Craig - hmmm.
Nope -
oil does not "continuously circulate" through the Accusump, but if you have it "on", and there is a significant difference in the pressure it "sees" (i.e from high rpm down to idle), then there would be some
oil going in and out of it, and I guess it would be hot after a while.
I don't use my Accusump for hot restarts when the engine has been sitting for only a few minutes. I only use it for pre-oiling when starting the thing up after it has been put away red hot and left for a couple of days or longer (i.e. all
oil drained down).
After all, production engines (and those without accusumps) survive even cold starts OK, we just like to "baby" our engines!
You don't have to put the valve on the end of the Accusump - you could run some hose to position the valve where you want it, and mount the unit out of harms way. I have heard of units being mounted in the back of a car, with the valve handy for the driver's reach. I suppose at some stage the losses in a long length of hose might reduce it's effect.
What is the " significant" difference in the flow rates manual valve vs electric? I do like the convenience of the electric valve.
Ultimately, if you do end up with a hot accusump positioned where your arm might brush against it, there is nothing to stop you from insulating it in some fashion.
