I bought a little under a gallon jug of gso from cash n carry (restaurant supply store) and one fast cap was able to filter enough vitamin to where i used almst the whole jug before chucking the filter w the exception ob tren ace using its own fastcap and destroying it after filtering 1000ml thru it clogd the sob.....listen jst order the fastcap and then buy urself the self brake bleed kit from auto store it comes w the 2hoses u will need fat cap sits on top on sterile media or glass flask of choice both hoses plug into the 2 diff ports on top on fast cap one hose then goes into unfilterd vita oil and other hose connects to vacuum pump (gun) squeeze trigger until u get psi to about 12 and it will do the rest on its own when its done put ur fastcap in a ziplock baggie or whatnot to store til next use....at least this is what workd for me i promise u wont even worry about the 25$ u spnt n wont want another filter after
