will this work? bout 40-50 psi on my nitrous system on my bike. reliable as <edit>. internal bypass?

havent ever seen it discussed directly...maybe an obvious reason i dont know about?

 

What exactly is your question? What's that about 40-50 psi on your nitrous system on your bike? To answer your title question, yes, I have been running a Holley Blue for a lift pump for about two years 25K miles with no problems. Fabricated a bracket to use the stock location, adapted stock electrical plug, cut the lines and adapted with rubber hose. A really easy cheap fix.

 

....for the amount of people I've seen walking the pit areas looking for a "spare" holley blue, or parts over the years I really wouldn't consider using one on a truck I actually had to depend on.
