fuel filter

Hi

I have a defender 90 1988, with a3.9 v8 efi possible from a disco but not sure im have some problems after changing oil. its now very hestitant and a bit slugess I cleaned the maf today which helped but still not sorted. I was thinkinh of changing the fuel filter but i cannot find anywhere. i followed the pipes and still no luck can any one help please

If you have followed all pipes then maybe it didnt have one fitted during the conversion

Hi thanks for you reply. Could this mean that some diet has got through and slightly blocked something. Would you recommend a inline fuel filter?
