En Summitracing.com vale US$ 114.5
Part N° HLY-522-40
Fuel Injector 90 PPH for 1-bbl Pro-Jection #501-1, and 501-2
El inyector que trae la Projection 1D es de 90 libras por hora de caudal (pph), y tambien hay de 69 y 64 pph para la misma. No sería tal vez mala idea comprar uno mas pequeño para probar y contar con una mezcla no tan rica....

We have also experienced symptoms of an overly rich fuel mix (blackening of tail pipe, smoke) since the install. This makes sense when one considers that Holley recommends an in-line fuel pressure gauge be installed ahead of the TB. Available for around $50, this is a modification that we will be trying in the near future. (see future sidebar). Once that is installed the fuel regulator may be adjusted. On the back side of the TB, behind the injectors, is an aluminum cap. Turn the adjustment screw clockwise to increase fuel, and counterclockwise to decrease fuel.
All of this has pointed to the importance of efficient air flow. Enlarged cat-back exhausts and free flowing air filters appear to realize more of the Holley's potential. We noticed some lessening of the richness problem as we 1) cleaned our K&Ns, 2) flipped the cleaner housing lid and 3) replaced worn spark plugs. [For a more thorough discussion of Holley TBI tuning, one should consider a book on their carbs and injection systems available from HP Books.] Finally, advancing your timing may be an option to consider, it having worked well for a few of us.
