Looking for a supply source for some TBI fittings. Working on installing a carbed 383 into a '90 K5. What I am doing is using the stock in-tank pump/lines/filter. From the filter on I will replace with braided line and JIC fittings to the regulator and carb. Need female fittings on the end going to the factory lines and NPT or JIC on the other end. Anyone done similar?
