The install is going good.
I have got the tank in place, the temp gauge is almost in place.
I mounted the 3rd valve. And I decided that I need to somehow label the valves.

I found a very nice filter and head from TruckPro.
It think it is a Baldwin fb1311. They also sell these GIGANTIC 10 micron filters for it for less than $10.00 a pop. I think it is designed for a Cat.

I still haven't gotten around to taking the pics but I have a few from the beginning stages that I will post soon.

I think that tomorrow or Monday will be the day that I finish it. We shall see.

OK. I have got her runnin on VO but not 100% correct yet.
Here are the pics. I do not know how to post hem directly onto the website so I have them on photobucket. Here is the link.
http://gs99.photobucket.com/groups/l284/E5EB12TY9W/

I am using a steel mesh screen for the pickup. By the way if anyone likes it them I can send one of my extras to you for $35 delivered.

Of course as you can imagine I am having problems.
I have a draw up of my fuel system right here on this link.
http://gs99.photobucket.com/groups/l284 ... can005.jpg

My diesel fuel is going into my VO filter.
I t'ed in the steel line in b/w the filter and the IP and that is where the VO line enters in.

So basically I think that I am running everything through one filter. I am very thankful that it is not 20 degrees out like last week b/c I would be in a lot of trouble. I also T'd for the return down low under my feet b/c it was much easier to get to than behind the Stock fuel filter. (by the way does anyone know how to change that beast) I looked in the manual and did what it said but I could not get it to spin.

Did I T in the wrong place??
Any help with this would be greatly appreicated

Ok Guy's,
Tell me if you think this makes any sense at all..
When I start up on diesel it is running through the diesel filter and then the pressure is backing up into the T that I cut and then into the VO filter (backwards).
It appears as through this is happeneing but I am not totally sure. Could this be happening?

Also, where I cut and plugged the injector drain manifold I cannot seem to keep the fuel injection hose from leaking. I started off with 1/4" fuel hose and now I have 1/4" fuel injection hose that clamped on w/ a bolt in the other side. It is leaking some where the clamp is over the steel hose. I just clamped a second one on there now. We will see how that does.

Your diagram is very wrong for returns, see my diagram. The returns shouldn't go to the stock filter, or into the VO loop. You don't show the injector drain line so its hard to tell what you did with that. And you don't show the lift pump so its hard to tell if thats wrong too.

I think thats a 3/16 line.
You don't plug the injector drain manifold, thats likely your problem. See my diagram or my conversion thread:
"you have to cut the existing injector drain manifold (small line) going into the top of the stock fuel filter and cap that line, and tee the injector drain line into the IP return line, so the small amount of VO in there gets sent back to the proper tank. "

Wow.
That is not good.
Do you think that is what is building up the pressure in b/w the VO filter and the T that goes into the IP when I run D@??

Cant tell without a proper diagram of what you did, but I can say that diagram is very wrong.

Yeah I have made more mistakes on this project than I can count on my hands and yours.
I am very thankfull that the weather has been unseasonably warm lately b/c I would probably have been stranded several times if it weren't.
I hooked up the T from the inj drain manifold and I think that has releived some of the pressure.
I definitely need to hook up my valves in the same way as your Sun. I see one major difference and I will address that tomorrow.

Thanks.

Has anyone here ever changed out a thermostat for a Dodge 2500 2nd Gen.
I have the type of thermostat that does not hold a constant temp and it never really reads in the middle (190).
I want to put in the hottest thermostat I can find. Does anyone have any suggestions for this?? (where to get it and ease of changing out)

Thanks

I found this one on ebay,

But I was very suprised at how cheap it is.
Is this one any good and will it be constant??

I used a stock NAPA t-stat. When warming up, it jumps from 140-190 as it first opens and closes and the large amount of coolant in the radiator gets in the flow, then when warmed up it stays steady at about 190. This is how any willl work when properly operating. It was cheaper than that one (counting shipping.)

I called up the Dodge dealership today and they are wanting $45 plus tax for a thermostat.
I think I will go with the one you suggest from NAPA.
It is a 180 degree. I sure hope it can stay at that temp or close to it.
It is tough to get the oil to 160 if the coolant doesn't get much over 140..

I installed the t-stat and it is working much better now. Staying warmer longer and my veg oil is getting 5-10 degrees hotter
I also put a piece of cardboard in front of the AC condenser and in b/w the grille. I heard about it keeping the temp up and it too is getting the temp up about 10 degrees.

I ordered a vegtherm mega and I should be getting it next week. I think that this will allow for a quicker switch over.

We'll see.
