Quote: I picked up a summit dualfeed line with filter and gauge and a separate line to tape the gauge to the windshield. I got a constant 4 psi with no drop in pressure,engine still falls at 5 grand. I took theline off and installed it to the feed line and get a chatty 6.5 psi. I also replaced the fuel pump rod with a mancini one.
Ok, Lets assume fuel pressure is OK.
Does it drop at the same RPM in a 3 gears???
1. try the air cleaner off, (been bit twice by that, and its a kwik test,
2. if your running Chrysler electronic ignition you can try another control box, (long shot but again cheap and kwik)
