I'll be using it in my 1994 Mitsi Delica 2.8TD. the fuel pump seals are known dodgy on them though and I have no idea what make of pump it is, so I'm a bit scared of going onto SVO, I think I'd rather go all or nothing and either make myself some BD or not bother.
People keep recommending this guy, but it seems very complicated.
Someone on the Deli forum suggested an easier route and I've planned the attached, with this being the stages to follow:
1) V3, V4 open - pump in WVO.
2) V2, V4 open, heater on - pump it around and heat it to 60ish degrees.
3) V2, V3, V4 open - pump in a mix of methanol and caustic/potassium. Tritration test for quantity.
4) V2, V4 open - pump it around 30 mins.
5) All off and leave to settle for 24 hours.
6) V1 open - drain off crud.
7) V2, V5 open - pump out bio.
After V5 I'll need some inline filters down to 1 micron as well, then it should be ready to use in ANY diesel as a straight replacement!! Average cost about 20p per litre!!
But I'm still scared, ideally I wanted some more opinions from people who've tried it, see what mixes they've tried and whether they've washed it or done some shake tests to check for glycerol etc.
