Hey all. Ive got a question about swapping fuel system parts. Ive got access to a 2000 ford f350 7.3 that had a cab fire and pretty much ruined the truck. I was wondering if I could take some of the fuel system parts over to my 97 f250 7.3. I was doing a quick look over and it doesnt look that bad. I was thinking of swapping the fuel bowl assy and fuel pump over to my truck. Whats the feasibility of this or is it even worth the effort. Im goin to change my fuel pump anyhow, so i figured while i was that far into it go ahead and do it. The stuff is free, and other than a little wiring looks to be pretty straight forward and bolt up operation. Again i said looks lol, but is it worth the time to take the pump and filter housing off the 2000 and put it on my 97. Thanks,
Wes

In order to use the 2000 filter bowl you will have to put the hpop resevoir off the truck on yours too. The fuel bowl isn't worth the trouble really. If you already have the pump to use, you can buy a pressure regulator and a fleetgaurd or something else of your choosing filter head and such with screw on fuel filters to use on the system. In short, tak your fuel bowl out and block the hole in the block, and build your own system using the sd pump. Look over the hpop pump too, if it is a 17* pump it is also an upgrade for our trucks. If I remember right though a 2000 may have the same as ours, a 15* or a 17*, the only real good way to tell is pull the back cover off the new pump, held on wiht a snap ring. If it has a bushing it is a 17*, if it has a bearing it is a 15*.

ok so if i dont use the filter bowl off the 00 i could use mine? is there a particular need to delete my filter bowl. ive taken it off and cleaned it out, removed the fuel heater element, and replaced all the hoses and all the orings in the housing and fuel pressure regulator. i was thinking about taking the stock fuel pump and cutting the inlet and outlet off the pump and welding them together so i can utilize the stock banjo fitting and outlet so there would be very little plumbing other than cutting into the lines at the tank to insert the super duty pump. I'll also check out the hpop as well being since thats my next up grade to try to find the stumble ive got under boost

Our bowl will not take the pressure I am in the process of doing the same thing you will need a filter and head to put down by the new pump and delete the stock bowl.
I am going with a set up like swamps have.
Just 1 filter instead of two like some others use. So all I had t get was.

1 electric pump (eBay)
Filter and head (Napa) 3407 & 4770
Regulator (e-bay) fittings 10AN orb -4AN x2 6ANorb- 90deg elbow -5/16 barb
Fittings for head 1/2 pipe -5/16 nipple X2 (local hardware)
Fittings for the pump 10mm - 5/16 barbs (hydraulic shop)
2 ft 5/16 fuel line (Napa)
1 ft 3/8 fuel line (Napa)
7 5/16 clamps (Napa)
2 3/8 clamps (Napa)
2x2 angles to mount filter (welding shop)
Adaptor fitting to keep banjo fitting (hydraulic shop)
Relay

What regulator did you use? What pressure is the regulator set at?

Ok. Well im not doubting anything anybody says, but im just curious. If i use the stock 00 7.3 pump and they have a filter housing why cant i use mine? I work at a Carquest auto parts store and have been researching pressure on both pumps. Ive talked to a couple of diesel mechanics and they said both trucks operate on the same pressure. Im just curious. I know every aftermarket fuel systems come with screw on filters, but my thinking would be a cast housing would stand pressure better than screw on filters. Again like i said im just curious.

The 94-97 year trucks used a two-stage mechanical fuel pump with the filter located between the two stages. Because of that, the filter housing is designed with 3-5psi pressure in mind. Other than blowing the lid off, I could envision that it might leak at the fuel-bowl heater connection or pass too much fuel out through the air-bleed orifice if you run it at 50psi.

Additionally, the fuel pressure regulator system is set up differently on the SD trucks. The bypass flow from the regulator goes from the filter back to the tank, whereas in the '94-'97 years the flow path goes:
filter -> second pump stage -> heads -> regulator -> tank.

In short, you probably could use the existing filter assembly, but with all the jury-rigging and re-engineering it would take to make it work you would likely be time and money ahead just to go with a high-quality spin-on filter.
