I just got my Holley 255lph forced indiction fuel pump. I want to put it in and take the airnex(?) pump that came with my Drag kit off. Will this be ok, or do I need to leave the external on? I really hate that one, but I'd hate going lean and blowing my engine worse. Thanks

 

If you're using stock injectors with the DRAG FMU (ie. high fuel pressure) stay with the external. Internals can't hang with high pressures.

EDIT: Just noticed the Hondata 2B in your sig. I assume you're using 440+ injectors then. If that's the case, an internal could be used.

I guess my setup would help:
Hondata 2b
RC 440cc's
TR&D 3"
Carsounds cat
Drag 3
B18C4
LS tranny w/Quaife LSD
Clutchnet stage 2 clutch
Asco lightened flywheel
JG intake
AEM FPR
Had a AEM fuel rail, but it didn't like my JG intake
That's all I can think of right now, intank, external, or both?

If you use the Hondata you will not have to run the external pump, the in-tank 255lph will work fine. That is what I use and I have the same fuel setup as you do.
