hi guys,

i've bought an adjustable fuel pressure regulator from burton power, same as this one:

http://www.burtonpower.com/parts-by-category/fuel-system/fuel-regulators-injection/wfr505.html

with a standard inlet manifold, the small silver tube would be connected via a hose to a port on the manifold for reference pressure. my manifold is a homebrew so i'm wondering what to do with it. a mate with a duratec'd mk2 escort has his going into a small, sealed, plastic container. is what i'm after a vacuum pressure like this?

any suggestions?

Do you have a vacuum connection for a MAP sensor, if so run this to a small plastic container and form a vacuum plenum and then create two connections from it one to the MAP and the other to the regulator.

i don't think so. the manifold is a very crude homebuilt affair made by the previous owner - one large dia. tube with 4 ports going to the head, one end blanked, the other connected the the throttle/air filter assy. it has a throttle position sensor and one embedded in the filter which i assume to be the MAF or inlet temp sensor.

haven't got to grips with what ECU its running yet, just driving it until i accumulate the rest of the bits i need to fit the jenvey's that came with it.

would putting a hose just between the reference port on the FPR and a sealed plastic container work? what is the effect of running without the reference pressure hose?

I would leave the vac port disconnected if i was you, no real need to have it connected to the manifold. Assuming your ECU is aftermarket it can be re-calibrated to suit, you will need to do this anyway if you modify the car further.
