Superchiem's 3.0 to 3.4 swap

I cut the weird shape hole for the pressure sensor. It may not be perfect, but its a tight fit.

If you look at how the pressure sensor it is mounted to the 5vz fuel pump. You have to take the pump out to get to it. I didn't use the 5vz pump, but kept the old pump. So I had to have bolts come out to the tank so I can secure the pressure sensor.

I sealed the tank around where we soldiered.

Then paint:

I'll throw one more coat today and rinse the tank out tomorrow and mount her up.

Thanks guys!

Got the tank ready to mount up. Had to plug a breather port that goes to the filler neck. We won't be using that anymore.

This goes to the smaller tube on the filler neck. We are still using the filler neck side. It will go to the charcoal canister.

I needed to add 2 lines to the filler neck because thats how the 2002 4runner was set up.

Visualize:

And Attack!:

I used 1/8th npt to a 90 degree 1/4" barb. The fuel hoses used on the tank are mostly 1/4".

Here is the top of the tank.

I forgot to mount the large black float. I had pulled to tank off and put the float in. I found out that it touches, but barely. I'm probably going to add a few washers or something to bring the tank down 1/8".

Ah another day with no work. Toyota sales are down I guess. So we have been slow.

Anywho, added 1/4" line to the filler neck. A bit of advice when adding the 90 degree brass fittings. Make sure you put them anywhere above 3 and 9 o'clock. That way when you pour gas it doesn't get into those lines. I figure I should copy how the stock 2002 4runner filler neck was.

One goes to a return line on the tank.

The other to the large float thing.

You can see the float back there, with about 1 inch of gap. I had to loosen the tank to get my hands in there. The float actually sits up against the body of the rv. I have to make some spacers for that.
