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? |

I know the Holley's are rebuildable.
I rebuilt mine when I was chasing problems... but then ended up buying brand new ones anyways... when rebuilding didn't fix my problem not sure if the Carter is rebuildable... but worth checking. it may have a course screen (filter screen) inside of it. the Holley's do.. again...just in case its plugged (not too likely) the 50gallons must be emptying your cell 5 times over every hour.. has to be adequate... as you are most likely burning around 5 gallons in a 20 minute session... is it possible that without the surge... that your sucking enough air in the corners, to cause the bowls to run low? maybe fill the cell to the brim and see if the problem continues? |
