Petrol Leaking From Around Top Of Of Tank?

[skylinetas]

I had not driven my car in about 6 Months, Petrol tank was almost empty.

Took it to the servo just down the road put $50.00 bucks premo in it and drove home.

Put it in my driveway and left it idleing for about 10 minutes while I cleaned some stuff out of it.

It was pretty cold outside and a tiny bit of water on the end of the muffler so it was steaming off.

I looked under the car and just under the petrol tank there was 3 puddles of what smelled to be petrol, mixed with a bit of dust and dirt.

I could see it had leaked from the somewhere on the top of the petrol tank. There is like a little ledge

near the top of the petrol tank and it seemed to be leaking off that ledge, In the back Left corner, Back Right, and In about the center at the front of the tank. There is kind of drain holes in the ledge too, one on each corner. They were leaking in and around those little holes, and near the little rubber peice.

I have never noticed this before, Does anyone know why?

I take absolutely no responsibility for this. But can you test if what has dropped is petrol?

Test is using the way that you think best (of course, make sure you don't do anything illegal or dangerous)

You didn't say what car, but if it's an r33, or an r ugly poo, take the inspection plate off in the boot and have a look. that's where petrol would normally leak from (unless if you've got a hole in your tank somewhere else.

if its leaking from the top then its the rubber O ring where the access hole is at the top of the tank. easy fix.

otherwise its going to be perished fuel lines.. also at the top of the tank

simon, I agree with you mate. That's why I was asking him to check the cap.

there's another option on the ugly poos. the r33s have plastic tanks so they won't rust, but the ugly poos have metal tanks. Could very well be a rusted tank somewhere.

More likely to be the tank seal though, or perished line

Its definately Petrol!

I got under the car and could trace it back to dripping off one of the lines.

I couldnt get back far enough to see wether it was the connection, or the line itself.

Is the inspection plate under the spare tyre? Does it look onto the fuel lines or where they connect to the top of the tank?

its an R32 not an R dirty pee

ah ok. On the ugly poos, have a look under the boot carpet. you'll see this squarish plate with 4 bolts on it.

look on the right hand side of the boot from memory (not under thetyre)

Once you undo that, you'll be able to tell if it's the tank seal or one of the lines. The r33 has special lines (not standard line with clamp - you know those self clamp ones). the ugly poos have standard lines with clamps (from memory). if they're split/perished, just replace it.

Fuel Line Split, Thanks for your help.

[MANWHORE]

no worries. that's lucky, coz the hoses are easy to get and cheap. I hope you replaced them both (just for safety).

on the later models, you have to get those special expensive nissan ones with the funky built in clip.
