This is the standard Golf/Jetta/Fox combination fuel pump, pressure
accumulator and filter. Used from mid-1980's and up. Should be plentiful
at a dismantler, if nesc.

I have the same setup on the Westy I am converting to gas. I also have
noticed the same problem. I was looking at the Bentley, and I noticed
that the Golf had a "transfer" pump from the tank to the chassis mounted
(3-component) pump. I decided to simulate this by buying a "universal"
low pressure pump from Pep Boys between the tank and the Golf pump.
There were several models, and I chose the one with the lowest psi
rating. It gets it's power from the same fuel pump relay (just like
stock) as the 3-component pump. The main pump runs quiet, but I can now
hear the new pump. I'm thinking of rubber-mounting it.

I know this works better because I now get a good flow of fuel on the
return line to the tank. I used to get almost none.

I'll post pictures of the setup on my website soon (a few weeks or so)!

Thanks!
