I have a dual tank setup on my motor home and recently it has issues, vapor locking on a really hot day. it was in the 100's so it was pushing the limits and was towing 4500 ish pounds.
So i want to help this problem by adding a small pusher electric fuel pump back by the tanks but not sure where or how the system switches between tanks?:redneck:
When i switch from Aux to Main not only does the sender wire to the gauge change the source for gauge level it also switches the pump source. How and where?
by searching the lines that i can see... my guess is on top of the aux tank as that is where the feeder line for the filter and suppluy to the Block mounted pump comes from.There appears to be another feeder line from the main tank over to the top of the aux tank also.
Anyone know for sure how this system works both electrically and plumbing wise?
i hate to drop a tank to just find out.
im assuming i could just plum a stand alone 3 psi pusher right before the first filter and be done with it?
