Because where an open end wrench might slip off, a line wrench has the extra bits at the end that in effect create a fifth point of contact. Thus vastly reducing the risks of slipping. Especially when dealing with the fittings on fuel, and brake lines...as they tend to be made of a softer metal.

Ohhh okay, you couldn't just slip the other end of a normal wrench over it? (The side thats compltely closed)

Nope, how would you do it? Remember, were not talking about the banjo fitting on top (and on that fitting you should used the closed end)

Ahhh yea.
I didn't look close enough at the pictures.
I was more thinking about fitting the line wrench directly onto the nut, not through the line then over top of the nut lol.
My bad.
Thanks for clearing it up.

-Always disconnect the Battery before starting (its close and you are dealing with fuel!)
-The sensor in the top airlid is an air temerature sensor, not O2.. to avoid confision.
-ALWAYS relieve fuel pressure before removing anything in the fuel system (mentioned)
-Use Line wrenches to avoid the headaches of stripped nuts AND hurt knuckles. (mentioned)

yes I know old... there were no other new threads (google told me so)

my fuel line is deteriorating from behind my intake manifold. Its a 5/16 fuel line that I got from a hard ware store. i don't have the oem beams fuel line as those cost $180 brand new from japan.
I noticed the oem fuel line from top of fuel filter to fuel rail has a rubber wrapping.

When I install new fuel line, should I wrap it with 196 degree electrical tape so it won't deteriorate in the future. Its only been 4,000 miles a 4 months since I installed a new one....

see fuel line from hardware store after 4,000 miles


new line from autozone. hopefully this one will last longer. also whats the difference between fuel line and fuel injection line!! the fuel injection line at autozone had a blue tape lining on inside of rubber line... but I didnt get that because they ran out..

The difference is that regular fuel line is designed for carbureted engines which run very low fuel pressure and the fuel injection hose is stronger and designed for EFI cars which run at much higher fuel pressures.

oh so then the one I just installed will just deteriorate again in a few months...

is this the same or similar on a 7A?

also today while driving my car suddenly shut off. I figured hmm electrical or fuel pump line again. As sure enough it was. The first line lasted 4 days while this one lasted 20 days what's going. Do i have wrong fuel line.



the one I just installed today is an autozone brand. Hopefully it'll last me for well over a few months....???

Is there any sort of maintenance schedule for the fuel filter?
My car is starting to have an issue and I can't tell if it is pump or filter. Would be nice to know if there was some "scheduled maintenance" that I missed on it or if it is supposed to be a lifetime.

Rule of mechanical thumb is trying to change the filters at least once a year at least as far as a regular scheduled maintenance. If our cars were still new it would be after the first 50,000 miles were put on to have it changed or cleaned, however with age comes the chances for debris and rust so its better to clean or change yearly.

Wow really? I have some serious doubts that any of the previous owners have changed it on my car, and for the past 3.5 years I haven't either, only thing I do is run chemical additives and use good fuel.

I assume the repercussions of my actions, or lack thereof, is deposits going into the fuel injections or engine? Which is no bueno
