I'm having a fuel pressure issue after being on track for a few laps. It seems like the float bowls are being sucked dry....
Current pump is a Carter I believe the model to be 4060. This shows to be a 50 GPH pump. The car has 46 IDA webers is 2.5 litre high compression. ...also have a 2.8 that I run sometimes. I would think 50gph would be enough so maybe something else is going on? Anyone have any thoughts? |

FWIW the most recent of several fueling issues I've had was an intermittent wiring connection to the pump, which took a while to find. The symptom was similar ie everything fine then suddenly no fuel, then fine again.
I've been running the Holley Red pump which is rated 97gph with a 2.7/Weber46 engine and no volume probs whatsoever. Also have the PMS/FuelSafe cell which works well in terms of sloshing and pickup. Two filters, large one near the pump and small inline one just before the carbs. Previously I have also had clogged jet issues which are no fun either, but nowhere near as bad as total fuel cutout. |
