Custom E-Fuel 7.3 Conversion

Ok here's the E-Fuel Conversion System I came up with for my 95' F-350 Crew Cab Long Bed 7.3 Powerstroke. All around the whole system is AN-6 Fuel Lines. I bought a big 30 foot section of AN-6 Stainless Braided fuel line off Amazon For the lines from the tank selector to the valley and the regulator back to the selector. I got 30 feet because I never worked with stainless braided and knew I was going to wast a bunch of it just learning to use the stuff....this was true. I wasted a good 5 feet of the stuff before I found a system that worked good for me. I used NO TAPE while cutting, instead I zip tied a zip tie real tight on the line and cut the line with my dremel. Once I had the line cut I put the fitting on my tailgate and pressed the hose up against the fitting while having my buddy cut the zip tie off at the same time I pressed down. Not the most professional way to do it but it was the best way for me. Not sure what the deal was with the stuff but it worked better with certain fittings, like it worked GREAT with Russel fittings but terrible with Fragola and worked OK with ebay special fittings. Dunno don't care I figured out a way that worked for me so anyone who struggles with the stainless braided try that way and see how it works out for ya!


Anyways so I went with a WIX Filters - 24916 Heavy Duty Fuel Manager Assembly off Amazon for my prefilter. It came with a Standyne 100 base (Even thought not advertised) which paired with the Stanadyne Fuel Manager FM100 Heater Kit I got from thdieselstore.com.


From the prefilter takes me to my pump which is a Bosch 044. While not designed for Diesel I got it for only $90 off an amazon warehouse deal. From what I here they either work great or crap out within the first few miles with diesel so it is a risk worth taking over the 7.3 Superduty pump which was $300+ dollars. To hold the pump I just got a generic Chinese fuel pump holder designed for the Bosch 044 which was like $20 off amazon.


Next is the secondary filter which is a Caterpillar 1R-0750 Advanced High Efficiency Fuel Filter on a NAPA Gold 4770 / WIX 24770 Filter Mounting Base.


As a base for the filters and pump I used a cut out section of frame from a Dodge Ram....had a good time cutting that Dodge frame up When I got the frame back home I cut it up so basically it looked like and L instead of C channel, I then took a piece of angle iron and welded the two together so I could drill holes in the angle Iron and mount it on the inside of my frame. The filters just BARELY sit below the frame...you would only see them from a far.


After I finished up my bracket and got everything situated I then went from the secondary filter to the engine valley to my air compressor 3 way set up. It's just an aluminum pnuematic 3 way coupler I got off Amazon for like $11 with two to the outlets having the AN-6 fittings for the fuel hoses that will feed the back of the heads and then in the 3rd port I got an Edelbrock Fuel Pressure Sensor rated at 30PSI. I got the sensor from JEGS and was the cheapest of the sensors they had available. Basically when fuel pressure drops below 30psi it closes the circuit and in my case I'm going to wire it in with the OEM wiring to trigger the Fuel Light to come on.


I mounted it up by cutting out a custom looking plate out of diamond plate and mounted it to the old fuel bowl holes. To hold the 3 way coupler to the diamond plate I got something out of the plumping isle of Lowe's...I forget what they're called exactly but it was like $1. It's not centered I know but because of how the two lines are routed differently I had to mount it off center to keep the lines equally "stressed" I guess would be the word to use.


I have feeding the heads some Nitrous Outlet 12" press-fitted hoses I got off Summit Racing. Had to call the manufacturer to ensure they will hold up to diesel and they will. They were expensive coming in at $30 a pop (4 in total) but really didn't want to take a chance on doing my own and having it leak fuel all over the down pipe or hot motor and catch fire. They also are A LOT more low profile then if I were to do my own homemade hoses with fittings which is good because I doubt I woulda been able to fit my own homemade lines in the rear anyways. For the rear Lines I also have them wrapped with DEI 010403 0.75" Aluminized Sleeving Heat Sheath - 3' to help them with the heat of the turbo and all being RIGHT THERE. I'm getting a turbo blanket for the turbo, which by the way is a Super Duty converted system with the GTP38R and wrapping the down pipe with some DEI exhaust wrap as well to help keep the heat down.


For the fitting's going into the heads I changed them up a little compared to what came stock. For the passenger rear fitting I used a 45 degree fitting, for driver rear I used a 90 degree fitting, for driver front I used a straight fitting, and for passenger front I used a 90 degree fitting.


Now for the front I had two more of the 12" prefabbed hoses coming out the front of the heads to the Aeromotive 13109 A1000-6 Injected Bypass Regulator I mounted above my HPOP Reservoir. I have a Marshall Instruments LB00100 Liquid Filled Fuel Pressure Gauge coming off the back of the Aeromotive regulator with a 45 and a 90 fitting mated together so the gauge faces somewhat forward instead of me needing a mirror to read the fuel pressure. From the regulator brings me back to my own homemade AN-6 Line all the way back to the tanks selector.































Take note for this whole set up I pretty much robbed bits and pieces from other DIY E-Fuel threads and put my own spin on it. All in all a fun project, not exactly the cheapest DIY E-Fuel conversion but cheap wasn't my goal. I wanted a system that would look as good as it performs. I always loved the look of Stainless Braided lines on the cars at the car shows as a kid so it was cool that I got to use the Stainless Braided stuff and learn how it works. Now with any luck It won't leak once I put the motor back in the truck and test it for real when it's all completely assembled! Let me know what y'all think of the setup!

I actually wound up redoing my original frame mount system. The one in all the pictures above is the system I currently have and the one below is the original system I came up with in my mind....the actual dimensions of my original design didn't materialize until I had it all done and mounted up and HATED IT The 180 fitting on the bottom of the pump stuck down farther then the big filter and just looked haneous and like a road debris could kick up and break it off. SO GLAD I changed it up.
