What is the difference between the two?

 

Well I found out there is no difference just one can be bought brand new for under 230

 

The ford cheaper?

 

yeah on fordracing123

 

i really like the g302 injector. ive used it several times on c6 vette builds. plus, greg banish provides all the data in his tuning dvds. keep in mind that it is a bit taller than the factory truck injector, so you will have to space the fuel rail.

 

Yeah I use the same injector but the longer version on my mustang, I was readind that a spacer is needed which is fine. Is there any leaking with the spacers? The spacer is needed for the rail mounts right?

 

yeah, the spacer would be to move the fuel rail up to compensate for the taller injector. so there is nowhere for it to leak with the spacers.

another thing to make sure of, since i have not used these on a truck manifold, is that the o-rings seal properly in both the rail and the manifold. i know they drop right in on a ls2 manifold, but im not positive on the truck one.

 

Those are 47 in a 3 bar application correct? What are they in an LS?

 

Should be 47 lb/hr at 39.5 psi which is Ford's fuel pressure. Use the Bernoulli equation and that would have that injector flowing at about 57 lb/hr at GM's 4 bar (58 psi), actually 56.9499 to be exact. That is if the flow specs are dead nuts on 47 at the 39.5 psi.

 

this is the best spec I have
Static Flow Rate @ 43.5PSI (300kPa): 51.72 lb/hr = 6.52g/s = 544cc/min (+/-3%)
