I have an 02 ep that I ripped out the tank to and put a 8gal cell in with the biggest inline bosch pump that wont fry my ecu from endyn, and was wondering what was the best 12amp power source?
Could I use the stock pick-up that went to the stock pump, or do I just cut those wires & go from the ignition???

 

I know some people use the altenator. Someone in here has to have some good advice???

 

Use the ecu wire to trigger a bosch relay feeding current from the battery. That way you will never have an issue.

 

I hope I got this right, you take the stock sending pump wire from the ecu & hook up a bosch relay & then into the pump?
Thanks for the help speeddreams!

 

yea...run a 10 or 12 gauge wire...i used 10 on mine...from the battery to the pump, but use a relay that is controlled by the stock pump power wire to power the relay...and put a 30 amp inline fuse on the wire from the pump to the battery...good luck...

Thanks alot, that was very informative.

best way.
or like posted above, us the stock fuel pump power to trigger a relay.

thanks for the good info guys will put this to good use becasue im about to order the pump

 

if you haven't ordered the pump yet make sure u get the high pressure 255lph walbro...if that's the pump u are looking to use...the make 2 different 255's...but both are the same price i believe...i can't remember the part no. offhand...just wanted to share that...

i think they are talking about inline pumps

 

Here's my diagram for 1000 years ago...



That was if you didn't have a factory trigger wire (from an OE ECU) to activate the pump. I normally tell people who are using their factory ECU's now to control the pump to wire the 12V+ side (85 in this diagram) to a constant, then use the FLR (ground) output from the ECU to activate the circuit (86 terminal).
