I have a 1988 F-250 4x4 with 7.3L. For a couple reasons (1 of which is I destroyed the fuel heater sensor getting it off) I'm going to remove my mechanical fuel pump and stock filter system and replace it with the system below. I can't see spending $120 for the new sensor and then still have it leak. Which is a distinct possibility from what I've read.
After the fuel selector switch I will install a fuel filter such as a Napa 3270 or equivalent. After that I'll use an electric fuel pump. After some extensive research I'm going to use a Facet
40107 electric fuel pump. Specs are 7-10 psi, 38 gph, 12" max dry lift. It's only 18 oz and 3" and about $40 from this online store
. I thought about the dura-lift pumps but they are over 2 times as much and I'm going to use it back near the fuel tank anyway. I'll wire the Facet so it will only run when the ignition key is on.
I'll use the stock fuel line up to the engine compartment. I'll remove the mechanical pump and block it with the big block chevy fuel pump cover. I'll use fuel injection hose from there to a Racor 445R (hoping to mount it with an adapter on the old stock fuel filter mounting bracket). The Racor will have the fuel heating element and water detection probe. Then I'll use fuel injection hose to the old line to the injection pump.
A couple of questions. I'm assuming I can block off the old return line that used to go to the stock filter. That way excess fuel will just run back to the tank. I'm also assuming I can use the old wires to connect the fuel heater and water detection probe. Anything else that I might have missed? I'm still in the planning stages so any changes/additions are still possible.
Thanks to those who have posted questions/answers about these issues. I've done quite a bit of research and most of the answers I came up with came from various diesel forums. This one included.
