What did I do with my 2005 Ranger today? I changed to fuel pump.

I started to notice my truck wasn't starting as quickly as it should, and determined that it was the check valve in the fuel system leaking. It became progressively worse until I had to cycle the ignition key 3 times to build up enough pressure for the engine to start. Each time the key is turned to on, the pump runs for 3 seconds to pressurize the system, only my fuel system wasn't holding any fuel in the lines.... requiring the pump to run more to obtain enough fuel to start the truck.

This check valve is located on the gas tank and is part of the fuel pump assembly... Access to the pump is through the top of the gas tank... which is under the pickup bed. I had two choices to gain access to the pump:
  1. Lower the fuel tank from the truck
  2. or remove the pickup bed
I went with option 2 as I have long owned a 2 post lift which should make easy work lifting the bed. I started work on the project this morning. I began by removing 6 bed bolts which held the bed to the truck frame. They are long bolts but came out relatively easily considering that the truck is 18 years old. A few were tough but all eventually came out. I am going to be cleaning them up prior to reinstalling them. Here is a couple of them.

Before going further I decided to protect the cab and the bed. I used moving blankets and painters tap to secure the blankets where there was a possibility of the bed damaging the cab.

Once this was accomplished I attached a 400lb ratchet strap to each of the four tie down points in the bed looping them over the post. This should allow me to raise and lower the bed with precision.

Plenty enough room to access and remove the pump.

Here is the target of all this effort. Going to cleanup the area, then replace the pump assembly. Don't want to contaminate the fuel or tank.

I removed the 4 fuels lines from the original pump assembly. Then unplugged the cable. The red tab has to be pulled out to release the cable. The fuel lines all required depressing the colored tab on the line cap.

Here is the new pump. It cost $300! And the original pump with 18 years and 165K miles on it. The days of $20 mechanical fuel pumps are gone!

The tool I purchased to remove the pump seating ring did not fit my truck... and will be returned for a refund. I ended up using a large flat screwdriver and 3lb hammer to break the ring loose. I then placed the new pump in the tank and reinstalled the pump ring, locking it in place with the same screw driver and hammer. Worked like a charm.

Once the pump was in place, I started the truck and checked for leaks and other issues. All was fine. Truck started and ran fine.

The last thing to do was to lower the truck bed and reattach it to the truck frame, then install the tailgate. I lowered the bed down until I was 1" off the frame. I then inserted the bolts to guide the bed into perfect position. Once the bed was in place I tightened the 6 bolts, and removed the protective moving blankets. We then drove the truck to our nearest gas station and filled the tank.

This was not as difficult a job as I hand anticipated. The lift made easy work of the task. This was also the first test of the lift since I installed the new hydraulic lines earlier this year. It performed wonderfully.

Tomorrow I will pressure wash the truck bed floor and reinstall the rubber mat.

Next up? Installing the PPE deep pan on the 2020 Ranger

Way back when I replaced the engine with a Jasper rebuilt, I didn't clean or replace the injectors. I really should have as I noticed lower fuel mileage and am uneven exhaust note. So just before changing the fuel pump (with the tank at 1/3 full) I tried the ATS505 fuel treatment in an attempt to clean the injectors. I had been using Royal Purple's Fuel Treatment product with only modest success. Things would clear up for a month, then the roughness would come back. Anyway, I followed the instructions, and then ran the tank near empty in preparation for the pump replacement.

I just completed my first full tank of gas, and my gas mileage has improved significantly, and the exhaust note is even. Prior to the fuel treatment and fuel pump replacement I averaged about 270 miles per tank. This first tank came back at 300 miles with just under an 1/8th of a tank left. The yellow low fuel warning light wasn't even on. Second tankful went 320 miles!

This is right about where the fuel mileage was when I first purchased the truck years ago. 19.8 mpg isn't too bad for a 2005 4x4 Ranger! This was combined city / highway (at 75mph) with AC on. I didn't baby the truck at all.

It is too early to announce success, but I am hopeful, as this is the first time I have seen 300 miles per tank in years. I probably could have gotten 325 if I had run it to the warning light.

8,000 miles on the rebuilt 2005 Ranger.
