boost referencing... and stuff

alright, so i got my rtx-1 thing running, just curious about how everyone else runs lines on there t-rx1's for your fuel pressure setup.

I have 1/8" lines with t's running from the nipples on each of the carb boots up together then into the port on the side of the fuel pressure regulator. I just used standard 1/8" vaccum lines sip tied onto nylon t fittings, obviously im not going to build much boost on the stand at home, but im not seeing really anything happening with it, just making sure i didnt totally brain fart.

If your worried that your afpr isn't working, or want to make sure it is, get a random hose that you can hook up to the regulator boost ref port, get a automotive tire stem, plug and ziptie on the other end of the hose. Set your air compressor to like 15 psi, hook it up to the hose and you should see the fuel pressure jump. Ie if you have static fp at 4 psi it should jump up to 19 psi on your fp gauge if your air compressor is set to 15 psi.

This should at least verify your fpr is working. Sounds like your vaccume lines are right, so once you can get the sled to build boost (if you can't in the garage and need snow) just have your fp gauge mounted such where you can see it and make sure you are geting adequate fp.

i have my regulator sitting right under the meshed out dash with the gauge right so i can watch it, so that helps a LOT... i will try the air compressor setup, i rigged up the regulator from my spray gun with a nozzle on the end so i can test things like this! i think the spring inside of it is to strong, the guy before me did some interesting stuff to the parts I bought used off him! worst comes to worst, i could get a new spring from mallory.
