fuel components upgarde for 427sb

[jrohrig]

getting ready to make a purchase for the fuel components that I will need for my build. I have a Holly Sniper efi hooked up to 427 small block that has 495bhp. I have done a bit of research read the holly sniper manual, and read a few build threads to see what guys are doing. Not sure exactly how its all gonna fit so any help making sure I get al the correct components will be helpful. Based on what holly recommends and what I have seen other guys do, here is what Im thinking so far:

* 3/8 ptfe braided fuel lines for the entire run, both supply and return.
* In tank Hanger from Proam: Walbro 340 (255 liter) fuel pump

not sure which fuel filter I should use and also not sure what fittings/adapters I should get
Thanks in advance for the help

I have a 427. I used an Aeromotive Stealth 340 pump #18638, 3/8 ptfe from Hot Rod fuel hose, Aeromotive canister fuel filter #12317, and Aeromotive fuel pressure regulator #13130. I removed the regulator from the Sniper and used the Aeromotive instead because of possible problems with the Sniper built in regulator. I also used Aeromotive fittings for the pump and filter and regulator. The pump uses an ORB fitting.

Thanks Bill, great info. What are some of the problems you came across with the sniper regulator?

If you're at 495bhp you want to make sure you have plenty of fuel. The Walbro and ProM hanger are both good choices. #6 AN for the fittings. Summit Racing has good fuel filters, and PTFE hose and fittings.

I used the Earl's Vapor Guard hose and fittings. Went together fast and easy, price was acceptable.

I like the idea of going with a Walbro pump as they are fairly generic and thus more readily available if I'm broken down somewhere.

100 micron filter between the tank and pump, and a second filter (10 micron) just before the EFI inlet.
