[ridiculously_necessary]

First I would like to thank vegginpsd and tubular031 for their help in building this schematic. I got a great parts list from tubular031 and vegginpsd explained how to get rid of the fuel bowl and reduce the number of parts from my first version. I will likely revise this with comments, and again when I get around to the install. Also a big thanks to everyone else on the forum as well as DFA. I learned in this section how the PSD fuel system works.

This is for my 95 OBS (94.5 to 97). I will be removing the mechanical fuel pump and fuel bowl. This is sort of an arial view, with tanks and such obviously moved for readability.

Here is the fuel system:

Here is the system with color coded coolant setup:

Here is a link to Tubular031's setup. he needs a plug as well since he helped with this. there are pics too: http://www.powerstroke.org/forum/bi...plements/89570-01-f350-7-3-psd-converted.html

I would like to add that this will also be nearly identical on a 99-03 PSD 7.3:thumb:

for those who are not aware, he is referring to the fact that a 99-03 has an electric fuel pump stock, no mechanical one to remove. Just the fuel bowl, if you so choose. iirc the fuel enters the front of one head and the back of another on a 99-03, so adjust accordingly.

this is a great setup.

please document your install with pics and add it to this thread.

great info for someone who is looking to convert a 7.3L.

I will be for sure!!
I am going to start my pricing probably tomorrow ( very very general pricing on parts.) i will definitely need the expertise on here for that.

As far as the lines and that kinda thing it'll be fairly cheap as i have most of that from other projects...

looking at the artic fox tank heater how does it work?

There are better tank heaters out there but basically the AF has a coolant tube surounding the fuel pickup tube that extends down from the top of the tank to the bottom. They work ok for mildly cold climates but way up north they will give you problems if your oil has alot of FFA in it from animal fats or if you use PH oils.

im in Al, so not much anything under 30* here...and when it does it's only for a few days.

Since this is a sticky, Ill post mine here too.

About time you post up a good picture of your setup oke:

That was for matt we started talking about this maybe 2 or 3 months ago

glad he got it all figured out

MSD 2225 enough pressure ?

I am collecting parts for my 1996 F-250 and when I oredered the MSD 2225 from summit , I noticed it is rated at 40 psi max . Is it working OK on your system , or do I need a higher pressure pump ? Thanks .

As a stand alone lift pump, it is not going to cut it. 40# of fuel pressure is quite a bit short of what your truck needs. That is a toy by comparison to what most of us use. Try FASS HPFP (recomended) or the Air dog.

That pump might limp you by on D2 but it wont handle VO very well or very long. :thumb:

I have a FASS RPFA 1004 for the WVO side along with a vormax . The schematic DIY build v1.13 shows the MSD 2225 on the D2 side . That was the reason for my question . Apparently I should upgrade that to another FASS or a Raptor or something at least 60 psi ? Any other suggestions are appreciated .

A stock Super Duty pump would work too. Ebay under $75 IIRC. Inline regulated......

 

[ridiculously_necessary]

you are correct. i discovered this a few weeks back and have not corrected the diagram yet. i recieved some bad info from a supplier on the MSD2225. thanks for reminding me.

i found an SD pump for $70 on ebay, i believe its a generic Airtex pump - not sure. here is the place, global automotive...

Could you post your parts listings for the 4 way fuel manifold and check valves? I think I'm going to do an ITP regulated return and just feed it into a 3-way to control returns. All I need help with is the CV's and the 4 way manifold.

 

[vegginpsd]

You just need to go into two corners with the feed lines. Two tee's, making two supply and two feeds. Place check valves on the VO and D2 supplying the double tees.

*Just a reminder*------------>
A regulated return will crush your vo temps unless you have a large FPHE (minimum 20 plate).

Remember its best to return fuel on the VO side in a loop configuration to conserve heat.
