So I bought one of these and I can see where the fuel goes in and the fuel goes out, but there's a vacuum hose connection on the top (shown at 9pm here). What do I connect it to, or do I blank it off?

Is that called a rising rate pressure regulator? I'm pretty sure that vacuum line is for turbo applications so it increases the fuel pressure with boost.

Could be wrong though, haven't had much to do with them.

I'm a spaz. I've gone EFI. Should have looked at Doc's suggestions a bit longer!

Haha. :lol:
My next suggestion for a road car being, WHY do you need one? There are plenty of fuel pumps will feed a 45DCOE enough fuel without flooding it. eg I get by with a stock Facet red cube one.

I'm pretty sure I've got the low-pressure facet pump at the moment. We (in struggling to get it started after the build) bought a high pressure pump thinking it was not getting fuel. Then realised that the 3lb pressure was where it should have been. As I mentioned in the other thread, I've got an interim in line pressure regulator (no gauge) as my mate though it was still getting too much fuel.
