Filling up using modern gas pumps

[67_Eldo]

The hip new thing in filling gas tanks these days is the capless fuel filler. Alas, since the vast majority of fuel-filler customers are driving cars less than 38 years old, no manufacturer is rushing to accommodate ancient Cadillacs.

Stant makes an InStant (ha ha) Fuel Cap that can be retrofitted to a few older non-West-Coast cars. You can look on Amazon or you can go directly to Stant.

If your local auto-parts dealer would allow you to look at one in person, it may fit whatever you've got. Then, not only would the pump shut off correctly but you'd also never have to worry about losing a gas cap.

I'm not endorsing this: I pretty much know to put the pump handle into the Eldorado's filler tube, pull the handle, and wait for 30 minutes. But if one of you wants to experiment ...

While I was thinking about this issue, I went to Advance Auto Parts and bought a Capless Gas Tank Funnel (from FloTool) for $2.

We'll see if the additional diameter of the funnel's top affects how the pump's shutoff mechanism works.

When I get my car back.

Jeez, folks, look at your fuel gauge and calculate how much the tank needs. You know your capacity - right? I hope so. Half of a 26 gallon tank is 13 gals.  1/4 tank needs 19 & 1/2 gal.

Do the math.

And wrap the towel around the base of the pump nozzle.

Putting in $10 only gets me about 1.1 gals of 110 octane.

Assuming you have a working, accurate gas gauge.

Curious to hear if that funnel thing makes a difference.  I suppose it depends on how many bends and twists there are.   Maybe it can narrow down and redirect the flow so it goes down easier?    When did they start doing the large filler vent lines running parallel to the filler?

I would if my fuel gauge wasn't out of whack. I think it might be something with the ground wire. For example, I tried filling the car with the key turned on to accessory. The needle went to 3/4 and then gas started splashing out.

But I thought all these cars were 100% authentic and in perfect working order?
