A stupid question :) :)
I've a Petrol King Fuel Pressure Regulator fitted.
the question is where should it be fitted.
should it be between the fuel pump and the carbs, or between the pump and the tank?
i've placed it before the pump and in a position that is hard to get to

thought so i must have been having a brain block that day and then totally forgotten about it.
the thought hit me when i was out for a drive this afternoon. the car elt that it was suffering from fuel starvation and it remembered that i had not
even set the regulator and it was at it's default postion. i think that it is 1.5 bar and the car needs 3
i just need to get a pipe connector to join the two pipes together

I fitted mine in the engine bay on the passenger footwell front.
You need one if you have an electric fuel pump.
If you are using the mechanical pump, I don't think you need the filter king.

DO NOT SET IT AT 3 BAR!!!!! That'll blow the carbs apart! 3 PSI is, however, much nearer what you want, and maybe a little less, depending
upon set up. As said, most mechanical pumps tend to put out this pressure anyway, but some do vary.

sorry i ment 3psi
3 bar and BOOOOOOOM
the presure regulator is out of sight and thats why i forgot about it
i think that it is this "obstruction" in the fuel lines that are causing my problems. the car stutters and acts as if it is running out of
fuel before hitting 4K and then the RPM just rises fast.
well i will remove the restriction and see if this cures the problem.

Sounds like it need setting up actually! If it'll rev past the point where it stutters it can't be a lack of fuel, merely a wrong jet
selection.

it's not totally free reving above 4K, it's just less noticable.
i bought the engine fully built and ballanced from Vulcan Engineering. they knew what the application was and so i trust that they put in the correct
jets
every time that i run out of petrol, or the float chambers run dry because the car has stood still for so long i cannot draw fuel through from the
tank. i have to take to top off one of the carbs and fill the float chamber with petrol. the car then runs on two cylinders untill the pump can draw
more fuel through. this is due to the engine running faster.

I had the top of the regulator/filter and there is some sort of rubber bladder that and a screw that presses on soemting whcih adjusts the
pressure.
This looks like the diagpragm set up you find in an oil filter to stop them draining so I suspect that the regulator works best when petrol is being
pushed into it i.e. it sits after pump but before carbs rather than having petrol sucked out of it i.e. like you have.
as ^^^^ said, is fits AFTER the pump but BEFORE the carbs.
