You've got 2 fills? The 90° you might regret... impossible to fill with a pump nozzle at any rate of speed. Splashback is inevitable. In any case, I had a 90° on the red car which I removed when I changed the tank. It was a piece of steel tube that had been cut and re-welded to form the 90 angle. Flexible hose came off both sides. That would be the logical choice here rather than trying to bend inch and a quarter rubber hose to where you need it. Depending on the room you have to work with, even pre-bent conduit corners would work.
Just 1 fill but it'll take 2 bends to get it from the filler cap to the tank - poor wording choice. After posting I felt dumb not thinking of metal. SS or galvanized are the 2 top choices as anything else I'll have to cost to prevent corrosion.
Sweep is what it will be vs. the tight 90. Going to simply mock something up with PVC and see what an exhaust shop will charge to bend it up.

Bullshit!
Manufacturers put a check valve in the filler neck to prevent this from happening.
Put one of these in the filler neck and if the tank is vented properly you should have no splash back
First pic is from a mustang and second is a subaru
Aren't those check valves only to prevent splash back once you're done filling up? I took the 90* comment as if it's right where the nozzle of the pump is gas will splash back off the 90 and out rather than flowing nicely into the tank.
Either way I took some time and mocked up some PVC this weekend. I am going to get some galvanized or SS bent up and be done.

^ Yes, that *laugh*. For those of us who had cars that were built in the 70's without the modern valves in the filler pipes...

Just finished (I love that word) fitting my filler and it is a dog leg in silicone, a 45 degree x 45mm on the tank and a 45 to 50 reducer x 45 degree on the filler neck with a connector, I had to trim 1 1/2" off each so it all lined up in the middle but neat install if I say so myself, cable ties at the moment while I wait on some stainless jubilee clips. Also a 1/2" breather. *thumbs up*

Sorry for the misunderstanding.
I just assumed that since this was being built now and not back in the 70's that you might want to add these items that would solve any concerns of gas splashing back while refueling that was common back then.
Sorry just trying to help
My bad.
Mercedes not only has a tight bend coming out at the opening but also the pipe is reduced in size quite a bit and they have no issues of splash back.
Also putting in a baffle will help prevent splash back at the opening
In my RC airplane days I recall that with the glow fuel engines we used silicone for fuel line and with gas engines we had to use rubber fuel lines because the gas attacked the silicone.

Yep, listed as suitable for the job.
