Hi,
I am having a problem with my 66 Catalina, when ever I go over 60 mph the car hesitates. I also notice it if I lay on the pedal hard. It's almost like it's not getting enough gas. Any ideas? - Nelson |

Clogged fuel filter.
 My Rig's a little old, but that don't mean she's slow.

The fuel filters are new, but I probably should have mentioned that I am just running a electric fuel pump, but it runs at 7 to 9 psi. That should be enough right? I would think so since the behavior only appears every once in a while, it's just gotten worse in the last couple of days. I'm going to put the mechanical pump back in and drive it for a few days and see if that helps, the first suggestion got me thinking about that. Can anyone tell me a good electric fuel pump to use?

I put the mechanical fuel pump on, but I still had no luck. Do you think it's running too lean? Could that be a cause? I've gone through the fuel line for
leaks but I couldn't find any, and I shot compressed air through the line to check for blockages. I've pulled the tank and checked the sending unit, and the filter sock was clean. I'm at a loss here, my carburator is brand new, so I'm wondering if it just needs a little tweaking. If you have any ideas let me know. |

Try pulling the carb and adjusting the float.
Also make sure it isn't rubbing or getting bound up. I've never had anything but trouble with electric fuel pumps. All it does is pass the work to the alternator theres no savings. And forget about limping home with a bad battery/alternator. Good luck, Pitts The corpses of children are called adults!! |

I would check your distributor. The advance might not be working totally right. Make sure the springs are OK and all that good stuff. Also, make sure there are no Bosch Platinum plugs in it. Those suck at speed.

If your carburetor is brand new, what is it? New old stock original; new replacement?
Do you have the surging problem at higher RPM in lower gears? Is the vent for the gasoline tank open? Many older cars vented through the cap. Newer caps may not be vented, causing a vacuum on the tank, and reduced fuel flow. Jon. Good carburetion is fuelish hot air.

The carb is a holley 4160, but I think you may be on to something with the non vented gas cap. I'm going to jump over to the parts house today and pick one up.

I tried the vented cap, but no luck. It's still going even with electric and manual pumps going. Any
ideas, anyone? |

My tank dosen't vent at all and it dosen't do that. Sounds like what my car was doing. Try a new set of plug wires, make sure your vacuum lines are good. Start with the basics. Never hurts to get a new set of plugs and wires. Make sure your vacuum advance line is good and tight with no leaks. Any think like that could cause that. Make sure your carb is good. In my personal opinion Id say dump the Holley and get an Edelbrock.
