I set off trying to plan out everything that needed to happen for a full backhalf of the truck. First things first was my original goals. They have not changed over the years but the concept of how to get it done has. First thing I did was sit down with all of the gear for the different uses of the truck and figure out exactly how we used it and where it went. For long family camping expeditions we would utilize dry bags on the roof. That was a great idea and worked very well. Sleeping bags, pads, pillows, etc... went in those so we could fit the big cooler in the back. I figured if I had enough space for all that gear fitting anything else would fine.
I also had wasted space with my fuel cell, and did not like how I utilized the circle track sizing. It was the worst for space saving efficiency with my setup. Having known then what I know now I would have built some things different back then. Primarily, I would have built an entire platform above the cell for storage. I also would have lowered my under-the-bed storage container about 4 inches and sunk the cell into the floor. I also had my jack under the bed. Both of those things were so high up they only got hit once. Sacrificing that clearance would have gone almost unnoticed and gained a crapload of space inside. With that said I would never run a non-bladder cell so it was kind of a deal of learning what I did wrong as far as space planning goes as there weren't a ton of options for sizes within my budget back then.
Fuel system stuff:
I was now on another walbro pump. I was going to have to redo the fuel system anyways so it was time to step up to a better pump and fuel system. I could make some gains here. I had setup the LS with Fuel Lab components (Reg, prefilter, and filter), which so far I like, and already knew back then where I was headed with the pump.
The vent was going to stay the same as I had that problem solved.
I needed a fuel shutoff that was fairly easy to gain access to.
Pickups. I had used the walbro pickups (one in each corner) for the entire life of the truck until the vent problem. I took them out to potentially eliminate another theory that Fuel Safe had. They were thinking that if the cell did get overpressurized, that pressure closed the pickups. Which then caused immediate cavitation at the pump head. Supposedly this comes from experience in one of their cells. Anyways I ran the last season with just a flop tube I made up and it was fine as long as I kept fuel in it.
Hydramat: Its 15 micron and that is a problem. Its cool as hell but the restriction is an issue. With my little motor it would probably do fine but I'm concerned with pump life for any pump flow having a prefilter like that. My flame suit is on.
I like the in tank pumps, and the surge tank tech is kicking ass right now. But I like external pumps more to be able to change them out and diagnose stuff in the middle of nowhere without having to break open a hot fuel cell. If you've ever had your arms inside a fuel cell when its at 100 degrees you only get about 10 seconds of working time before your skin starts to scream uncle.
So the plan was a custom cell. I wanted a tall cell with the bottom split in two sections and a pickup on each side directly out the bottom. Gravity feeding to a Y, into my prefilter, into the pump. The prefilter tank size and gravity feed not relying on a siphon I think is a decent idea.
That's all for now. More stuff coming tomorrow.
