Well, We had our head ace mechanic here for 3 hours today , We found a few issues.
1) 1 bad Russell fuel shut off valve which would back feed fuel from the small 3.5 gallon tanks mounted in the box.
2) Installed Russell back flow check valves in main fuel line from back tank and also in the front tanks.
3) Re-installed Holley HP Billet fuel pump 7.5 psi pressure all good BUT... after 45 min. run time .. NO FUEL PRESSURE Again...... rear lines are Aeroquip -8 an lines / Moon Style tanks are all -6 AN Aeroquip lines also...
4) Also FYI... the tanks are vented and also replaced the TANKS Mustang style tank in the rear also... the 1st tank the pick up tube broke off in assembly ... man am I frustrated .... are the Aeroquip lines collapsing ??
