it is supposed to go between the pump and carbs, if its before the pump, it cant get enough, electric pumps dont suck as good as mechanical. bill
Put the first fuel filter close to the tank outlet and between the tank and the electric fuel pump - to protect the pump. In my case there is a nice little storage spot on the platform just inboard of the right front wheel that holds my filter and the elec pump. Easy access.
I beleive most of us also have a second filter in the engine compartment, just before where the gas line splits for the two carbs (assuming you have two carbs).
Pressure drop through two filters with an electric pump is not an issue as most pumps deliver way more pressure than what our meager displacements demand. I would give serious look at a fuel pressure regulator mounted in the engine compartment, perhaps just downstream of the secnd filter, close to the carb(s). Enjoy.

Mine is just before the pump, to protect it. Both are in the front of the car, inside the right fenderwell on the gusset plate.
The fuel pump is on its own circuit, powered from the dash with a guarded switch.

The peril in putting a tank outlet "filter" before the pump is ; if it clogs even partially/intermittant, your (electric) pump will wear out FAAAST
All that is recommended is--Shazam-- a screen !! (VW knows best)
Nowadays called a Strainer or sock

ernie, i cant make it.
I recently purchased an electric rotary fuel pump from CB Performance - had one for 18 years with no problems and loved it. The only reason I'm replacing it is because the car has been sitting for 1.5 years and I wanted to go with a new one with the new engine. There was a filter enclosed/included and instructions that said the filter must be installed in front of the pump.
Electric pumps WILL self-destruct if they either don't get enough fuel or get crap in them. A chunk of rust/dirt/whatever will destroy them. You really need a pre-pump filter. All the instructions for electric pumps I have seen say to use one.
Also, you know the nylon/plastic sock/screen that goes inside the tank? The ones made today combined with today's fuel will melt and end up in your carbs. Ask me how I know!
I also have a filter at each carb, besides the one up front. My front filter screws into inlet of the pump, and it came that way!

The stock VW tank outlet screen , vertically mounted inside the tank will NEVER clog cause the slightest vibration/gas agitation cleans the screen the particles collect at the bottom.
So you remove or flush the tank every 15 yr. NBW
Any INLINE filter will clog muchmuch faster. At best a questionably worthwhile maintenance item to regularly replace.
Again , stock VW design shines brilliantly , and BONUS ; its metal !!
Obviously I'm late to this thread. Been in Laughlin NV for 4 days.
As stated, run a filter ""BEFORE" the pump and, run a filter after the pump. A sturdy in line metal filter works best as the metal won't break as can happen with a plastic in line. DON'T run one of those small in line plastic filters, I think chicken wire will filter better than those filters. Just go to NAPA or Pep Boys or any auto parts store and look around for the filters. Buy 4 when you do so you have replacements. I usually remove the filter in the gast tank as they too are crap.
