Heater Fuel Tank continued:
Now that I have a near complete set of measurements it's time to decide on some equipment. Diyvanner had already done the research so I just followed his lead. For the fuel inlet that will go through the side of the van I'll use a
Sea Dog Stainless Steel Angled Hose Deck Fill. Model# 351521. Made for 1-1/2" fuel hose with "Diesel" written on the face plate.
It's currently around $40.
I couldn't find all the dimensions I needed on-line so contacted the company to get these additional two.
I'm assuming that I can place the fuel inlet on the side of the van no higher than the level of the floor.
The fuel inlet outlet end has a 30 degree slope. I doubled checked the side of the van where the inlet would be mounted and and it has a slope from vertical of around 20 degrees. Mounting the inlet so it's face is flush with the side of the van will now give a slope of 10 degrees to the outlet end.
The fuel tank will be made by
Coyote Gear. They make custom built spun aluminum tanks in 5 different diameters. I think a tank with a diameter of either 8" or 10" will be best. To help decide create scaled drawings with each size.
10" tank
8" tank
While the 10" tank would fit OK I didn't like that it would extend below the bottom edge of the van. Also there isn't much room for error around the sides of the tank in case I made a measuring mistake, and it's getting close to the emergency brake cable. So I decided on the 8" tank.
Next decision was on where to place the fuel inlet on the tank. If I put it on the top of the tank it looks like the rubber fuel hose that would connect the fuel inlet to the tank would end up with a negative slope away from the tank.
The tank could be lowered but for simplicity's sake I wanted to use one of the under floor supports as a mounting point.
If I move the fuel tank inlet to where it's 30 degrees from vertical a formed rubber fuel hose with a 45 degree angled bend should fit with just a little extra bending. I'd prefer that the fuel line had more of a slope towards the tank. The tank will probably have to be filled slowly.
So a 8" diameter fuel tank with a fuel inlet 30 degrees from vertical is the type of fuel tank I'm going to order.*
Before placing an order for the fuel tank I'll have to open up the rocker panel so there's absolutely no doubt about what's inside. Since it is custom made tank I won't get a second chance.
NOTE*: I have over simplified the design process for the fuel tank. I actually spent weeks considered other mounting options and worked out a bunch of different fuel inlet angles but I didn't want this post to drag on forever. While writing up the descriptions of the different things I do on this RV build I'm never quite sure where informative stops and plain old boring begins. At least I hope it's informative.
