Flexible ac hose

I am attempting to install vintage air condenser on my 51 chevy pu. The hard lines in front of radiator will not line up due to fan. I cannot put fan on engine side due to space between pulleys and radiator. Does anyone make short flexible lines I can purchase. I do not want to try and make these.

How far are you off?
Most of the lines are aluminum. You could cap a end, fill it full of sand, then cap the other end, to make a gentle S bend to walk the line over.

Just need to mske sure you got all the samd out after.

If you know the fitting sizes, there are places online that make up a flexible barrier A/C hose with whatever fitting sizes you need. Like many online purchases it can be relatively expensive once you add shipping, but its a simple task for a company with the right equipment.

I was lucky and found a local A/C shop where I could drive my truck over and they measured and made the hoses I needed as I waited. I have also read that any place that can make/fix hydraulic hoses will have the crimper needed to install A/C hose fittings onto barrier hose.

IIRC, the most common fitting sizes are #8, #10 and #12 O-ring fittings.

You don't show a location, but "pusher" fans are much less efficient than pullers. Especially in the southern half of our country. I'd spent the time and effort to correct this before proceeding. Shouldn't be too hard in large engine bay such as you have...

I don't think there are any flexible ac flexible hoses or fittings but you can add a fitting on to the end of what you have to extend and redirect the connection. On your fan situation, I attempted to add a pusher fan when I installed my ac. I already had an electric puller fan installed due to space restrictions on the engine side. My temps went up even when both fans were on and didn't matter if the ac was on or not, still higher temps. I removed the pusher fan and found that my temps dropped back to normal and all I needed was just the one puller fan inside with the ac or not. The puller fan tends to block normal air flow through the condenser coil and the radiator. My ac is even cooler. Lesson learned.
