the pump doesn't stop ticking there's definitely a leak.

I did the same as Vic Butler above some 35 yrs ago and its still fine. A strip of compressible rubber eg rubber hose can close the gap along the front edge when installing to prevent road grit etc getting between tank and floor.
Always dip nuts and bolts in Waxoyl whenever reassembling everything. Bolts come out easily then even 40 yrs on and still have their shiny sherardised coating.

So I'm about to embark on this same project for my '78 GT. I've noticed now that at some point the rear part of the boot has been reinforced, I presume after some body repair work. The rear two bolts are not in place, with a L shaped piece of steel welded over the holes, and the tank being held in place with the remaining 7 studs. Should I go to the trouble of measuring out and re-drilling the holes to put the bolts through, or just not worry about it? Picture attached for some illustration...

Nathan, no picture attached as far as I can see? O think it would be essential to offer any views?

I can't see anything unusual in the photo, but my BGT is a '72, so others may be better placed to spot something.
I would say that the tank is best held with all of the fasteners in place, so if you can re-drill the holes and use all of the bolts, then I would do that.
