    TBSS fuel setup

    Hey guys Im doing a motor swap in my buddy's TBSS. He had oil starvation and destroyed the LS2. He had LME build him a 416 LS3 stroker and it dynoed at 607fwhp. I figured a 340 would be enough pump for him. I plan on running a drop in 340 with a bulkhead fitting on the bucket hat, then -8 to the rails to a regulator then use the factory feed as return. Does anybody know the part number for the correct 340? Also what has to be modified in the bucket to make it work correctly, as far as cutting and what not. Thanks!!

    Thanks for the replies guys. a 400 would work. Does anyone have a link or part number? Id rather just do a single and it has to be intank. Thanks guys!! Its going to stay NA with maybe a little nitrous later on so the pump doesnt have to support FI power levels just NA

    400? How about an 044 Bosch pump? I run two of them for big boost. Google Bosch 044 fuel pump.

    thanks trav. I wonder how that would fit in a TBSS bucket. Those things came with walbro 255's stock. I didnt know that

    I dont know what the difference is between the TBSS and truck bucket is, but I know that a few guys have made that pump fit in the truck bucket.
