I am putting a fuel cell in the back of a 89 4Runner with a 22re. It is a aluminum RCI cell. Any suggestions on a external fuel pump? As a back up plan, I got one that is tall enough (fingers crossed) to fit stock fuel pump housing with only minor mods (hopefully).

I use an external pump, bosh 040. If your running any power you will need a 044 but the 040 is great is a stock replacement.

um, sorry but the bosch 040 is an in tank pump. The bosch 044 is an external pump. The only difference between the two is the fact that the 040 runs at 94 PSI and the 044 runs at 72.5 PSI. Operating pressure has nothing to do with how much horsepower you are running. So this really is not a performance difference. Both flow the same amount of fuel 80GPH. This is what determines how much HP that a fuel pump can supply. Since both pumps can supply 80 GPH they can both supply the same amount of HP.

edit, some site I've been looking at list the 040 and 044 as being 300LPH. Other list the 040 as being 235LPH. so depends on which site you get the pump on but even if this were the case the 040 can still supply 600HP!!!. Unless you running a bangin supercharged 3.4 then the 040 will work in almost any case.

I apologise, I have the lower flow rate external...I thought it was 044 but Im obviously mistaken.

yours could be either the 909 39 GPH (148 LPH), 910 34 GPH (130 LPH), or the 979 43.5 GPH (165 LPH). then.

I have a Bosch 044, the thing's bigger than a beer can! It's a little bit of an overkill pump for a 22R-E. I believe bosch makes a smaller inline pump though. Go with that.

I would highly recommend staying away from Walbro fuel pumps. They do make an in-line version of their classic Walbro 255, but their pumps are very noisy, flow next to nothing at pressure (not that you non-turbo guys would ever care), and the failure rate of them is through the roof compared to other brands. There's a reason that brands like Denso, and Bosch are used in OEM applications, and are also more money, and why Walbros aren't.

also look into the Carters.
