Ok so facet pump, fuel king regulator and a replacement for the faulty generic pump all turned up today. As in midst of fitting a new bathroom car will be another week away but in the meantime suggestions of where to mount the regulator/filter assumes it needs to be mounted to inner wing etc for vibration reduction but just not sure where to screw it to and cant find any pictures on line

Are you referring to the early glass bowl fuel pump...scimitars never came with fuel pressure regulators ,mainly as they're not needed !

The glass bowl was I believe a filter unit. I know scims were never specced with 1 but I'm fitting 1 after an electronic pump to mine and was simply looking for a suggestion as to engine bay location

Nope - that’s the early pump rather than a Filter King.

Mount it anywhere you can get to it, and not in the engine. Off the inner wing somewhere?

I am in the process of locating the filter king in a better place in my engine bay.
The previous owner had already fitted electric fuel pump which is mounted on the under engine cross member without any insulation/mounting bobbins so is loud and annoying.
I see no reason why the fuel pump cant stay where is but a better mounting is needed to quieten it down.

The places I have considered for the filter king so far are either on the bulkhead where the washer bottle is currently, relocating the washer bottle, so the run of fuel pipes is reduced to a minimum or mounting the filter king where ever there is space on one side of the inner wing area.
The fuel pump the previous owner fitted supplies the fuel at a slightly higher pressure than I would like but fuel supply is very inconsistent with pressure spikes when the pump pulses hence the filter king to reduce the pressure but also make the fuel pressure more constant.

Pump I've installed just near the tank and little noise reg I'll fit inner wing away from the stainless exhaust manifolds and hopefully it will fit nicely between coil and wiper wheel box

I’d probably fit the pump and reg in a rear cubby hole with a drain tube?

Mines on the bulkhead.
Previous owner thought it wasn't needed.

I didn't agree with this. Seen too many issues over the years caused by people not using a inertia switch

it doesn’t really matter on a separate chassis vehicle without crumple zones.

I was always advised (by an engine builder) to fit the fuel regulator in the engine bay rather than the boot as the pressure can change along the pipe

that makes sense but I doubt there’s much drop over the 6’ or so (and if there was, you just wind the screw out 1/4 turn :D ) - on an aftermarket setup, I prefer not to have more joints than necessary underbonnet if I can help it but all fuel injection cars would have the regulator on the fuel rail next to the inlet manifold.
