347 FI Fuel Requirements

Discussion in 'Fox 5.0 Mustang Tech' started by DonMaximo, Dec 29, 2007.

  1. Will the stock 5.0 fuel lines and tank pickups support the operation of a Fuel injected, NO power adder, 347 stroker ?? -OR- should I consider upgrading entire stock fuel lines.

    I've upgraded my fuel rails and fuel pump and plan to use steel braided lines and connectors from engine to fuel lines.

    Thanks in advance.
  2. there fine. and if you are not adding any sort of power adder more than likely the stock pump will work to
  3. Thanks for the reply.

    I've been told by most people that a 220LPH is best to avoid any fuel starvation under heavy load
  4. they told you right
  5. I would run a 190 lph + pump for a nice 347.
  6. I ran a 331 stroker for a season b4 I jumped up to S/C and found that a 190 lph was needed
  7. I have run a 190 and just switched to a 255 when I had the gas tank out anyways. You are fine with stock lines up to around 525-550HP I believe.
  8. I have a 347 stroker on my car. I ran a 255lph pump with a 3/8 fuel line to feed rail and stock return.:nice: :eek:
