My name is Malcolm and I am also a newby. With a few months of research and assistance from VegieCars in January this year I changed my Landcruiser HZJ75 to WVO.
After getting so much willing advice from the VO community I feel that possibly I can be of some small help by recounting my experience with poor fuel flow.
Basically the initial set up was a 2 tank system(original tanks),sedimenter, Facet posi-flow aux. pump,home made HE, CAV filter with sight glass (all under tray), lagged fuel and coolant lines to engine bay, Pollack 6 port valve and resistor wires on the injector lines.
From about the second day on I had pathetic fuel flow at the IP. To cut a long story short I spent the next 3 months trying to rectify this by,
increasing fuel line between tank and pump to 5/8"
reducing pump head
fitting larger pump (Gold Flow)
installing a proper counter flow HE and
adding up to 50% diesel (VO is cold filtered to 3u) to no avail.
Two weeks ago I pulled the tank out to see if I could learn something by looking inside. Yes, a completely blocked strainer on the end of the fuel pick up. While the tank was out I had a coolant operated heater and 5/8" fuel pick up fitted.
Needless to say it now runs like a bird, although I have a suspicion that the IP is a little worse for wear as a result of inadequate fuel flow.
