Is it safe to drill a fuek tank
hi now i got my sva out the way i want to sort the fuel sender but want to fit a electronic one in the top of the tank as original escort one stopped
working which was in the side.
is it safe to drill a hole in the tank (after its empty) for the new sender before i go and blow myself up?
Thanks
Mark

I think most people would suggest a hand drill. Electric ones can spark.
Be very careful.

i'd flush the tank first or if you plan to use an electric drill so there's no fumes kicking about
using an air drill, you should be ok without so much flushing

Might as well remove it and give it a real good flushing as you will have to flush it afterwards to get the swarf out afterwards anyway.
Top be really safe you could use an air drill and fill it with water i guess.

if its is full of water and you use air tools no problem.
we drill in to full gasoline bulk storage tanks using air tools in work, industry accepted practice
disclaimer!! I obviously accept no liability if you do this. do so at your own risk

I think a good new sharp drill bit and some engine oil would be worth using also as this would be be about the last job you'd want a red hot
blunt drill bit grinding away

there are a few ways to remove the fumes out of a tank, here are two that I know of:
1) fill tank with water to the brim, then just open the feed part and as the water trickles out put a flame over the top of the tank (where you filled
in the water from) that way the fumes will burn at a very slow rate and the water coming out of the tank will take most of the shock of the burning
fumes.
2) Use exhaust from an engine to feed into the top of the tank and it will exit through the feed of the tank. The exhaust is CO so it will replace any
oxygen in the tank, fumes cannot burn if there is no oxygen. After you leave it running for a while (depending on the size of tank) it should be
clear.
Either way you do it, always fill it up with water while you work on it.
Good luck and take care.
