Post subject:  Fuel tank question
Hi All


I am now a proud owner of a 78 clubman 998 that is in need of a bit of TLC (pic in my next post when i get organised).

It has been sitting in a Perth garage for about a year and i have taken the fuel tank out to drain and clean it (soooo much crap in there).

I have not been able to get anything through the pipe that connects to the fuel line (have tried blowing though it and sucking on it to no avail).

Could the pipe be blocked or does it require a lot of pressure to suck the fuel through??

Any thoughts would be most appreciated as i am rather new to the whole mechanics game.

IIRC when I pulled my fuel line off the tank, fuel started p*ssing everywhere... so i think it could have something stuck in there :evil:

You could use a small screwdriver and poke it through but be careful that you don't go to far through as there is a plastic filter on the in side of the tank.

I drained the tank as thoroughly as i could beforehand.

I have tried with a screwdriver (and wire) also.......But i opened the float....errrm...thingy on the side of the tank and i can see that the pipe is at least 20cm long and bends slightly, which dosn't help my screwdriver poking ways.

And the float thingy cover is too small for me to get access or see the end of the pipe :(

The best tool for cleaning a pipe with a bend is the inner from an old speedo cable. (sometimes you need to put a piece into a drill to spin it clean)

I say poke through it with a thick wire or coat hanger, dump out the filter and give it the POR-15 gas tank sealer treatment. That little filter is just another thing to clog with rust, varnish and junk that comes off of your tank. POR will keep your tank clean as it will eliminate the rust that builds up and flakes off of the interior of the tank, and you can rely on a good quality glass filter up near the carbs to catch any debris. If you did the POR treatment, you would have to take off that filter anyhow as it would clog with the POR material.

I took this approach 5 years ago on both tanks and have never had any problems. I just change my glass filter element every 2 years and it's good to go.

I would totaly agree...but the Glass Fuel Filter can actuatly be clean..Just unto the two metal peices on each end and clean it .
I would also put the filter before the Fuel Pump as you don't want the Fuel Pump getting clogging up first

I would put a decent size filter before the pump- crud going through them doesn't help their valves. Mine is a Ford EA one, (steel can) it's pretty big. I wouldn't use a glass filter down there, a rock could break it.
I also have a glass Purolator filter before the Dellorto but it's probably not needed now.

Throw half an ice cream container of road base (the large blue crushed rock) into the tank with water and slosh around.

The stones hone the inside of the tank and remove rust, crud just about everything, then empty and rinse. Blow it out and inspect. It should look like clean metal! if not do it anain you'll get the hang of it.

These rocks will not crumble so only use them. Then you can POR or what ever. Me I'd just leave it as honed. You know it's the water and sh&t it the air that causes the crap build up in the tanks.

Thanks for all the ideas. I have a few things to try out this weekend now :)
