i was wondering if i need to buy an aftermarket primary fuel rail in order to run th whole system with stainless steal braided lines? And also would i be able to run the fuel system in paralle with the stock primary fuel rail? i searched and found this diagram that i am gonna go by....

 

what system do you have now, big inj. secoundary rail fpr. one or two pumps , future h/p goals?

 

right now i have 1680cc injectors with kgparts sec fuel rail,and sx fpr,and also one fuel pump. i will be going single within the next 6 months just want to get all this stuff out of the way while my car is down for petty stuff.

 

if your ever going to use two walbros in tank run main fuel line to one fuel rail returt to other fuel rain, and charchol canister line return with presure regulator teed from both fuel ralles. but to answer you question i would get the primary rail and fittings from K/G would be easer and less chance of fire!

 

would i still be able to run the stock injectors or will i have to change to 720cc?

 

call K/g monday they are the best ones to find out what you need to do. good luck <charlie>
