Sorry for doubble post, phone is crazy.

I do plan on using diesel to start stop the engine. Being that the truck has 2 tanks stock seems to make this easier. It also has the fuel bowl supplied by a selector valve. The plan is to use that switch to switch fuels. But since there is a fuel bowl that holds much fuel and is prone to leaks and generally on the 94-97 forum everyone hates them. I would be doing an e fuel setup simmiliar to what later model superdutys came with. Skiskyjason described it very well once at least.

Basicly using 2 superduty fuel pumps and check valves to switch fuels. I just do not want to rely on a solenoid and timeing for the return. I would rather block the backs (front) of the engine and force feed the injectors.

Sorry back on point, the whole fuel system will be removed. It is 20 years old. With all new aluminum lines. And now thanks to you aluminum valves and fitting. No offence but many thanks.
