• I'd like to have a spare IP to take along on long road trips.  I've heard that an IP will go bad if it's unused for more than a year -- I guess the seals dry out or something.  Is there a good way to store a pump?  Can you keep submerged in diesel fuel?
  
  Thanks for the help

• yes, it will dry out if it just sits there...fill  the pump up completely with diesel fuel and kerosine or some other diesel additive (used to keep the fuel from gelling if it gets really cold)...seal it off with plugs so that nothing will leak out of it ...place into a couple of very large zip lock bags and hold it upright to prevent any leakage...it should last years for you this way providing no diesel fuel leaks out...

• Thanks, where and how exactly do you fill up the pump?

• could u just unplug it and place it in a 5gallon pail full of fuel. then let it sit in there? then you wouldnt really have to worry about the diesel leaking out.

• That's what I was thinking.  But I think the bucket would have to be airtight, otherwise microorganisms can eventually grow in the fuel I think.  Maybe a one gallon buck would work.  For road trips though, I like the fill with fuel, cap, and seal in a zip lock method.  
  
  Still wondering what the best way to completely fill the pump is.
  
  Thanks

• Put fuel with additive  first into the intake part of the pump(where the hose connects to the filter)/plug it up...then put fuel into the outlet hole of the pump/plug it up...or dunk in a pail of fuel and wait for a few minutes...you will still have to plug up the lower orfice and dunk once more to bring it up the the outlet orfice......let it drip dry and place into several jumbo size zip lock bags and keep it from laying on it side.....

• How old are your pumps?  They seem to last a long time although mine will seep a little when it is -30C.

• my pumps are from the mid 80's to 90...at -30C any seal will shrink a little...just keep topping them up from time to time
