Fuel tank (continued)


So after the wiring work, i've gotten back to the fuel system.

now that the pump is removed and replaced with a hose,thenextstepistoinstallanin-tankcoolant heater loop. Hot coolant is being looped to reach inside of thetank right near around the fuel
hose, to keep the bio-diesel thin, so it runs easier.Steel hosing is twisted in ovals with an entrance and exit end. So the next step to install it in the tank, was to cut 2 holes on top of the cover, and then carefully solder around the steel lines, creating a seal. the steel line is tie-strapped rightnear the hose to ensure its fixed in the tank as well as staying close to the hose.
Once the engine is in, we will connect coolant hoses to the lines, which will also be bundled into a larger insulated hose with the bio-diesel fuel line, so that the fuel stays thin all the way
through the lines.

i wanted to connect the fuel fitting to the tank but the company gave us the wrong nuts (too small), so were waiting to find more special bolts to connect. (the original bolts are too rusted and damaged)


Venting for the tank is needed so that as fuel level lowers, air is pulled in, so that suction doesn't occur in the tank, which could create problem in not allowing fuel to flow. A diagram shows us that the venting system isn't needed for 'general export' diesel tanks: it just doesn't display any. but we thought it'd be good to have one, especialy since we could with the given venting peice on the gas model tank. I had to figure a way to attach a hose, so that air enters but doesn't escape. i found a filter piece that allows air in one way but not out from the vacuum canister from the trooper. i attached a hose to the venting lines, to the piece,to another house, which i will later have ti-strapped in the most convenient spot under the vehicle.
