95 F350 fuel routing diagram?

[techno550]

Anyone know where I can find a diagram of the fuel flow/lines/filters/tank selector valves/etc? I'd like to know fuel component location and fuel routing.

Thanks

not sure on a diagram but it runs up the inside of the drivers side frame rail, pump is on the back of the engine towards top

Thanks. I guess the fuel filter would be behind that / under the cab somewhere, and before that would be the selector valve?

fuel filter is in the bowl on top of the motor, fpr is there as well, that black plastic peice on the top of your motor, unscrew it, that is your filter, drain a little out before you replace by sliding the yellow button on the side of the fuel bowl, otherwise it will just run over and fuel on top of the motor, btw it drains down the front side of the block

your selector valve is on the frame rail infront of the front tank

lines from tanks to selector valve
lines from selector valve to motor
fuel goes to the pump, out to the fuel bowl, back to the pump, to the back of the heads, returns to the regulator on the side of the fuel bowl from the front of the heads, then through the return line back to the tank you have selected

that sounds like alot

Thanks!
Still very new to this truck (less than a week) and learning the ropes.
I see a lot going to electric pumps from the mechanical. Is there a problem with these mechanical pumps in terms of reliability? Or is there some other reason for the change?

I also have a 1987 300D, and the mechanical pump on that is indestructible.

If that little bowl is the only fuel filter, I suppose I can see why/how adding another could be helpful.

My intentions are for WVO at some point, and I'll need a good understanding of the fuel system for that to work properly.

Converting to electric fuel gives you more consistent fuel pressure for better performance. These trucks like around 65psi of fuel pressure, with the mechanical pump it can vary widely. Plus the mechanical pump is a bit of a pain to swap out.

we have a whole section dedicated to that info on wvo, and alot are swapping to e fuel because it will give it better throttle response, if you plan on larger upgrades like turbo and injectors then e fuel is the way to go, it also increases fuel psi for those upgrades, nothing wrong with the mechanical fuel pump, just obsolete when it comes to larger go fast goodies
