The following is a copy of a post I did on another forum last year.
Now that winter is here I decided to park my truck in the shop to give me something to do in the evenings. I decided there was three things on my to do list. IDM mod, DIY stage Is, and to convert from mechanical to an electrical fuel system. I know that you can buy kits to do this but part of the fun is trying to gather together all the parts you need. Luckily others have done this before so I didn't have to try and figure out what regulator and filters would work. Here is the list of parts I used and the costs.
Prefilter and base - Stanadyne 33640 (thedieselstore.com) $74.64
Secondary Filter Base - (WIX): 24770 (Fleetfilter.com) $26.00
Secondary Filter - (WIX) 33528 (Fleetfilter.com) $9.00
Fuel Pump - (ebay.com) $114
Fuel Lines - Stainless steel 3/8" under turbo (local) $100
Oil pressure switch - Holley 12-810 (amazon.com) $28.00
Fuel pressure switch - (local) $25.00
Fuel regulator - Aeromotive 13109 (ebay.com) $133
Fuel hose - Parker (international dealer) $5.00
Stainless hose clamps - (home depot) $7.00
Fuel pressure guage - (harbor freight) $5.00
Brass three way connector - (harbor freight) $4.00
Fittings misc brass - (harbor freight) $13.00
Fittings - Parker (local) $37.33
Wire - (local) $5.00
Fuel pump bracket - (wrecking yard) $5.00
Misc stuff - (local) $9.00
Total - $600
The first thing I did was remove the stock filter housing and pump. The only thing I left was the fuel lines coming into the valley from the tanks.
I went to a transmission shop and had some custom made 3/8" stainless steel fuel lines to go under the turbo. These attached to the back of the head and came together with a brass three way air connector. I bent the stock lines by hand into the right positions being careful not to kink them. I did not need to cut them to make them fit.
I fabbed a bracket out of stainless steel to mount the pressure regulator to the bracket on top of the HPOP reservoir. I reused the existing flex fuel lines coming from the front of the heads into the fuel regulator.
The wire for the fuel filter restriction was plugged into the fuel pressure sensor to light the dash light if fuel pressure drops below 20lbs.
I went to the wrecking yard and got a fuse box from an F150 so that I could add another relay and fuse to my fuse box. I added the relay in the upper left corner and the large size 30amp fuse furthest to the right. All wiring was run in existing looms where possible. I wanted this whole setup to look as factory as possible.
