so it's time to unvail the next project. This project is actually version 3.0 of an on-going issue.
What is it? a new fuel cell/gas tank. Having plenty of time to think everything out about my truck not running, re-evaluating all the symptoms etc. I began thinking that the motor and sensors have all checked out, but the truck was acting as it not getting fuel. Thus realizing that it was creating a vapor lock situation in the fuel system.
So with everything in the bed already configured in a way not condusive with moving the current fuel cell up into the bed, I have built (in progress of building) a new gas tank.
The aftermarket tank I currently have can not be retro-fitted into the bed nor can I relocate it under the truck in order to make the changes needed to eliminate the current issues.
Those issues being #1-the tank being located so far back on the truck or away from the fuel rail #2- the aftermarket rail mounted fuel pump is not lower than the bottom of the fuel cell nor will I be able to properly mount it in such a way.
The gas tank needs to be closer to the engine compartment, mounted high enough on the chassis that will allow gravity to feed the fuel pump yet out of the way of exisiting fixtures and systems already in place.
This is solution I have devised;
I have already test fitted this mock tank in location and it fits nicely and is very inconspicous behind the tire carrier. In this location many people have made fuel cells work with other trucks so the position should work nicely in feeding the fuel system.
The plan is to actually place a line boss directly in the center of the floor and have the fuel line ran from under the tank, thus providing plenty of gravity feed to the fuel pump and then onto the fuel rail. Currently the fuel pump is not below the fuel tank and if you have every tried to syphon a fish tank you know you have to keep the recieving bucket below the aquireum level for proper water flow...this is not what I currently have on the truck.
I have already begun the tank construction, using 16 gauge metal. Once I have the welding complete and visually inspected, I will fill with water to find any pin holes or other potiential flaws. Afterwards I will seal with gas tank sealant and test a second time.
here are some additional mock up & progress photos.
the flat piece of metal at the angled side was a temporary brace used to keep
things square until the body was tack welded in place, since been removed
Estimated volume of the tank is right at 17 gallons which I'll be loosing 4 gallons from the plastic tank I have but won't loose much from the factory tank. I'll also gain back all departure angle lost with the other tank as well as plenty of room for the 4 link I still plan to install for my rear suspension if I ever regain the finances to finish.
I'll have updated photos as progress is made.
