Looking for replacement oil filter hoses

I’m in the process of rebuilding the stock engine in my 40 Ford ForDor Deluxe. I’m having trouble finding new rubber hoses for the oil filter housing. I’ve struck out at two of the possible hose fabricators locally but have one more to check with. I’m looking for any suggestions as far as possible suppliers.
The hose specifics are as follows:
Supply Hose (from engine to filter housing inlet): 21” long; 3/8” OD; 1/8” ID, 1/8” NPT Brass Fitting on housing end; 7/16-24 Brass Flare Fitting on engine end.
Return Hose (from filter housing outlet to engine at fuel pump): 16” long; 3/8” OD; 1/8” ID, 1/8” NPT Brass Fitting on housing end; 7/16-24 Brass Flare Fitting on engine end.
 
I have a used FoMoCo remote oil filter with two related oil lines. One is 17'" long, the other is 24.5" long with a banjo fitting on one end. Is this what your looking for? Coincidentally Im packing this to go to Hershey. Let me know

If you are not looking for an exactly stock looking appearance; you could use # 3 black nylon covered stainless braid teflon lined hose, replace the fittings at the engine with ? NPT to #3 AN fittings and use 1/8" NPT to #3 AN fittings at the filter. Overkill for the pressure; but readily available.
 
I like to use Areoquip, the hoses used on big trucks for the last 75 years or so. Not for the purists, But they have a braided exterior "clothe like" look, old timey, and the best news is the fittings thread onto the hose so you can make them yourself at home with no crimper, and custom fit to length.
 
In 40 Ford moved the return line from the fuel pump mount to the front of the engine on the timing gear cover using the banjo fitting as shown in post 5 above and special hollow bolt with two brass washer for seals.
 
I used this on my external oil filter. The brained lines look great. I went to a hydraulic line repair business to have the brass ends crimped on.
