Finally got my exa-pump and was wondering if I can still use the pump failure warning setup with the new pump? Do I just hook up the pump in place of the sts pump or do I just run the wires to an ignition source and have it run constant?

 

just replace the sts unit.... but i run mine with 12v all the time.....

 

Leave the hoobs switch by the pump connected as it has nothing to do with running the pump but will warn you if the pump is not working properly and oil is backing up behind the pump.
You can run the pump on the STS hoobs switch by the intake or run it direct. The STS wiring can be set to run the pump on high speed all the time if you modify it.
Make sure the pump can handle reduced voltage. The design of the EXA Pump may not like variable voltage. Also the EXA pump is not reversible AFAIK. If so make sure you wire it correctly and that the flow through the pump is as directed on the pump. The pump is supposed to be very quiet so I would run it on a full 12V all the time if it was me.
Looks like a nice product, good luck with it!

 

Ok, Thanks for the help.

 

i bought this turbo exa-pump as well for my turbo set up.. what is a good scavenge pump alarm that can be used? is it hard to wire in?

 

It is not hard to wire in an alarm for your scavenge pump. I have STS parts so I am not sure where you can get similar parts.

STS puts in a brass T before the pump (from the turbo outlet) with a HOOBS switch set to 3 lbs (of oil back pressure in this case) to indicate a pump failure or line blockage. The switch closes at 3 lbs and is used to complete the ground from the alarm. You put the 12v rated alarm in the cab and wire it to an ignition switched 12v source. Run the ground from the alarm to one side of the HOOBS switch and the other side of the HOOBS to a chassis ground.

When oil pressure builds up to 3# psi behind the pump the alarm will go off to signal you to the potential problem. Mine goes off under WOT boost from time to time when it is cold so I know to back off. I think my pump is getting old and worn out. I have a new higher capacity one to put in when I get the parts I need sorted out.

 

I know this is real old but I just picked up an exa-pump and have a question. The flow on the exa-pump is reverse in relation to the sts pump. Can it be reversed or if not what have you sts truck guys done ?
