This is for the '80 and older Saginaw pumps (both GM and Ford), your Econoline van have the newer O-ring style. If you swap out the high-pressure pump fitting you can use the 5/8-to-AN6 adapter. That's how we're running a Saginaw pump on a F-Super hydro, the older 5/8" fitting (well it's 3/8" SAE flare, the 5/8" refers to the actual thread) with a part-store-special F-Super replacement pressure hose with the 90-degree lower end cut off and the line double-flared, works like a charm. But since you're doing all AN- hoses that's kind of a moot point, just grab the proper o-ringed AN- adapter and run your pump in its stock configuration.
im getting a littel confused here.
so your saying old Fsuper is 16mm fitting?
Like I said Im using a 2006 SD box and I have the lines and pump from it. Pump wont work without custom brackets, bushing making etc. So i want to use a C2 pump since I already have it, just need an F super reservoir. Unless the saginaw really is that much better. But i would need a metric (SD hose) to std fitting converter i believe?
The F-super pump housing is the same as any other C2 pump housing, only thing different is the dual-return-port reservoir and supposedly the pressure-regulating valve and spring (to provide about 100psi higher line pressure). Meaning you can swap valves and springs and high-pressure fittings to your heart's content, they all will fit the housing properly. And yes, the female thread of the C2 high-pressure fitting, aka the port where the hose threads in, should be 16mm. And this is the case for all C2 pumps, F-super or not. What I was directing your attention to is that there are two ways the hose seals to said high-pressure fitting, older ones use o-ring while newer ones have a teflon seal. You need to know what the high-pressure fitting on your F-super pump is before you buy an adapter to AN- hose. And if you can only find adapters for one style of high-pressure fitting, while your F-super pump has the other, then just hit the junkyard and collect the fitting you need off any C2 pump, be it a F-super or not.
The Saginaw is a good pump. Do you really NEED one, maybe not, but since you're on an upgrading spree, and if your pump can stand a replacement, might as well do the switch. Especially since you're no longer tied by having to use factory pressure hose between the pump and the hydro. If you find an AN- adapter that fits a C2 pump and you have a C2 pump that's in good shape then go for that, it should be quite a bit cheaper than swapping out the entire pump. And the AN- hose will transfer from that to a Saginaw pump if at some later point you decided to go that route, there won't be a need to have a new hose made.
Clear as mud now?
