19j injector pump fuel timing question?

Hi All, hope you can help once again?


I am putting the cam belt back on my 19J after having the fuel pump reconditioned and have aligned everything to the TDC dots and arrows, question I have is this. On the fuel pump cog there is an F mark. What does this relate too, I find no mention of it in the work shop manual, any thoughts?

I think it stands for the F'in correct position...
