How much pressure does the omp use
How much pressure does the omp use to send oil to the engine? I know Ben makes omp lines that are steel braided but do the have to be? Couldn't you just use small engine fuel line and some clamps to supply the oil to the engine?
Very low pressure. You can do this on the stupid cheap end of the spectrum:

I did it, and they've lasted several years.

there is quite a few types of material that will suitably do the job, even small diameter vinyl and teflon tubing will work. part of the issue is those materials get brittle or absorb the oil they carry and have no support once they do and break/rip/blow off quite easily.
the rubber type of hose has to be oil resistant, and even the term "oil resistant" can be hung loosely on many types of rubber hose materials. vacuum hose for example is oil resistant but most vacuum hose isn't nearly as oil resistant as the OEM hoses are, that is why there is vacuum hose and there is "emissions hose". OEM vacuum lines are emissions hose and won't swell up when carrying oil.
the material i use has a teflon inner liner which is resistant to becoming brittle with heat up to 500F, the outer layers protect it further and later on while working around the lines. it's not for everyone, DIY lines can be done for as little as $15 with vinyl tubing and some 2 ear clamps, the only reason my lines are as expensive as they are is because the hose itself cost $30 alone, the name brand stainless 2 ear clamps cost another $10.
i've done cheap repairs on some jobs(FBs for example where my FC/FD/20B lines won't work) with the simple vinyl tubing which gives about the same results as the OEM lines do, most industrial hardware stores carry small diameter vinyl tubing in the plumbing section. in a few years it won't age well though and become brittle and break easily. basically avoid rubber hose, use white transparent vinyl at the very least and it should be small enough in diameter that it requires warming it up slightly to get it on the banjo fittings even before the clamp.
