Title: Additional injector feed
Post by: McCARTHY on February 19, 2006, 05:07:02 PM
Right this ahs been bugging me and do forgive me if this is a stupid question....

Now, You have the stock in tank pump feeding a swirl pot, this feeds 2 bosch 044\'s (or similar) which inturn feed the injector rails. 1 pump for each rail. If you have additional injectors mounted in the plenum where do you get the fuel supply from???

You have to Tee Piece into the rubber hose fuel line and take a feed from there, you will need to get some braided fuel hoses, and an after market fpr that allows two inputs

yeah i got that bit, but when you run a twin pump system you have 2 fuel lines coming from the rear of the car. One for the primary rail one for the secondary. Which line do you take it from??? Do you  tee into the secondary as the addittion injectors would come on line at the top end of the boost curve?

you have three lines there actually running underneath the car, one for Fuel feed, one for fuel return and the other for the fuel vapour system, use the fuel vapour line as the additional fuel feed line for your secondaries, use the original line for your primaries and Tee into that for the additional injectors
