This is mostly for Dan, but I'm asking publicly just in case I'm not the only one wondering this.

The description of the fuel line mod says to mount the fuel filter vertically, I assume somewhere near the alternator as you say it takes advantage of the airflow from the alternator as a source of cooling. My question is, is it actually secured somewhere or do you just have it hanging by the hoses on each end of it?

Know how they always build a better idiot? That's me

I have recently found out that this modification is Illegal in Pennsylvania. Any reputable inspection station will fail you on your annual safety inspection if you have more than 1 foot of rubber fuel line between your gas tank and carb.

So use steel line with just enough rubber to mount the filter.

Growing older is unavoidable but growing up is strictly optional.

It's not secured to anything; the short length of rubber hose (3 to 8 inches) coming up off the fuel pump holds the filter vertically, and the hose coming off the top of the filter keeps it from shaking around.

Interesting about PA's rubber fuel line restriction. Wonder what they do about all the many vehicles that have a great deal more than 1 foot of rubber hose in the system right from the factory!

Sorry dude, but any moron that puts that much hose on a fuel system shouldn't have a drivers license.

They may allow from the factory what they do not allow from owners/shops/aftermarket. It may also be one of those areas that is in the discretion of the inspector, with an implied responsibility to fail any part or situation that isn't in the book or approved/certified/officially kosher.

I believe Virginia has the same law.

That could be. I remember seeing a burned-out mess that used to be a '74 Volvo. That was the first year for CIS mechanical fuel injection on Volvos, and that system used flex lines from the fuel distributor to each injector, and about an 18" section between the fuel filter (mounted near the firewall) to the fuel distributor. Someone had repaired the fuel lines on this particular car with plain ordinary carburetor-type fuel line hose, SAE J30R7. Of course, it could not withstand the high pressure in the fuel injection system, and burst. The lesson is obvious: There's nothing inherently dangerous with large amounts of flex line in a fuel system, but it must be the correct type for the application, and it must be properly installed. The real morons are the ones who don't exercise the small amount of common sense needed.

Type 1 VW's were notorious for burning up. The typical scenario was an older Beetle with an aftermarket fuel filter on the fuel line going into the carburetor.
Now, adding a fuel filter ought to be a good thing, right?
Putting said filter in an easily accessible place should be a no-brainer, right?
Ditto for replacing a mangled tube.

Three problems:
1. Factory fuel hose was metric (5mm, IIRC) - not the most common thing in the US. 1/4" looks close, so ....
2. The hose attached to a press-fit tube in the carburetor body. Add the weight of a full fuel filter bouncing around on a length of hose, let the whole thing age ...
3. The metal fuel line was sometimes replaced with a long rubber hose, passing through the engine tin, with no protection against chafing.

The hose slips off the tube, the tube pulls out of the carb, or the hose wears through. Either way, you now have gasoline spraying around the engine compartment. One little spark, and WHOOF!

All of these situations are easily avoidable.
Think through fuel system repairs and modifications carefully.

For what its worth, I did the fuel line mod around 2000 or so. Still the same hose and connections. No leaks, same hose. I also replace all the soft hoses from the tank to the engine with the fuel injection hose.

If you want to secure it, zip tie the hose to the heater hose bracket on the side of the valve cover.

OK let me clarify my previous statement. You can have more than 1 foot of rubber fuel line, you can not have more than a 1 foot section of rubber fuel line. Rubber fuel line can not be used to replace worn out steel lines. you my only use rubber fuel lines to connect metal lines to fuel tanks, fuel pumps, carbs, and fuel filters.
I know some one (no it wasn't me) that used rubber hose from his fuel tank to the carb of his CJ-5. It failed inspection.
