the stainless lines that wilwood recommends for the fronts fit fine, actually a little longer than i would like but the shorter version is to short. for the rears the lines wilwood said would work, were to short and i had to get a new set that were longer. i'll measure the length over the weekend and let you know the correct length.

 

Do you have any other pics or info on that fuel line. I couldn't see what was different on it.

 

Nice build btw..

 

here are more pics. the check valve with the 4 pin holes was in the fuel line,which really slowed down the delivery. that valve has been eliminated and now flows straight through.

 

very nice...!!

a couple of questions:

what did the fuel line cost?

who did the tune? what tuning software? hpt? efi live?

what kind of dyno for those numbers

thx

 

Thanks!
Fuel line was $100 from custom built motors "CBM"
Tom VanVugt at izzy performance and it was done on HPT.
Mustang dyno.

 

So all you installed was the LT-1 Injectors and the fuel line and the fuel starvation was fixed? What abut the LT-1 HPFP?

i also installed the LT4 cam which has a larger fuel lobe. at 9psi and fueling has been fixed.

 

Oh ok...I didn't know the tri-lobe was larger. Thanks

i just noticed you are running 305/45/22's. your wheel is a 22x9 stocker, correct? how do you like the ride? any negative side effects to running that wide a tire on a 9inch wide wheel?
