Re: Pre Heating WVO before injector pump
Mark, I would have thought that the Franz would have the biggest volume of fuel. If you have one of the Heltons it should only have a tiny amount of fuel in it compared with a fuel filter or even worse the Franz. Even a 30 plate FPHE would not contain as much oil as a Franz.

Yeah it's probably not necessary, but I'd rather err on the side of caution. But I've just set up my 1HDT on SVO and the Frantz was causing a bit of a problem. When I got up around 100kmh iut was starting to suffer fuel starvation issues. I wasn't surprised because when I was installing it I was concerned about the narrowness of the internal diametrs of it's fittings - about 4mm. I naver had a proiblem with them when running on bio, but SVO is of course thicker, even when hot.
But I fixed the problem by reaming them out and putting 1/4" BSP fittings in, with a much larger diameter. Problem solved, but my system now has a huge dead volume in it. Once the fuel gets into the engine bay it goes through the heat exchanger, then the Frantz, then the factory filter. So when I'm switching back to dino before I turn it off it takes 7 or 8 km driving to purge the system
