Hey all,
So this might be a non problem but I had been speaking with the famous @JohnnyTightlips after purchasing his hellcat fuel pump + basket setup.
I had been warned that sometimes the basket may experience fuel starvation if there are too many hard pulls back to back OR if fuel in the tank becomes too low (I was told somewhere between 1/2 and 1/4 is the beginning of the danger zone)
First off, is what I've started correct?
Second, how can I mitigate these issues if they are true?
Was given a lead by Johnny that I could investigate the use of baffle flaps potentially.
From what I saw online, the idea with these is that they let fuel into the pump area but do not let it out, so therefore if the tank is level with no G's then you should get the basket fuel level of X (the height of the tank's fuel level when level under no acceleration). If the car is accelerating then the fuel will slosh backwards and if there were no baffles or basket, the fuel level accessible at the center of the tank (where the pickup is) might be something like 1/2 X. Depending on overall fuel level it may starve the pump.
The flaps would mitigate this problem by letting fuel into an area accessible by the pump pickup, but not allow it to flow away from that area under acceleration.
With this in mind, I noticed that the basket itself has an anti surge flap, but it's only one flap and it is a very tiny flap at the end of a tiny inlet tube.
What I think that this means:
- Anti surge isn't a huge concern for a single unless you really are pulling so much fuel that you drain the whole basket
- Multi-pull fuel starvation issues are more likely due to the fact that the basket itself cannot refill before your next fat pull
If these are true, my proposed mitigation for low fuel tank level starvation / multi pull starvation issues is to cut more holes into the side of the basket near the bottom and seal them with anti surge flaps. This way it can take in more fuel between pulls.
Let me know if this sounds insane
