I'm in need of fitting a pressure reg to my twin 40 idf set up. Currently I'm running directly from the pump.

I'm looking at this currently

Does anyone use this or have used similar?

I have never used one and am a bit confused as to how it is adjusted and how the pressure is read.

I've fitted the 'Filter King' version which, as the name suggests, includes a filter within the unit, to many different cars.

In order to set the fuel pressure (adjusted via a nut on the top of the housing) you either need to add a pressure gauge to the regulator itself or incorporate one in the fuel line.

Here's the type of set-up I use:

Thanks.

Due to the high probability of me breaking the glass bowl I've just ordered this

and a gauge for setting the pressure.
