The Aufgeladen Ghia

Oh... There are no hills around here for 50 miles. I live in California central valley. Yes, I have the same concerns as you... Have not finished the install. Have a couple ideas I'm mulling over. I may bend the aluminum shaft in order for the input sock closer to the bottom. Stay tuned.

Do a search on fuel tank baffles. There are several ways of doing it.

It is not necessarily an off-road thing as a lot of us use round tube tanks but some of the tanks do/did also have the baffles in them.

Foam in the tank is/was one way of doing it along with using other things to slow down fluid movement but the way I have seen it done mostly is putting cross plates inside with the bottoms of the plates open to allow fluid movement back and forth. This allows the fuel/liquid to still move around but at a much slower rate of slosh. Road racers and drag racers used to do it in the engine sump also to the pickup didn't start sucking air during launch or hard corners.

A pivoting pickup (usually the oil pickup in the engine) was another way but I am not sure if they are still doing it now days.

Thanks for the reply Ol'fogasaurus!

After some research, I've decided to buy an in-tank corrugated hose to place the pickup sock closer to the bottom of the tank near the original outlet fitting. The original outlet fitting has been replaced with a larger diameter fitting (3/8"). It will instead be used as the return line. A hose will direct the incoming fuel away from the sock. I am scrapping the swirl pot/reservoir idea, and instead installing fuel cell foam to keep the sloshing to a minimum and keep air away from the sock. I think this will be the best method.

Buy high end foam not jegs or house brand. I have a friend that went through hell when his budget fuel cell foam starting coming apart.

I really believe that you do not need a swirl pot or foam. We built a fuel cell for off road buggy to fit in space available using a Subaru fuel sending unit and pump, the sock sits 1/2" from bottom of tank and I have never had an issue even climbing hills or at awkard angles. Also every OEM fuel sending unit that I have seen places the return very close to fuel pickup.
Looking Great

I put mine right in front of the original sender. I just got lucky because the fuel gauge cable goes right through all the stuff. Nothing i had planned! I put it there so the sock would sit in the little "sump" at the bottom of the original tank. So far so good.

I have had momentary dry fuel lines when I had the original flat VW front tank up front in the original location, mostly having problems only when "facing" a sand dune.

This was taken at the Saunders's Lake dune on OR which is about 110'+ up. The first photo is on the way up and the second pix is going across the face at about 80' and going for maybe 100' or so (guess) before dropping down; I have dual carbs. I didn't run out of fuel as I am using a 10 gallon tube tank that sits higher than the engine and I keep no less of half a tank full of fuel in it. I don't know the face angle as it changes due to all the rough/aggressive riding that goes on it all the time but you might get an idea from the first pix.

I still use stock fuel pumps but electric pumps should refill the lines faster but I don't like the idea of "lean out" to the engine. Remember, cameras do flatten out things.

Thanks for all the input guys. I have fabricated a barbed end to go where the sock attaches to the pump. From there, the corrugated hose will extend to the bottom of the tank. I ordered a new sock which will attach to the end of the hose. The foam I ordered... Doesn't give me a warm and fuzzy. I will take Steve's advice and not skimp on the foam. I plan on placing the foam atop the sock keeping air from sloshing around it. Still in the planning phase, and very much appreciate all of your input. I am confident this will work out well.

I'm with Kenric on no foam..... It seems it's more trouble than fix.
You are not going to get into any steep situation with your Ghia and certainly not off road. I think you are over thinking it a little too much.
Just like everyone says the Tee at the bottom of a tank doesn't work.......I say BS....It works and I can prove it with 40,000 miles of all kinds of driving.
You are automatically going to be a little more careful in driving once your tank gets low so if it does happen you will be ready for it. It's easier to drive like a grandma for a while than have to pull a tank and clean the whole system out of melted, eaten foam.
With that extension it will work great......

X2 on rhe cb T tank end.

I also have one and I can't see why it would cause problems...

Mine hasn’t ever given me issues.

Well past the T fitting at this point. You guys have convinced me not to use foam. Will just be certain the sock is near the bottom of the tank near the return. And will point the return in a way not to aerate the fuel (ie; pointing down).

[Clonebug]

I wasn't meaning for you to use the Tee.....Just as an example that everyone says they don't work but they actually do.
My conclusion to asking advice especially on that other site....is to take all the advice and filter it out.....go with what you feel is best.

When you have a 16 yr old kid posting 3200 posts in two years....starting when he was 14.........and pounding out advice on every forum known to man........you just got to ask yourself.......

Build it your way......You are the Mechanic and the Engineer.

Most times every build is a little different and other ways aren't quite right......you can always take the best ideas and make them work for you.

Make sure you wash the sock first !

With all the stuff that is now in fuel and I don't know anything about E-85 a but I just got this off the web:
("E85 is an abbreviation typically referring to an ethanol fuel blend of 85% ethanol fuel and 15% gasoline or other hydrocarbon by volume. In the United States, the exact ratio of fuel ethanol to hydrocarbon may vary according to ASTM 5798 that specifies the allowable ethanol content in E85 as ranging from 51% to 83%. This is due to the lower heating value of neat ethanol making it difficult to crank engines in relatively cold climates without pre-heating air intake, faster cranking, or mixing varying fractions of gasoline according to climate. Cold cranking in cold climates is the primary reason ethanol fuel is blended with any gasoline fraction.")

From another search the info I got told me that foam is not one of the best thing to use around alcohol. I would also check the other stuff that people are using inside of the tank before I got too far along with this.

For what it is worth,

Hello everyone. I present to you... "The Aufgeladen Ghia".

Oh man, I love a dumped ghia on 17s! This was my 62. Yours is a way nicer car though.
