Hello. This is my first post.

I have a 2006 Ford Ranger 3.0. The fuel pump is bad.
I would like to replace the pump itself and not the entire assembly.
A Motorcraft assembly would be great but I just cant swing that.

I have a spare walbro on the shelf.
With that being said, could I use a Walbro 255lph fuel pump in this truck without any issues?
From what I understand, my truck has a mechanical returnless fuel system with the regulator in the tank.
Would the extra volume overdue the regulator or fuel lines? Any other issues that I'm un aware of?

If not the Walbro, Does anyone have any experience or recommendations on a decent fuel pump that would work well for me?
I see many different brands all with conflicting reviews.. I will be staying away from Spectra pumps. Have personally had bad luck with one in the past.

Any Help or Input is Greatly appreciated.
Thanks

 

Welcome to the forum

Yes, you can do that
The stock pump is 220lph, so not that big a difference

Yes, the Fuel Pressure Regulator(FPR) is on the fuel pump assembly, about half way up

The way it works is the fuel pump pumps the fuel up and out of the gas tank and to the Fuel Filter in the frame rail
The Fuel filter has a 3rd, Return port, that runs back to the gas tank and is connected to the FPR, FPR has a hose that runs to the bottom of the tank to return extra fuel to the tank

So there are two fuel lines at the top of the tank, OUT to filter and IN from filter, they are different size connectors so can't be reversed

I would replace the fuel filter with the new pump

These in-tank FPRs rarely have problems but its also not a replaceable part, not sold separately
Not sure of anyway to test an FPR, but engine would run, you would just get full time Lean codes if it was stuck open, or full time Rich codes if it was stuck closed

 

Awesome. That's great news!

Thanks for the info. Sounds like an interesting system.
I had noticed the 3 lines on the fuel filter when I was trouble shooting.

I'm fairly certain its the pump. Wouldn't start one morning. Seems like it just up and died.. (at just under 75k miles sadly)

Plenty of fuel. No sound from pump. 0psi at the rail. Checked Fuses/relays and bypassed the inertia switched. Verified voltage all the way to the tank.

I'll get the bed off and take a look. Didn't want to mess with it until I had a replacement pump on standby. Thankfully it sounds like I have one.

I will be replacing the strainer and filter.

 

Ford tried putting the in tank FPR directly on the outlet of the pump, then out to the filter
So only one fuel line OUT on the gas tank
They did that for 1998 to 2000 Ranger and other Fords
The problem was the fuel pressure wasn't stable enough at the engine, they were shooting for 60psi, but during acceleration it could drop below 45psi, then with deceleration it would go above 75psi, this drives the Computer crazy when trying to calculate fuel trims, lol, 30psi drift
Pumps can do 80+psi

So they went with the design they had, but added 2nd fuel port on assembly and 3rd port on filter
With the filter being the buffer between the pump and FPR they got the +/- 5psi, at 60psi, the computer could live with
