Supervee pressure regulator

[Lastminuteracin]

Looking for an adjustable fuel pressure regulator for an injected supervee like the one in the picture. Thanks

I think Pressure regulator from any car would work on this.

It seems the original Bosch unit is out of production. I’m trying to stay period correct but may need to go a different way on this.

Check BMW 2002 tii restoration sites they used the same pump and accessories.

Is that the same pressure regulator used in VW type3 D-Jet injection systems?

like this one?

may give you another parts stream

So I was able to source an original style regulator. They were converted to AN-6 lines. Any idea of how that’s done?

I would guess if had the tubes cut back (remove the bulge), a male sleeve nut installed and the tubing flared to accept the femail AN hose? Not much room to do that.

short piece of hose and a barb-AN adapter would be the easiest.

the return does have threads so it’s possible to use that as an adapter point - just make SURE it doesn’t leak!

I do see 5/16 compression to AN fittings but like you say I don't think the depth is going to be long enough. Is a barb to AN with a short section of hose going to pass inspection?

Injection hose (available at any parts store) and single ear stepless oettiker clamps will suffice. Just make sure you use the stepless as the standard 2 ear clamps aren't good for low viscosity fluid sealing. And as the cylinder heads are non-crossflow, things can get warm near the intake. So cover the hose with firesleeve when it gets near the manifold.

I didn’t look for a compression type adapter, there should be enough meat on the tube for that (not positive, but likely)

rules are going to dictate what hose connection is approved. Most ‘threaded fitting’ rules are based on the pressed in nipple, like on carbs. We still use hose and hose clamps after the fittings. Your nipple is welded steel and should pass inspection if the proper rated hose is used. Check with the groups you run with.
