I removed the stock fuel rail as was looking for cleaner look and installed some pipes was planning to make a fuel rail but couldnt get appropriate size and AN fitting here we get only limited parts here in dubai so difficult to source. Anyhow manage to put IN and rerun and the problem I am getting is flooding in the carbs changed the settings on regulator but not working can cross check any fittings if pipes are fitted ok or not but whats happening is fuel is returning more and carbs are not getting it enough, as soon as we put the stock fuel rail it works and with these pipes it doesnt work

 

Any suggestions would be appreciated.

Does the Stock fuel rail have a smaller return line? looks like your new set up has the same size feed and return line. Hard to tell from the pictures.

It's the same size till the cords member where stock pipes are there as from there return is smaller.
