Midyear CIS WUR change

[nomore]

Hi all; I have a 74 2.7 with a 001 WUR. Car runs fine but I would like to get a vacuum assisted WUR and lose my Throttle position regulator. I am also trying to move to
using polyamide fuel lines instead of rubber and hose clamps. I am thinking an 009 WUR or 033 for a 75 or 76. Any thoughts. Thanks, John.

Does your throttle body have a vacuum port? Maybe for the distributor, but does that get its vacuum from the same position in the throttle body as the '75/6? You might check to see if the TBs are the same as yours.

the 033 uses manifold vacuum for WOT,
if you need a throttle body I may have one you can have. (i am not on here as much)
I put a 3.0 TB on my 2.7
its a little bigger and lets more air in at WOT.
if the CP is not the same then make it adjustable so you can set it for what you need

I am surprised more people have not done that.
would like to see if it dynos any different.

Funnily enough I do have a two vacuum port throttle body I could use. I believe people run vacuum off the decel valve as well. Thanks for the info. I am leaning toward the 033 and making it adjustable, the pressures w/ the 001 are kinda close. Also importantly I want to change the fuel lines around the motor to banjo bolts instead of clamps. Thanks for the help guys.

In case you need to buy the Polyamide lines & fittings, I keep them in stock.
