just got a quick and easy question for you. Making a 60 gallon fuel (SVO) tank. I have it at 55"L x 23"H. so if I want 60 gallons how deep do I need it to be?
Thanks!
 
Well... 1 gallon = 0.134 cubic feet.... so 60 gallons = 8.04 cubic feet

So, 4.583' (L) x 1.916 (H)' x D = 8.04 cubic feet

.... 8.78SF x "D" = 8.04CF

D = 0.91-feet..... little less than 11-inches

I think that's right..
 
Yup,
60 gal = 13,860 cu in.
This is your target.

55x23 = 1265 sq in you have already
so 13,860/1265 = 10.9565.
Now remember you won't get 100% back out of it, so if you do say 11.25, you'll have 61.61 gal.

Amazing how 1/4" height buys you so much volume when the footptint area is so big
 
wow 11", I was hoping it wouldnt be that deep. oh well, 60 gal is my target capacity and i dont plan on changing

thanks for the math lesson btw, i've been a few years without one

Well as long as you dont look like that pic of Gary Busey you have up i think everything will be alright....



(notice i didnt even attempt the math problem :lol:)

on this same 23"H tank, where is the best source for a fuel gauge/sending unit and what is a good diameter fill hole?

If you dont mind an unusual gauge, I use a company all the time on diesel tanks that does custom gauges/senders on the cheap. You will have a small round didgital gauge though not a needle.

PM me if interested I will email their contact info.
 
Don't forget to add the thickness of the metal to all dim. or you'll come up short.
 
plus pick up tube length will determine actual volume vs useable volume....
 
could i not tie the sending unit into the existing gauge? I dont mind an external gauge at all but my bro-in-laws SVO unit is all tied into the existing dash.
 
You could.. you just need to know the resistance of your gauge (empty and full). and get a sending unit to match. then its a matter of putting a switch between the two sending units
