Default Fuel contamination

During lockdown stripped out fuel tank and rinsed through with water (not best) on our beetle, replaced fuel hoses and have done less than 20 miles. Checked new fuel filter and it is filthy so assuming original metal line is full of crap. Has been suggested a air line (which I dont have only tyre inflator). If I remove all fuel and pour carb cleaner in tank and suck through with suction pump would this work or any better suggestions as dont want to ruin gaskets/floats in Icts etc.

The crap in the filter is most likely to be coming from the tank, (fuel will lift more crud than the water did). You can confirm this by installing the filter directly under the tank (before the hard fuel line),safest place and prevents crud from even getting into the line.
A tyre inflator will blow crud out of the line, just do it a few times. I would disconnect the tank and blow from engine end towards the tank.
Carb cleaner shouldn't damage any carb components or gaskets.

Not very well though, esp if it's a 12volt emergency jobbie. Might be better off with a tin of mushy peas and farting down the tube.

It's not so much how much pressure it will generate, it's how much CFM it's got to back it up.

Something like this - https://www.machinemart.co.uk/p/clar...ir-compressor/

Will be a good setup for your workshop, inflate your tyres in a few seconds, blow gun to blow out carbs, fuel lines etc, paraffin gun for waxoyl etc, spray gun ok for very small touch up work only mind, you'd need a much bigger compressor for decent spraying. - but a small mains powered compressor is well worth investing in IMHO, if you're going to be messing around with cars.
