If you have a PnP around ya, the mk2 gassers had a in-tank pump that works great. It's low pressure like around 4-5 psi and gets up good.
They use the low pressure pump to feed the high pressure pump mounted where our water separators are.
53willys just finished a gasser conversion and left his in-tank pump in place.
We discovered when we did the first start up that you cant suck fuel though that pump, not even a little. It has to be running to get fuel through it.
I was also looking into the golf 3 with a ACC engine (1.8 8v fuel injected carb) the pump is rated at 1.2BAR = 17 psi. Thats a little too much but I was thinking of running a pressure regulator to set it at 5lbs. But if you say that the mkII pumps run at 4-5lbs I should be able to get one. Is there a way I can test it to see what pressure it runs at before I install it in the car???
Try looking up " Facet " fuel pumps on Ebay. They work very well. I think you can also buy them at NAPA.

I wished I could have done that with my Caravan diesel conversion, but mine was a high pressure for the fuel injection.
Here's a pump for $32:
