i'm currently running the stock pick up which runs into a fram filter then into a holley blue pump. this is all mounted to a bracket that makes it level with the bottom of the tank. it runs to the regulater which is mounted directly in front of the bowls. i want to add the carter 172 pump and keep the blue pump as a pusher when racing only. any problems with the carter sucking thru the holley? all fuel lines are the stock 3/8". mike

Don't know about the Holley,but my carter 120 gph sucks thru the comp140, have to have the Comp on when racing though.

well the fuel wont suck thru the holley blue i have had this set up listed below and it just wont do it.

fuel cell with filter running 1/2 line into a holley blue.running 1/2" line to a holley street strip pump....3/8"line to regulator set at 7 psi....and 3/8" to carb and one to the nitrous plate.....

when driving around town the manual pump would not pull enough fuel thru the holley pump so i would have to kick it on and shut it off.....then a few minutes later kick it on and shut it off.......with out the holley blue the manual pump would carry 7 psi with the holley elec. pump it would carry 7 psi and then fall as i drive then i would have to kick it on for a few seconds.......but i didnt change it for years and drove it this way....going down the highway i just left the loud elec. pump on.......

at the race track with 10 sec 1/4 mile times on nitrous it never went below 7 psi with elec. pump on.....
