Oil Cooler going!!!!
Discussion
Whilst refitting my gearbox this evening my thoughts turned to the packaging of my l/h (UK passenger) side pod above the fuel tank.
In that area I have an air-to-oil cooler and my fuel swirl tank, HP fuel pump, filter, and regulator.
I have also got an oil-over-water oil cooler and water temperature is never an issue. The air-to-oil cooler doesn't have a fan so is only any value when the car is in motion. In motion temps are never an issue. Fuel temperature has been in the past though.
My thoughts are that the air-to-oil is doing very little to cool the oil/engine. It is contributing to heating of fuel. I can blank the fittings to the cooler and route the oil return direct to my dry sump tank.
This is easily reversible if needed, but I think it will prove unnecessary.
Any thoughts - please remember I have the oil-over-water oil cooler though.

PS. If this works I will probably build a swirl tank with an integral HP pump, filter and regulator to cut down on the plumbing.

I don't see the value of two oil coolers, so wouldn't see an issue in removing one of them. I doubt the cooler itself is heating the fuel pot, as there's much more heat generated by the nearby engine & exhaust.
In my Can Am, I only have a standard air rad-type oil cooler and the unit itself doesn't radiate much heat. The car runs 60-90 degrees of oil temp (depending on whether it's cruising or hooning) and has only gone towards 100 in extreme heat or on track. With much less space under the Can Am clamshell, there is more heat build up, but neither oil or water have ever been an issue for me.
Why not create a blanking plate between the cooler & fuel swirl pot, that directs half the air coming in from the side pod to hit the fuel pot and the other half to the oil cooler and see what difference it makes? I'd continue the heat shield around the fuel pot to blank it off from the engine too.... maybe wrap the pot in some heat reflective material too? Of course, this is the wrong time of the yr to test temps with any certainty, you'll need our little island to warm up a bit first
A final thought... are your fuel rails returning excess fuel to the swirl pot? If so, that'll contribute to fuel heating too.
