Version 1.0:

3/4 PVC coupler turned down to 1.25" OD (except for lip on end) 1.625" OD radiator hose (ID of fuel filler neck) test nozzle: green tie-wrap is location of conical stop on nozzles.



1.0 coupler inside hose:



Insertion of hose:

How to get hose into filler neck.



Fuel filler 1.1:

3/4" PVC pipe into coupler. 7/8" drill down 3/4" pipe.
Hole in bottom for auto shutoff feature in nozzle.
(the 13/16" nozzle should just fit down the 3/4" PVC pipe, but I was just making sure)



1.1 anti-siphon:

Safety wire on end of pipe for theft prevention.
Pieces of pipe on bottom end for support.



Fuel Filler 1.1 Installed:

Fuel filler fix to prevent reguritation effect for 64 Valiant. (wire loop is to remove it while testing fit).




Just filled tank, so it isn't fully tested yet (I was testing the pipe against real nozzles, not my plastic model) so I think it should work.....

An interesting fix you have there.

I have found that holding the heal of the pump nozzle up, and the curved portion of the nozzle against the top of the filler pipe that there is little or no back wash. This position keeps the fuel flowing into fuel, and not vented air, triggering a quicker automatic shut off.

Ps.

Emsvitil: Hope that wire is non sparking material such as copper, and not steel…

One more burning question:
Should one be concerned about a possible static electricity discharge from that plastic & rubber insert?

I have seen postings at filling stations about not filling plastic gas cans while they are sitting in or on a pick up bed. That plastic cans need to be placed on the ground before filling.

Looks like a cool idea for something definately worth doing on the earlier cars.
Most gas stations in town have a SNP running the pumps...luckily my local
Costco has a couple of people who must have classics, because they can put the hose under the nozzle to do the same thing described, and it fills without holding, and clicks of right about 7/8's of a tank.


I like it.

-D.idiot

Forgot to mention the results the previous time I filled up...........
(just filled today, and remembered this thread)


It's better, no big splash now.



There's a very slight dribble as you put the gas in.

Nozzle does click off without the splash back.


But it looks like you have to fill slow.

If you try to fill fast (nozzle clicks off fine, without splashback), the fuel level is slightly higher than the lower part of the fill tube and it makes a mess when you take the nozzle out.


So this fix may just work if I figure out a filling technique......

Recent post reminded me that I have a fix for the dribble.............

I made a rubber gasket from an old inner tube that will seal the nozzle against the plastic PVC...

And you have to fill slow...

"Must fill slowly" indicates insufficient air egress.

Too many people who were born on third base actually believe they've hit a triple.

By slow, I mean the lowest level on the holding mechanism.


It will go in fast, but you risk a big splash when you take the nozzle out.
