The gerotor type pump is what I am really considering - if that's the way I end up going

I just spent the best part of the last hour under the car with a tape measure and a short chunk of 3/8 tubing. While I've made other errors in judgment while building this car, this one may prove to be the biggest pain where I sit since it is mostly assembled, wired and (was??) within a week of first fire. There just is not a lot of room between the rails of a Model A (TCI) chassis What makes it worse is that TCI installed the motor mounts over an inch too far back, then Brookville supplied a 3" recessed firewall instead of the 5" that I ordered and of course needed major surgery to work. This forced me to install the steering column lower then I wanted, all of which has conspired to tighten up every thing space wise. I really want to use my mechanical pump rather then an electric as just installing it will mean LOTS of on-my-back work and time (and more then a few dollars). The costs - not as much of a big factor as just doing it in the time frame I've set for myself and with as little "personal pain" as possible.

I'll 'keep you posted'
