Fuel leak....with pictures

Recommended Posts

Hello everybody. Well after 2 weeks my esprit has started to mark its teritory on the drive with a pool of fuel. Ive searched the forum and got some handy tips, but thought i would post the symptoms for the leak to see if anyone could pin point an order of what to check

The leak is comming from the drivers side (rhd car) just in front of the rear whee. Ive taken a look under the car and it seems to be coming from a 3" diameter hole in the cars floor. Also coming from this hole was a 2" ball of white material which i have no ide what is it

Heres the picutures and any help appreciated

have a good day

Mine did the same thing.

I had a few choices.

Replace with steel tank,

Replace with alloy tank,

weld/ braze in repair to existing tank,

Use tank sealer.

I went for the latter, from Frost's. It's a lengthy process , or it was in the cold weather. You have to remove the fuel, so that's best to run the car to the point where you think it's going to not get you home.

Use the blanking plug on the bottom of the tank to drain out the remaining few gallons (you need another car that can run on the same fuel for ease).

Undo the rubber hose that couples the tank to the balance pipe, and drain the petrol that leaks from that as well.

Jack the car up on that side (then nothing will come from the other tank).

Undo lots of wiring, hoses, fill pipes, breathers etc above the tank. Remove the ply wood that secures the tank.

Undo the bolt from the engine bay that secures through the chassis into the tank.

Use all your hand and those of a friend to remove the tank, moving things out of the way.

To chemically seal the tank I had to wash it with detergent.

Wire brush it.

wash it with specialist detergent.

Let it dry.

pour in the paint/ sealer.

swirl it around.

Let it dry (supposed to be approx 48 hours, but takes a lot longer in the winter as you can't leave it outside to get a good draught to remove the solvent fumes).

Paint the outside.

Let it dry.

Re-fit.

I hind sight, there's a lot to be said for a replacement tank.

The 3inch hole is how you can get to the tank drain plug. The white stuff? I have no idea what that is.

Yep sounds like leaky fuel tanks. Could be a corroded balance pipe between the tanks too, I think it was Mark Blanchard who had this on his. If it's the balance pipe not too bad, but I'm afraid if it's a new tank then sorry to say it's a common problem and a right pain to fit a new one.

Last month I've coated mine. I started this project in october, I hope to be on the road in march. :)

If you have the possibility to remove the engine than do it. It will save you a lot of time and headache.

The coating works fine. only needs time to complete. Stir the coating properly before applying.

Just take your time to do this job. It's not a rush job what can be done in 2 days. :)

Read teh instructions on the LEF page: http://www.lotusespritworld.com/EGuides/EM...nk_Removal.html

This is also the moment for doing other "upgrades"

Good luck.

Peter.

How do i see the balance pipe, is it in the engine bay, or do i get to it by looking from under the car?

Sacha,

I think I had to remove the shit shield, sorry, undertray to get a good look at mine. It's the big plastic tray that's held on by about half a dozen bolts. I reversed mine up on to a couple of ramps.

If your car is a very low one you might have trouble with the front valance scraping on the ground.

You could jack up the rear at each side and put it on axle stands to let you underneath.

Or if some kind soul would let you use a proper ramp for an hour.....

As I can't see which model you've got, it could be a big under-tray as Alan said, or if it's G body car you should be able to see it anyway. Steel pipe approx 1/2 inch in diameter runs through the chassis in the bottom front area of the engine compartment, identifiable by having a rubber pipe (S shaped)come from near the base of the fuel tank attached.

If it is the tanks and you don't want to attempt replacing them yourself, give Geoff a ring at Esprit Engineering. He's replaced loads of tanks on Stevens Esprits and is some what of an expert.

Good luck.
