Welding - Near fuel lines

[Gizmo.Y]

Ive got some small patch work to do on the inside of my car.

Its nothing major, But could do with some attention. The main issue is, the part i need to welding, the fuel line comes with 2" at closest range. There is zero room to move the fuel lines. and its a 3-4 hour job to move them (Dashboard/ Heaters out, Drop the Propshaft. Drop the tank - Hope the Banjos are not corroded...etc) to do a 1 minute job.

I'm talking approx 12 Plug-Welds and that is it using a Gas-Mig

So, im looking for some advice at shielding/ covering the lines as much as possible.

Would some Heavily soaked tea towels be sufficient? or is something more worthy recommended?

slide a piece of steel over them to shield them

Leather welding apron?

id go with a sheet of steel...no chance of it burning through

its not recomended to weld through them, been there done that twice.
1st time it sealed both sides of the plastic pipe didnt know until car ran out of fuel someone was supposed to be on fire watch, second time a lovely cascade of flames

Lukily, My Fuel lines are Metal. And there is no smell of Fumes. Im just worried a couple of sparks on there and BANG!

sparks touching steel lines wont cause a problem as long as the lines are not heated or holed by the weld you will be fine

Wet rag, bit of sheet. should do the job.

I have done that a few times, last time was I think a volvo[the copy of a daf].
I suddenly smelt petrol and saw light out of the corner of my eye. A big lump of spatter must have rolled along the floor and melted it's way thought the nylon fuel line, The line was covered by a bit of sheet. A but of petrol had obviously leaked out to start the fire, but it had burnt off and the spatter had sealed the nylon line.

Ditto that, bit of old towel.

i normally just put heatproof mats over them or use a welding blanket just to cover em and keep the heat away, shud be fine though

Yes, and as someone mentioned previously it is always a wise move to have someone on hand firewatching with an extinguisher - with the mask on you will not see if a small piece of carpet/sound deadening materila etc. catches.
