Hey Guys,
I'm thinking about installing an extra fuel tank into my suburban.
Body is off the frame right now, so installation shouldn't be too bad.
Diagram attached. I've never set up a fuel tank before, so it would be great to hear what you guys think.
There are a couple things that might be less conventional, but hopefully ok:
-Using the stock mechanical fuel pump (235 engine) while adding a return line.
Hoping this will get rid of vapor lock... last summer i could see gas boiling in my filter bowl by the carb.
Stock pump supposedly flows at least 25gallons per hour, seems like that could happen through a 3/16 return line?
235 engine itself not expected to use more than 6gph.
-filler cap on the door step inside cab.
Probably against rules in other states... but I can't think of any way it would be dangerous?
As long as it's a sealed type of cap i think it's safe?
Alternative is to cut a filler hole on the outside of the truck, or run a 3' filler line teeing to original filler on other side.
