Removing fuel pump

Can the fuel pump be totally removed through the under seat access without dropping the tank? If you have replaced your fuel pump and have pics, please post those also.

Re: Removing fuel pump

Nope.. It's easier to disconnect the plug trough the access under the seat but the seat access port is way too small to remove the pump. Remove as much fuel as possible then drop the tank. Fuel weight is the most difficult part about tank removal though, it's a pretty easy job if the tank is empty. I was hard headed and tried leaving about quarter of a tank in there and had to siphon it out. The fuel lines are "snap" together style no wrenching involved. I have an 07 that's been in Ohio all of it's life so the plastic tank skid bolts were rusted so I left them in place and pulled the tank straps.

Thanks for the tips. Did you inspect your old fuel pump? Did it have a lot of dirt, sand, etc. inside? How did the filter look?

Re: Removing fuel pump

I was having no problems with it. I supercharged mine at 50k mi, and did the urd fuel pump and filter upgrade. The sock filter did have some build up but only directly across from the intake tube where the fuel would most directly be sucked into the pump. The rest of the sock was clean. My FJ doesn't see a lot of off roading and zero sand. I live in the country and it does see dusty roads andsome mud.

Re: Removing fuel pump

Toyota dropped the ball on this one. Should be able to access it with out dropping it. But you cant. next pump change I am cutting a hole in the floor & making a plate. I bought a Denso Pump from Advance auto for 200$ best deal I could find.

Re: Removing fuel pump

You can remove the seat and enlarge the access hole to the fuel pump area....which will let you remove it that way. It involves cutting sheet metal. Otherwise, you gotta drop the tank. :-(

Re: Removing fuel pump

Honestly I wouldn't cut to enlarge the floor opening. Once the tank is empty dropping it is no big deal.
