16 gallon tank sending unit experiment in progress.

installed a larger tank and installed stock sending unit years ago. shows empty with 8 gal. still in tank, duh. so now i took a new larger tank and measured to bottom, about 10".
see pic of stock sending unit at about 7" at empty.
Bent rod till it extends to 9".
next few days i will fill tank and siphon out 2.5 gallon on time and register gauge readings. has to be closer than previous set up.

Bob--I'd be interested in how this works out.

That should give you a better indication of Empty. But of course it will instead read Full for a while before it ever starts to drop. Much less of a problem.

However, one thing you will notice is the gauge will be a lot less linear in its fuel measurement. Because of the angle of the float relative to the pivot point, it will swing through a progressively wider arc the lower the fuel is. So, for example, you might get 100 miles with the gauge stuck at Full, 100 miles from Full to 1/2, 25 miles from 1/2 to 1/4, and 12 miles from 1/4 to Empty. You'll have to do your tests to find out the specifics.

Shame we can't fit a reserve switch like my old '57 Bug had!

How did the tank install go? Any mods neeed. Did the Carpet go back on and cover the tank ok. This is next on my list.
The Madness never ends.

Marty---more like insanity, isn't it?

I still think the the type 3 sender is a better choise.

Barry, is this it? Does many mods have to be done?

i knew there would be some einsteins out there.
I had 8 units of Physics in college and i remember reading on the toilet wall: ma=ad
mass of the ass = angle of the dangle

i will continue on this thread maybe in the next few days when i have time to fill up and start siphoning(whick really sux)

And you are going to use a hand siphon - RIGHT? No sucking on the tube stuff here! I've had some stupid close calls over the years. Be safe for $10.00!

I sucked on the hose one time when I was a teenager.

The belching afterward was awful.

Hey Bob, suck on this!

(Sorry,,, I just couldn't resist.)

ernie, normally i would be offended, except for vince..
but since u are a real marine(served on a navy ship) i will let this transgression go and wait till bugorama for payback.

As I recall the Complete Formula is: PP=MA*HM/AD

PP = Power of the Punch
MA = Mass of the Ass
AD = Angle of the Dangle
HM = Heat of the Meat


My memory is as great as it always was, but at my age, my recall suffers.

My memory is absolutely flawless! Somehow, the actual events seem to have been re-arranged over time. I'm sure they just recorded it all inacurately in the first place. Did I mention I'm also delusional?

You didn't have to, David. It's ok. We understand ;-)

Yes Marty,, That's the one I was thinking of Even if you have to shorten it's case to fit in the tank.

It still would be a better set up , And you wouldnt have a float wearing the the thing out so much from its constant bounce while the car is in motion .

I have been thinking about a mechanial verson like it wth a cable that twist a needle composed of a Briggs and Stration brass doe nut float and a slightly twisted dipstick. In design you can likely ajust it to perfection.

Only probem is finding a float thats just the right size to do it and fit threw the tank hole.
