Just ordered the HPFP 150 from vulcan and noticed the relay harness is it needed as well?

 

well as you know the pumps them selves are not vehicle specific so they might be selling the pumps and harnesses seperatly.

 

sorry that didn't answer your question yes you need the harness

 

Just got my airdog 2wks ago it came with everything, harness, drawstraw, 25ft of hose, fittings nuts and bolts and brackets,Everything included for 499$ I installed it 2 days ago, I had a couple of small issues that were easily resolved, If I had not e-mailed Mark (Coaltrain Diesel) first I might have installed the draw straw in the wrong place.
So far I'm happy with the install it was plug and play for the most part, my only issue now is my autometer fuel gauge only reads to 15psi, and right now its pinned all the time (LOL)

I thought the Fass came complete with everything, I'm glad I went the AD route, cause its not worth the grief of running around sourcing parts to do an install.
I'm sure even if you dont have a wiring harness, one can be made quite easily with a relay and a few feet of wire,

 

I think the complete systems do... but this is just the HPFP pump filter and seperator. I thought it would having everything though because it was listed for my truck, as in vulcan put the kit together for 00-02 trucks specifically.
