Red Headed Stepchild-75 Swinger LSX Swap
The only option I can see to beat the price of the Tanks Inc. setup is below
1. AEM 380lph inline pump - $110-150 off ebay(this pump only because I'm going turbo)
AEM 50-1005 High Flow In-Line Fuel Pump 380lph -10 AN Female Inlet -6 AN Outlet | eBay
2. 2 in1 Filter/regulator - $69.99 with fittings(39.99 without)(this is similar to the corvette regulator/filter combo that is commonly used on LS swaps)
Speedway GM LS V8 Fuel Filter/Fuel Regulator Kit, 58 PSI
3. 12 gallong fuel cell/with sending unit $75(vented feed and return already plumbed) - Craigslist
4. various hoses and fittings for routing to engine and back to tank- $100
total of about $395 and have it plumbed and all run together to the cell and to the rail at the 58psi that the LS needs.
If I was shooting for a max of 500hp from Speedway has a kit for $189 that you could pair with a cell and then just get lines and be good tog o.
