ae92 efi fuel system.

Hey just a quick question,

Is there any difference between the fuel system found on an ae92 CSi model and an ae93 sx?
Would the fuel pump in the SX be any better? or exactly the same?

Thanks in advance.

Same on all the EFI models

yea that's surprising considering the CSi got the 4A-F carbie and EFIs.. and the SX got the 100KW 4A-GE...

the fuel system's the same.. but injectors and that are slightly different from memory.. as for the fuel pump, all 4A-GEs i've seen have their fuel pumps replaced upon age with that one from a VL (turbo or non turbo is the same, just turbo costs more)... which does a very good job..

I thought as follows
SE 1.4 carby 6A-FC
CS 1.6 Carby 4A-FC
CSi (and Limited) 1.6 4A-FE
SX 1.6 4A-GE
CSX 1.6 4A-FE
RV, Ultima 1.8 7A-FE

The Fuel system on 4A-GE and 4A-FE are the same. The Carby ones are quite obviously quite different (low pressure lines and no in-tank pump and no baffles in the tank.)
