Gas Tank, Fuel Lines Options

[doit2xs]

Hi, anybody know on the gas tank when using carbs, do you block off the 5/16" line that has the baffle and use the 3/8" line that goes straight through? Do I get a cap to block it off, or just use a piece of fuel line and a bolt?
Thanks, Don

The one with the screen is the suction outlet for the pump.

You can block off the return line but it is actually better if you use it, even with carbs. Keeps the fuel cooler.

Hi, screened port? I did not see a screen? Did you get cap at parts store?

The smaller tube isn't really baffled, but is necked down to a small opening at the top. A short piece of 5/16" fuel hose, a long bolt with the threads cut off and two hose clamps is a good cap to block it off.
If you remove the 3/8 line there is a tube shaped screen inside the tank fitting. Its a good idea to inspect it and get a replacement if its clogged or damaged.

if you look inside your fuel tank with a flashlight you will see a screen/filter in there. thats the one you will use for your carbs. the other one can be capped off. i get my fittings from summit. except for the fuel tank fittings because summit doesnt carry them. this is a -6 cap for the tank fitting. http://www.summitracing.com/parts/AER-FBM3740/

for 15 dollars worth of fittings, i think its alot safer than a bolt and hose clamp.

I used a flashlight and one port has a metal plate with a hole in it, the 5/16" one. And the other is wide open the 3/8" one, and you can see out the filler. But no screen. Do you know where I can get the screen? Thanks

Several places sell the screen. Check out the member vendor section here on 914World.

If you haven't replaced the plastic line in the tunnel you may want to check out Chris Foley's site. You should consider replacing these lines. They are starting to age out and we have had several of our members loose their cars to fires.

He has a nice stainless steel line kit and also sells the filter screen.

And if I didn't say it before.... (IMG:style_emoticons/default/welcome.png)

Gas tank screen. Old vs. New.
I have FI, but the old one would actually stop the flow of gas.

Besides it is the gasket for the fitting, aluminum crush ring on end.

Here is a great example of why this forum is so important. I have my engine out and didn't even think about replacing fuel lines until I read this thread. Thanks guys, I love ya.
