I am wondering! I am not sure I want to route it in before the filter (Solid square block style) because it will take too long to purge not to mention I would like to keep oil out of the diesel filter. I dont think splicing into the line after the heater and filter would be easy...since its buried under the intake. Looking for suggestions/ideas!

What about relocating the filter off the block and putting on a spin on canister type?


Thanks

Hook it up wherever you can, it will work either way. Most of the purge time is from purging the high pressure lines, the low pressure lines only take a few minutes to purge...

Just keep in mind that if you want to hook up real close to the IP you will need dual lift pumps though unless you mount the pump even closer to the IP...

If you have the model 80 filter, you could take the fuel line going to the IP off of the outlet of the fuel filter and put a vent in there to switch between Diesel and VO. But you better don't feed the IP with unfiltered VO. I would set up two independent supply systems, one for Diesel (already there), one for VO, both complete with their own tanks, lift pumps, filters and return lines.

You could do that, but don't forget the water separator. You can get filters that have the filter and the water separator built into one unit --- as well as two separate filters, one being the water separator, the other being the fuel filter.


Do you need a water separator for VO? Do they even work with VO?

Which are the high pressure lines? So if I hook it up before the diesel lift pump it will work without issue?


I would like to have seperate every for each system...I just dont know how to get into the line straight to the IP

The high pressure lines are the metal lines that come out of the back of the IP and go to the injectors.

The IP is supplied with fuel by a fuel line that goes from the fuel filter to a fitting in the back of the IP, in the middle of the high pressure lines. You probably can't see this because it's hidden under the intake.

What kind of fuel filter do you have, and where is it installed?

Well, one way you could do it (the way I'm considering doing it in the future) is by putting your tank valve right behind the intake so you've only got the little 8-12" line to the IP to purge. This require separate fuel filters and separate lift pumps for each system, however (although that's not a bad idea for reliability anyway).

easy install

put your selector valve near the fire wall, with a 3/8" T before the lift pump. from the selector valve run a length of 3/8" fuel line with the T installed somewhere along the way. run your return line to the T, then continue on to the lift pump. make sure the fuel heater is somewhere before the filter.

running the return just before the lift pump will make your life easy, and also keeps WVO from getting pumped back to the dsl tank when you switch over.

complicated install.

2 systems. filters, pumps, returns.
install selector valve after filters on the firewall behind intake. hardly any purge time. 2 min max.

this is nice if you live in a cold place. you can run both return lines and wvo delivery line together inside a heater hose. that way as the truck warms up the dsl return will help warm up the wvo lines before you switch anything over. i was having some jelling issues this winter. after installing above system, no more problems.
