about 10 minutes to pull the bed..make sure u have about 4 of your buddies to help lift the bed off. From removal of pump to install back into tank about 30-45 minutes. Wire cutters/strippers, flat head screw driver, 2 butt connectors and some shrink wrap

Sticky!!

I remember reading about using hose that is not specially rated for fuel will swell up and fail after a week or two.... The hose that came with my walbro from magancharger was plastic, not the typical heater hose type stuff.

the line that came with it says high pressure efi hose on it so i hope it works :lol:

The problem is most "fuel hose" is rated for the inside only. In the tank, the outside of the hose is exposed to fuel as well.

Fuel hose

ah, this is where I just read it, post 17, Solution,,,Walbro checkvalve prime???? - PerformanceTrucks.net Forums

true..i guess only time will tell

mine is in tank like that with the same line for 2yrs now works fine

you NEED submersible hose. Napa sells it...it is 27 a foot. TOTALLY worth it. That hose will be gone in a month and will probably clog the pump. How long is the hose? I have access to pieces 7 inches for free....if it's longer then that, you'll have to go to napa


needs to be sae30r9 approved. Do a search on here, the part number for nasa will come up.

took me few days searching here and other sites to actually find a walbro write up on a 04+ truck with returnless still. this should be sticked somewhere.

i agree!

Very good write up, I might end up having to do this to my truck!

2 questions.
1. Did you use the pre filter, if so how, if not did you use an inline filter?
2. How did you hold the pump up off the bottom of the bucket?
