Default In-Tank Pump
Can anyone offer some advice on a good in-tank pump for an LSx motor?

I'm running a Walbro 255 with a dead-headed system. I had done quite a bit of reading and it's a VERY popular pump for boosted late model Mustangs. If it works for them, I'm sure it will be happy feeding my LS7.

My understanding is Bosch makes a nice in tank pump with the screen built in.

You need to size the pump to the HP desired. What is the expected HP of the engine?

Seriously though, it's not loud at all. I'm sure that with full exhaust, I wouldn't hear it.
