Every post I read seems to state that are Buicks can,t get down the track with out a big ele. fuel pump & 1/2" fuel lines . The "stock appearing" cars have mods to the heads ,valve train ,etc & must be close to 450 + hp for shure , right? Do the cars use larger fuel lines & ele pumps ? or do they have to run the stock type lines & pumps? Thanks Mark
You can go a looooong way with 3/8th fuel line and a good fuel pump. There are aftermarket mechanical pumps that support 500+HP too. I figure I'm running around 450HP (maybe some day I'll hit a dyno) with 3/8th fuel line feeding a 5/16th(!) fuel pump. Though I do think I'm getting near or at the limit of the pump.
