can you plug the holes where the 2 crossover tubes are on the 93 fuel rail, then drill and tap a 10an fitting and run braided hose???

 

Why not, just don't see any advantage besides it looking cool.

 

i am having some problems with the stock crossover's. plus i will be running a complete fuel system later this year that will need the front of the rails taped for 10an as i will be going with braided hose tank to rails.

 

Go for it then. Worst comes to worst, your out 50$ for new rails.
