CIS Fuel Pump Options for more fuel!

One of the ways we get more fuel is to bump the System Pressure at the Fuel Distribuitor. However, it might be the pumps can not keep up under higher duty and become the limiting factor.

I believe Therrey found that replacing the front pump with a higher spec 044 he could get more fuel up top out of his stock 91 Turbo FD.

Note that the 413 seems to be the granddaddy of them all.

Found the following info hidden in another N/A post and thought it might be valuable on our quest to get more HP out of CIS and easyer to find with a tittle that might help others find it latter.
