I mounted mine up on the driver's side of my intake manifold where the EVAP solenoid goes in stock form. It looks factory. :engarde: :devil:

Here's a pic...it's above the first two coils.

cablebandit 10-23-2007 10:19 AM

me... mine failed and had to buy a new one. Now my eboost 2 trips a relay and turns on my 2nd pump

Speed has them. I use a manual switch, you just can't forget to turn it on!

drag only car? Return system? What size lines?
I wanted to do the same thing but with the small lines I'm using I was worried about heating the fuel too much and running into problems street driving.
