1990 4runner fuel line replacement
I'm not very good at this and my Haynes manual is missing. I see yet another problem with my more-worthless-by-the-day machine: the fuel line is leaking (spewing actually) where it connects at the top of the engine on the passenger side. I'm assuming I will have to replace the line from there down to the fuel filter. Like I said, I know only enough to keep me away from a real mechanic some of the time. Can anyone give any advice on this? Is it something I can do with the usual tools? Is it even something I can do at all, since I don't know what the hell I'm doing? I'm pretty short on money or I'd just take it in. This is only one of about six other serious problems, but I don't think I should operate the thing at all until this is fixed, even if it's a temporary fix just to get it to the shop a few months from now. Thanks for any help.

Can take a pic of the leak and where exactly it is? Or a very detailed description(engine size ??), There is a junction for the fuel line by the frame, accessed thru the front pass wheel well. So you won't be replacing the line to the fuel filter.

There is a flexible high pressure fuel line between the fuel rail and the hard line that goes to the filter.
Your 90 4-runner is probably similar to this 93 FSM:

The engine is a 3.0L. It's the high pressure flex line that's leaking. Right around where it connects to that... "thing" with a 90-degree angle which goes into the engine. How difficult is that to take out? Like I said, I don't have a manual, which is dangerous for me. I have to try this myself if I can, because I'm dead broke and this is my only means of transportation - no buses or anything else out here (rural area).

Ran into this myself where the rubber portion (about 2 feet from the engine) expanded, breaking a metal clamp and allowing the threaded portion of the metal tube to began sliding apart. This caused fuel to leak near the starter.
Looking at the 20 year old fuel line and rusty fuel filter - Does anyone know if the entire fuel line can be replaced with a full tank of fuel? If I disconnect the fuel line at the tank and engine using a catch, does this seem to pose an issue?
Thanks,
Ben
