so i have lq9 with l92 heads i just bought some edlebrock rails and id was wondering is it necessary to put a fuel pressure regulator or do i bolt it right up i currently have 42# green tops

 

Regulator is in the tank for 99-02 LS1s, so no you wont need an external unit

 

fool ur car aint fast enough for a regulator

 

yeah ur right lol I was getting schooled here at work is the reason I ask is because they were saying im going to need a aftermarket one due to the fact it was only going to be at 58 psi and with a aftermarket one it will work better? or something like that

 

hahah im jk man, i wouldnt get a reg. the factory one holds to about 650ish

 

cool ill have to look into that! thanks!
