HI all,
Yesterday my helper ran our international 4700 box truck out of fuel (or at least low enough to stall the engine out....DT466).
We brought fuel to the truck and filled each tank equally (about 30 gallons total between the 2 tanks).
I told my helper to never let the tanks get below 1/2 again.
Well, today, my helper called me and said the truck was out of fuel again!
He said it was not his fault because the gauge read full and visual confirmation of the larger passenger side fuel tank revealed that it was still nearly full.
I asked him to look inside the drivers side tank and he reported (to his surprise) the that tank was empty.
We brought him 30 gallons of fuel (put into the empty smaller driver side fuel tank since the other tank was still nearly full, re primed and got the engine running normally again.
We looked inside the cab and there were no switches to switch between the fuel tanks.....the truck had always drawn fuel from both thanks yet when we looked under the truck we did not see any fuel lines under the tanks connecting them together (all the fuel lines are located on the tops of the 2 tanks....one passenger side (larger one with fuel sender wiring) and the smaller drivers side tank).
Upon further thinking, if the truck tanks were connected on the bottoms 1 leak would empty both tanks on the ground so it makes sense to connect the 2 tanks at the top somehow.
So how does one re establish a "link" between the 2 tanks ?....I assume some how the "siphon effect" was somehow disturbed when the truck ran out of fuel the first time?
I just hope until I can get this working right the truck keeps on running even if just on the drivers side small tank (I did put (3) 6 gallon fuel cans and (2) 2.5 gallon fuel cans in the box of the box truck filled with fuel just in case.
Thanks in advance for any and all help.
