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? |

it sure seems like that pump should be more than adequate..
any chance the ground wire is loose, maybe its cutting in and out? I had a similar problem 2 years ago.. and never really found it I replaced both of my fuel pumps I had my carbs rebuilt (once by ourselves, and then the problem persisted... so once again by a pro) I replaced 18x Stainless fuel lines with 36 x AN ends. the problem went away but I still don't know which thing fixed it. and we basically replaced the entire fuel system trying to find it, over an entire race season..... it was really frustrating to have the car cut out after 2 laps into a race weekend after weekend... |
