GX550 fuel tank in a Land Cruiser

[Winchester44]

Would love to see if someone comes up with aftermarket exhaust. It seems huge vs. overseas diesels. I'm not sure if its the muffler or muffler + catalytic converter, but man that thing is huge. The 300 series has plenty of room for driveshaft, muffler and TWO fuel tanks between the rails. Check out this photo of a 90 L replacement sub (aux) tank for the 300 next to the factory 30L sub tank. With replacement tanks they can push 270 L of fuel capacity. 71 GALLONS!

Very interesting! Do you have a take yet on those claiming that Toyota's non-hybrid gasoline tanks are fundamentally different than hybrid gasoline tanks and therefore completely non reverse compatible? They point to the warning about the tank being "pressurized" in the manual. However I suspect this is just a function of the environmental vapor recovery system common in all modern fuel tanks. Others claiming the continuous on/off of the ICE engine requires different fuel supply pumps. However, you seem to have identified that the the fuel pump is actually the same.

So ..... Toyota didn't invent a new "type" tank or fuel pump for the LC, of course the tank is a different shape than others because it's a new frame/body and the available space is different than other models.

A fuel injected engine is a fuel injected engine, whether port injected, direct injected or both, nothing special about that. When the ECU calls for fuel, it turns on the fuel pump and turns it off when it doesn't. How often this happens has nothing to do with fuel tank or fuel pump but how often residue fuel is returned to the tank (diesel is a different story).

If you read the warning in the manual about being "pressurized" , you are correct about the EVAP system, just like every other fuel injected vehicle. Most probably put in there along with many other warnings so that Toyota wouldn't be liable for the idiots out there waiting to sue because they inhaled gas vapor.

The fuel pump for the LC has the same part number as the fuel pump for the GX.

So the limitations as I see them are; the physical space available in the LC vs the GX and the physical location of the fuel pump, relative to the frame, on the LC vs the GX and is why the GX fuel lines were ordered (hopefully won't be needed).

Can't see where I'll ever need 71 gals between fill ups.....LOL but I might look at that 10 aux tank someone posted about.
