Just thought I'd let ya'll know if you're replacing your TBI engine with an LS1, you'll need to upgrade that fuel pump.
I just happened to be looking thru my summit mag and this one will do just fine, it's the one i run in mine. It's a direct replacement for 98 and older trucks.
summitracing.com PN# GRN-GM722-2 i didn't buy mine from there but it's the same one.
I posted this because i was chatting with someone and it reminded me this might be a common question.
later,
