Fuel filler neck
Good morning.
I fitted a new fuel tank (not genuine Volvo), but I'm a bit confused about the filler neck fitment and Google seems to have very few photos showing this in detail. It the last bulge on the tube not meant to butt up against the tank inlet? I'm only guessing but annoyingly didn't check when I took the old one out. P.S. Just been on the phone to Brookhouse where I bought they'd never heard of the problem. The tank can't really move when fitted and I didn't have the neck off and it doesn't appear to be movable anyway. Thanks Henrik

Haynes describes two kinds - earlier and later, with diagrams.
There's a note that the tanks were different and only the later type is now available, so "several modifications may be involved". The later type appears to just have a joint like an exhaust pipe, with a clamp holding the two sections together. I've found it very difficult to secure a leak-proof joint, and it recently started leaking. I stopped it by plastering body filler over the joint. |

Hi Clifford,
I'm pretty sure my one is the later type. And my Haynes manual doesn't cover tank replacements. Did you look at the photo? Do you see the 1-2cm distance missing I am talking about? EDIT: Sorry, I always forget the forum software prefixes the URL field http:// P.P.S. How on earth did you get your fingers in there to put filler around it? Regards, Henrik

Is that first bulge a separate distance piece (like exhausts sometimes have to join two female ends) or part of the pipe from the filler?
It was very hard to see what mine has (fitted before my time, probably original) but it doesn't look like a separate ring. As I often find with exhausts, the clamp even when fully tightened doesn't really pull the ends together to seal the joint. PS. Smallish hands and fingers I suppose. I dolloped a lump of filler with a spatula at the furthest point I could reach, and then smoothed in over the bit at the back with my fingers. I then worked filler into a strip of loosely woven rag and pulled it tight around the whole joint. |

Suppose I'll have to live with only filling the tank up 3/4? Thanks, Henrik

I wonder if the part where it goes through the boot floor is perhaps not aligned properly?
I've had my tank and filler neck off completely to weld up the area around the boot floor, and I had to re-fabricate the hole where the neck goes down to the tank. I managed to get this slightly wrong and now the filler neck sits at an angle into the tank, meaning I get a small leak whenever I fill it to the brim. You are right in thinking it should fit closer into the spout of the tank. There is a rubber seal that should fit tightly in there to prevent the leak I just mentioned. |

Ok, you've prompted to tell the whole story! Last summer, the car when in for welding and rust fixing. Part of this was removing the tank and putting new metal in the boot where the filler tube goes through! The first time I filled up the car, petrol poured everywhere! I though it was just because he hadn't tightened the clamp enough. So, sounds like, he put the hole slightly too high! Thanks, Henrik

My plan is, once summer arrives, to drop the tank and enlarge the hole a fair bit.
You might be able to enlarge it in situ with some curved tin snips. Mine, I left the welds in place as I tend not to grind them back where they are invisible. So I won't be able to cut it without the grinder and potential fireball death. Hence dropping the tank. It may not need much. I reckon in my case I need to shave about 4mm off one side of the hole and it'll slot in nicely. |

It’ll be very difficult to get that clamp in place with the tank and filler neck in the car. I replaced a tank on a car I used to own and put the filter neck on the tank with the clamp in place but only half tightened before putting the whole assembly into the car.

I don't understand why that would be easier. Both parts are completely rigid, it either fits or it doesn't. I'm also mystified by that clamp screw, it's the same one I have, but it is far too long. Thanks Henrik
