Can't seem to find the differences between the stage 1,2,3,4 fuel systems... I can see the 1 is more a direct bolt in without tank removal and the 2 needs a block off to be installed so the one side tank needs to be dropped... But what about 3 & 4? Plan on adding a clutch @ the same time so was thinking it was a good idea to go with the higher stage because 1. It'll save labor because trans will be dropped so tank removal will be easily accessed and 2. eventually I'm gana build the motor and I wanna be set for future power! Do it once do it right... Any help would be great - Eric
I would call Doug or Chris and get a proper explanation of the differences.
I'll hit them up today when I have a sec... Just figured Doug checks the forums a lot & would see this thread... yeah I def need a proper fuel kit... Had the Vette out Sunday and after driving for a lil if I'd get on it fuel pressure dropped to around 40ish! The 60s and BAP isn't cutting it...
You would be fine with the stg 1 fuel system which does not require dropping the tank. Install is fairly simple and only takes a few hours.
Stage 2 requires dropping the tank to install the fuel pressure regulator block off so a boost referenced regulator can be used.
Stage 3 replaces the Bosch pump with an A1000
Stage 4 on up is somewhat custom at that point depending on needs. New lines, rails, Eliminator or A2000 pump.
Ok cool... Saw on your site you can upgrade the stage 1 pump from the Bosch to a A1000 do you see any upside to that? I saw the A1000 @ marks shop and It made me want it lol how much more labor hrs would it be to go stage 3 while a clutch is being installed? Because what I want now is stage 1 plus the stage 3 A1000...how much hp can stage one handle?
