Any particular reason I shouldn't do this, adding a boost-reference port for my blow-through setup? No sense spending an extra $60 on a Mallory regulator if I don't have to.

I'm currently running an Aeromotive regulator (its not a return style, just the basic 13205 p/n). I decided i wanted to return the fuel back to the tank w/o spending $150-200 on a new one. I did this by just simply soldering a holley jet in a barbed fitting that I bought from Advance (the jet fits perfectly inside the fitting). I put the fitting on the 2nd outlet and I've been running it this way for about a year now w/ no problems.

Do you recall the jet size? Thanks.

I think its a 61.
