I use a holley, keen on a mallory though.

Su’s have ver low inlet pressure, too high and it blows past the float. Either need a regulator or a pump designed for low pressure.

Regulator is your friend. No pumps exist that put out enough flow and are also low pressure for a decent rotary.

I'm still open to the bucket with a hole in idea

Those Mallory pumps aren't cheap are they!

I now can't hear the rev buzzer over the exhaust, wtf am I doing so I wired in a 10mm LED to remind me, yes it has a resistor on

Mega pump hunt continues

I'll be selling my trusty holley blue pump, and can sell the non return reg also. I'm switching to a mallory and return style reg, which is a better set up, but the blue and non return reg has worked decently enough for me for a few years in a few different cars. Only complaint is it's louder than I'd like.

Okay, you've convinced me. How much?

I'd sell the pump, gauge and 1-4psi regulator for £140. I think I have fittings on it for 3/8" fuel line too, which is what you'll want to run ideally.

My new pump hasn't arrived yet so I can't take the holley off just yet, but it's coming off soon when the new one gets here.

While waiting for James to send me his fuel system

Been busy on other things. Up first for your viewing pleasure, I machined an extended float bowl for the SU carb.
The original "cap" holds 35ml, this new one holds 87ml

Also been playing with spoiler ideas with the aid of a borrowed 3D scanner and some work in Fusion360
I've yet to 3D print some section to check fitment to the body and get a feel for it in the flesh. If it works I'll probably print the whole thing in ABS, skim with filler and paint.

Yes it's not aerodynamically sound, but it's more about the aesthetic.

Peace and love x

Mean as. I do like a bit of machining. I'm a no spoiler kinda guy, but I like the creativity behind yours aye

Does anyone know the oil feed line fitting size that goes into the turbo?
