Intercooler Tank Piping - Help
The car's in the shop next week to install a Pierburg CVA400 pump in place of a Davies-Craig pump, which means doing some piping rework. While it's there, I want to straighten out the tank outlet and inlet fittings and pipe.
In the first photo below, the inlet is on the top and outlet on the bottom. The outlet threaded nipple is 1" OD, but necks down to 3/4" at the 90 elbow. This just ain't right. Every 1/8" makes a huge difference in flow rate. Why can't I just cap the current outlet and cut a 1.5" outlet hole in the tank and install a straight reducer coupler hose (second pic below) and come off of that with a 90 coupler hose (third pic below) and then use the largest ID pipe possible? My setup is way too restrictive now. Suggestions?

A big ass site like this one is full of racers, and not one's a plumber?!

If the outlet nipple is 1”, why not just carry that all the way down and back…? Upsizing to 1.5” out of the tank is unnecessary.

The reducer idea should also work on the pump discharge.

Of course, which is why I'm putting a Pierburg on it, and will change out the outlet and inlet fittings. PVC should work better.
