EFI Bung in head update

SlantSixDan, Thanks for the link to the SAE paper. Great to get one free, since one usually has to pay ~$20. Good to have you back posting, somebody was looking for you last week with a slant question.

pishta,
Your fuel design sounds similar to the setup on Euro cars with the Bosch Jetronic system - M-B, VW, Audi, ... They have a sub-assembly mounted forward of the tank w/ fuel pump, accumulator, and regulator in one package. You can find photos on ebay. However, the parts aren't cheap. I got 2 of those fuel pumps cheap on ebay ($15 new), Walbro's version (smaller than Bosch). I had to buy the banjo fittings on the outlet, from a DeLorean supplier (they used Jetronic). I put one on my Newport 383 a few weeks ago after the Holley gear-rotor pump got flaky. I think they run ~50 psi for Jetronic, but I run it at 18 psi in my Pro-jection.
