Anyone running a surge tank? First time questions.
Anyone running a fuel surge tank? Single turbo 5.3 and don’t want to uncover the in tank pump during acceleration and sizing pumps now, using a 1995 caprice wagon tank and I have been told the pump gets uncovered during hard acceleration. I have an ebay surge tank that holds a Bosch 044 style pump, tank only holds a couple liters. I was thinking a 255 in the main tank feeding a 380 Bosch 044 clone in the surge tank, seem like enough? Return from the engine will go to the surge tank as well as the feed from the main tank. Surge tank will be mounted up in the engine compartment. I figure 500whp goal.
Was running a single 450 in-tank which would cause starvation issues when launching in 4x4 at anything under 1/3 tank of fuel. Added a Hyperfuel twin pump surge tank which resolved all slosh issues. I'd never have a turbo car without one now.
You don't need an aftermarket fuel pump to fill the surge. You want high volume and low pressure for that. OEM fuel pumps work great. I used what ever comes in the factory ford 1993 tank to fill my surge. You won't use more than 2 liters of fuel on a pass. And it will be filling the surge tank the entire time as well.
I ran an AEM380, then switched to staged twin AEM380's in the surge. Also nice you can mount ethanol content sensors, fuel filter, fuel pressure, and the FPR on the surge tank. Then have 1 line going to the factory rail up front. Makes for a neat install under the hood.... But a little messy in the trunk. Filtering the low pressure side feeding the surge is nice too. No restrictive filters on your "big pump" then.
Excellent info, so I will stick to my factory pump to fill the surge tank, looks the same size as what you have there, Forcefed86 do you think a single 380 bosch style would be good enough for 500whp? Tank I bought only holds one pump. I plan on using the factory FPR on the factory rails with decapped average 80lb injectors.
