Rb20 Fuel Pulse Damper Vacuum Feed

[mrsr32]

where is the vac feed for the fuel pulse damper suppose to come from? can it come from the one on the throttle body as from what I've read it has to come pre manifold.

just swapping motors over and the old one didn't have one, just had the fpr at the front.

thanks in advance

It would need intake manifold pressure, not piping pressure. Plumb it in after the throttle.

Tee'd off the FPR signal if nothing else.

thanks didn't have a hose long enough so tee'd it off teh boost gauge feed at the back of the plenum for now.

not ideal i know.

does anyone know where it plugs into from factory?

[GTSBoy]

Where you have it is as good as anywhere else.

[mrsr32]

Given the choice of a rail without the damper which one is better?

one without the damper or one with the damper?

[GTSBoy]

Who cares?

Who cares?

That's what I am thinking. Their usefulness is very questionable.

sweet, i'll use the rail without when i swap injectors, one less vac hose to deal with.
