i have a 1991 4runner v6 4x4 and it leaks fuel from (what appear's) the top of the gas tank and it only leaks when started. what could it be? fuel return? and is there an access panel on this year? what could have caused it?
thank you. in advance for the answers/supestions.

 

its prolly one of the lines... Mine rotted away right at the top of the tank. You will have to drop the tank to get to it, unless u wanna use a hole saw under the rear pass seat...If u do it that way, just make sure u dont cut the tank...lol

 

Fuel line is probably rusted and ruptured. It's either that or the fuel pump bracket. It has 2 hard lines coming out of the top of the tank that may have a split. Same happend to my 89 pickup. Like $150 from the dealership for the fuel pump bracket (that dont include the actual pump) I couldnt find it at any store.

 

There is an access panel under the passenger-side rear seat which will give you access to one fuel fitting. If you are really, really, lucky, the leak is there. Much more likely is that one of the rubber lines / connections to the fuel pump assembly is hosed (pun intended), and you are looking at dropping the tank to fix.

 

One thing good... yotas got the gas drain plug, makes for a lite tank.

 

i was goofing around on ebay yesterday and saw one for like $36... i hope its an easy/cheap fix cause cash is a little tight..... this is actually my first toyota (besides a camry).... ill post in a couple days and let you know what it was i just wanted to get some thoughts since this is my first yota... thanks again

 

Indeed ebay wudda been cheaper, but I had to drive mine for work. I'm sure if you search you can find a writeup to help with whatever you need. I've found everything I've ever needed and more here.

 

On my rig, it was the hard line on the pump bracket. I went down to the parts store, and got 3 feet 3/8 brake line, pulled the bracket out, drilled the old hard line out and put the tube of 3/8 brake line in, then tack welded it to the bracket, and sealed it up with some jb weld. I think it cost me a grand total of $8 to repair it.

I think someone did a writeup on it here on yt... do some searching, and u should find it.

 

thanks for the tips good idea on the pump bracket...do they sell parts on this forum? im a newb to this forum

Go there and look for the "Yotatech Marketplace" section.

 

I can almost guarantee that it's your rusted out fuel pump bracket. I did mine last year on my pickup. I already had the bed off when painting the frame, so I figured I'd put a new bracket on the tank while I had the easy access. My bracket looked so rusty I thought it would spring a leak at any moment. The bracket is about $140. You will also need a new gasket and 7 or so new bolts to hold the bracket down.
