Solvent to Biomass Ratio

I get em from various sources, the hfs cheapos arent bad. I had custom made hoses from someplace like discount hose- arrived bad but they replaced. Last run i had some hose leaking I have no idea what source. i got hoses from the classifieds here, hfs, bvv, 2 custom sites. I got hoses and valves out my ass on my system.
