Code 43

[brough]

My 91 ex automatic is giving me code 43. What is causing it to give me this code?

I've two manuals and they don't tell me anything about that specific code.

It is the fuel supply system and I've replaced the filter. I have also run some fuel system cleaner through a few times.

Any suggestions,

Thanks for your help both now and in the past.
