Best way to blank off injectors?

[Gary]

old thread i know

but about that petrol tank idea, a mate and his cousin tried that with a GQ patrol as the tank was fouling something when it was lift kitted (i dunno what it was) so they had the idea of taking the tank out and cutting and welding it to suit then jamming it back in

they removed it, drained, filled with water, drained it, cut it, then when they were ready to weld the thing went bang

i saw the aftermath, quite nasty burns up one of the arms of mates cousin

welding puts quite a great deal more heat into things than just grinding i know, but be aware that theres still a risk of some bang action

Saw the same thing as Gary once, Tank was filled with water and had oxy waved over the filler, small crack fixed (on filler neck) and water drained, The boilermaker went back to redo the weld, because he wasnt happy with it, around a fifth of the water had been drained by this time, Bang.

A while after this a mate was cutting the tops out of 44 gallon drums (with an oxy) that had been used to store petrol. He wasnt going to worry about filling them with water first, I insisted.
By the 3rd or 4th drum he had caught up with me, and being a moron said "we dont need to screw around, this is taking too much time (to fill the drums)" and sauntered over with the lit oxy, as he waved it over the drum, I hit the deck.

The high pitched whistling sound as the expanding gas tried to force its way out of one little hole was scary. the top of the drum was domed upwards, and the mate stopped being such a gung ho dickhead........ for a while.

fortunately no one was hurt.
