VW addressed this issue in the 90s for some unknown reason. To my knowledge they have never had starvation issues and at one time or another I have owned nearly every FI car they have made from Fuel Infected 74 Super Beetle up to the Mk4 Jetta and I've never understood the need for the twins in regular street cars.
VW usually used 2 pumps to correct the issue. One residing in the tank and the other mid-way between tank and engine. We can't use their in-tank for most installs but Bosch thought the years has created some damn fine stand alone pumps that will take it's place.
The Bosch "044" pump is my go to for primary fuel. At 80GPH@72psi it's a pretty hard pump to beat for the buck. They can be sourced in almost any junkyard off most any Euro auto. Plus of that is that you get whatever mounting assembly they used, which can range from simple bracket to foam enclosed. They used foam as they can be a bit noisy, but a good running unit under light load just hums.

The pump is actually embedded into the tank. Basically it's a "044" without the outer shell in a small plastic tank. It's self contained with all the fittings you'd need to plumb up any engine and tank.
I put the primary with a 1/2 intake hose right beside the tank and the secondary is under the battery at the front of the car. Between the two, unless I go on a skid pad joy ride, should be able to handle any cornering I might do.
Total cost for the pair? $25 Not starving for fuel.. Priceless.
Cheers!
