Filter King

[jono]

I've had a Filter King regulator kicking about in the spares box for ages but instead fitted a Sytec regulator in the boot just after the electric pump.

One of the motivations is the Filter King has a port for a pressure gauge as well as, of course, a bloody big filter cartridge!

Where should I position it - up front in the engine bay or in the boot? If up front where is the best place to fix it - I've heard it said the pressure regulator should be a close a possible to the carbs which makes me think I already have the Sytec in the wrong place.

Cheers

If you fit a "Huco" ref: 133010 (2.1 psi) low pressure Pump you don't need a regulator and it's not noisy like e.g. Facet.

Mine's bolted to the 'wing' of the narrow rad so just in front of the carbs

Cheers chaps,

Alan, I have a Facet Posiflow which is barely audible (fitted in the boot of the +2 below the floor on resileint mounts)

Years ago I had a regulator that looks like the Sytec with an adjustable knob. The problem I found was that under vibration the knob would turn and eventually zero itself out with the result that the fuel was cut off and the car would come to a halt. Very annoying. I had it placed in the boot (trunk) near the electric fuel pump.

I now have a low pressure, high volume (and high priced) regulator from Aeromotive:

Also placed in the boot, but no problems as the adjustment is locked and cannot vibrate to a new position.

Hi Jono,
maybe i was just unlucky with a Facet that was very noisy. When i bought the car it was already fitted and as soon as i had driven a few miles the car misfired with fuel starvation. When i touched the Facet pump it was very hot and causing vapourlock. The integral filter was blocked . There was also a pressure regulator in the fuel line.
So i replaced it with the "Huco" low pressure high volume and also removed the pressure regulator. I killed 2 birds with one stone

I have a sytec with a locking nut in my plus 2 boot. Alongside the facet pump. No problem with pressure loss. But I have run copper fuel pipe instead of the factory plastic.

I have a filter King and it is mounted on a rod, fastened in a spare mounting hole of the front Dellorto carb.



RE the problem mentioned with the other regulator, if you look closely you can see that the dome nut is a locknut for the slim nut below it.

The Sytec PR I have has a knob which you need to push and turn over a series of cliks so it will not 'shake' off its setting during use.

One of the motivations of using the Filter King is being able to fit a pressure gauge but i've just noticed mine does not have the drilling for this - I wonder if it can be drilled and tapped to take the BSP fitting?

As a point of interest why are they supposed to be close to the carbs (as I am given to understand) as opposed to being fitted remotely, say, in the boot? If this is bollocks then I may just leave things as they are.

On my TVR 3000M and TVR 3000S the Low Pressure Huco Pumps are in the Boot and no problem 100%.
On my Elan Sprint i still have Mechanical Fuel Pump no problem.

Question for Bill,
with the Regulator on the front Carb how do you remove the Dissy or slacken the Clamp to adjust Timing

Easily, I take the Filter King off its stud and let it dangle from the pipes while I reach behind it, then put it back on the stud with the securing nut loose while testing the dizzy.
