So you just want to run a single EFI pump in-tank?

 

The most common solution to every carb to EFI conversion I've read about is the VL in-tank lift pump + VL external EFI pump. The VL pumps will easily feed a 128kw 4AGE. Or you could just go with a Walbro in-tank EFI pump, they are also quite common.

[gt500biatch]

thanks :) the walbro one just come in one size or different ?

Walbro 255 (as in 255 litres per hour) is the one I've heard/read of people using. It will work fine but it's a humongous pump for a 4AGE. Stock 4AGE pumps pump 80lph, so I'd try and find something around that, maybe a bit bigger if you want. Walbro make heaps of pumps, try and find a catalogue and get some specs on them.

I think he is taking about my old car, so it is already setup as per my tech articles floating around. That Bosch external pump was in unknown condition when I got it, so I wouldn't be siprised if its past its use by date.

If you have Dave's old car just get a replacement Bosch 070, which is the external VL EFI pump I was talking about early. Will just be a straight swap, no mucking around changing stuff.

The 225 is overkill, but it sounds like your car is supercharged if you mount it externally :P

[gt500biatch]

nah don't want it 2 sound supercharged, its N/A so i want people 2 know they got chopped by an N/A hahahaha :)

[gt500biatch]
