4 PULL WIRE HOLDERS (3 PUSH IN PLASTIC) FROM FRAME HOLDING WIRING HARNESS TO GIVE YOU MORE SLACK ON WIRES WHEN LOWERING TANK (LIFT WITH SCREWDRIVER THEN PRY OUT WITH NEEDLENOSE)
5 REMOVE HOSE CLAMP ON TANK HOLDING FILLER RUBBER TUBE (HAVING THE TANK ON THE JACK WITH STRAPS OFF YOU CAN MOVE IT A BIT TO THE RIGHT TO GIVE YOU A BIT MORE ACCESS, ALSO REMOVE FILLER VENT CLAMP , CUT WITH DYKES AND USE 3/8 HOSE CLAMP TO REPLACE.(REMOVE THE GAS CAP)
*note* THIS WILL BE THE HARDEST PART OF THE REMOVE / REPLACE , YOU DON’T HAVE MUCH ROOM AND YOU CANNOT LOWER THE TANK THAT MUCH OR YOU CAN SNAP THE NIPPLE OFF OF THE FUEL TANK

NOTES
• ALL F-150 FUEL PUMP ASSEMBELYS (PUMP AND SENDER HANGER) ARE SOLD BY WHEELBASE , AND THIS IS IMPORTANT BECAUSE OF LENGTH AND DEPTH OF THE TANKS ON DIFFERENT MODELS.
• MINE WAS A 2004 F-150 5.4 4X2 SUPERCREW 138.4” WHEELBASE MY PUMP OPTIONS WERE , MOTORCRAFT P/N PFS208 , DELPHI #FG0846 ,CARTER P76343M,DENSO #953-4037, AIRTEK E2533M
• SOME GOOD INFO AND VIDEOS ON CLIP REMOVAL AND REPLACEMENT CAN BE FOUND HERE www.fuelpumpu.com/vehicle-search.aspx#
• 3 HOURS START TO FINISH , GET THE CLIPS BEFORE YOU START 5/16 AND 3/8 JUST IN CASE (ALWAYS CAN RETURN TO FORD IF UNOPENED). IF YOU BREAK THE YELLOW ONE ,USE THE ONE ON THE EVAP CANISTER(NEAR THE SPARE TIRE) TEMPORAILY AND REPLACE IT LATER , ATTACH THE HOSE WITH TAPE SO NO CODES , AND YOU CAN ALWAYS REPLACE IT LATER EASILY .
• MAKE SURE YOUR FUEL PUMP MODULE IS GOOD (ABOVE SPARE TIRE) USE A TEST LIGHT TO MAKE SURE YOU HAVE POWER (KEY ON NO START) TO THE WHITE WIRE , JUMPER ACROSS THE WHITE TO BLACK/PINK (POSITIVE) AND BLACK/YELLOW TO BROWN WHITE (NEGATIVE) ( OPPOSITE ENDS OF THE FP MODULE PLUG) TO SEE IF THE PUMP RUNS , IF IT DOES BAD MODULE !!
• I AM A BACKYARD MECHANIC AND DID THIS IN MY DRIVEWAY , IF I POSTED A PROCEDURE WRONG , SORRY JUST TRYING TO HELP !( THE WIRES ON MY PUMP INSIDE THE TANK WERE ACTUALLY MELTED OFF OF THE PUMP CONNECTORS ON MINE , CAUSED BY LETTING THE TANK GO EMPTY TOO MANY TIMES PUMP NOT SUBMERGED RUNS HOT , AND 130K OF MILES)

 

I think this is a first. A new members first post is a Tech Article. Good write up!

 

I copied it over and indexed it in our Articles and How To section.

 

Very good first post indeed!

 

i just joined the forum so I could respond to this post.

Thank You !

I'm in Chattanooga TN and NO ONE seemed to know what clips I was talking about. With the part numbers they still didn't stock them!!!! 3 dealers and multiple auto parts stores. Finally called a dealer in Georgia who not only had them (right at the window) but was shocked when I told him my local dealers seemed confused.

Everything went fairly smooth once I had the new clips. If I had to do over I would remove the bed.

Mine is a 2004 Extra Cab Long Bed (145wb) with 5.4 sneeking up on 300k. Its fairly new to me and is getting 17-18mpg.

 

Well, stick around and join in the discussions.

 

Glad it helped !! Bed removal wasn't a option for me , no amount of beer could get my friends over to help !!!

 

Haven't had the energy to check it out, but I've got 2 issues.
1.Harder to start, it takes a couple turns of the key(used to fire almost instantly).
2.Guage is not accurate.

Before I tear this thing apart again, can someone point me in the right direction....
