Plastic tank fitting II
Hi All,
In a previous thread
http://www.locostbuilders.co.uk/viewthread.php?tid=33011
I learned that fuel tanks need 2-4 pipes.
I want to replace my damaged ally sheet tank for this plastic tank:
http://www.nfauto.co.uk/fuel_tanks.htm
I don't know the exact setup I need to use. Delivery to Spain will be expensive so I would like to get all the bits I need from these guys in one
go.
I've taken a few pics of my current setup, it would be fantastic if you could take a look at them and advise what to order.
The engine is a carbed Fireblade.
Areas of concern:
-Fixings: by looking at the pics of the plastic tank, can you tell the way you are supposed to fasten it to the car?
-My current tank seems to have one outlet and nothing else (no breather) without a vented fuel cap.
-I don't seem to have a return pipe in the tank, I don't know where to look for it in the engine (to see where it goes).
-My outlet hose is a 8mm, I suppose I should order a 8mm banjo assembly to replace the 10mm that comes fitted in the plastic tank.
-My current tank has a cap but the plastic one doesn't. I'd like to put one of these inlet things (I'm ashamed of my English), the kind
you attach to the rear and has a cap with a key lock. What's the name for those and where can I get one, together with the pipe to connect it to
the tank?
-I'm not sure wether my current setup looks right for a carbed Fireblade or I should be looking into connecting stuff in a different way. The car
has been working great but Terry says "if you recycle the airated fuel you can get fuel starvation symptoms" and I seem to remember noticing
something like that (just very slight) in certain conditions (especifically when going fast and restoring gas, i.e. on a hoghway, at the end of a
downhill, when you start to apply gas again gently).
Thanks for any input, guys.
Cheers,
Alex

10-11 = the scary view I got the other day when I returned from a long outing: tank resting on the live axle, with its two fixings broken.

Do you actually need to buy a new tank? Especially as what you have now does work almost OK, apart from falling on the axle that is!
You could use a couple of steel straps over the tank to fix it securely, as seen in the Locost book. Wouldn't be too hard to set up.
All you would then need is a vented filler cap, or a tank breather (although you'd have to drill holes for that - the vented cap would be
easiest).
rgds,
David

I have always been concerned about my setup because of safety in the event of a colision as the car can catch fire.
So when I saw my current tank has broke I thought that's a good reason for replacing it with something less likely to spread the fuel everywhere
If I get to the conclusion that fitting a plastic tank goes beyond my skills, I'll do as you advise
Cheers,
Alex

Looking at your pictures I would think it unlikely that the plastic tank that you are proposing to fit will go straight into your chassis.
I had one of these tanks on loan to me from GTS to see if it would fit in my chassis. I decided that it was not an easy thing to fit due to its shape
and size. I eventually opted for a custom made alloy tank.
If you do decide to fit the plastic tank you are going to have to make up some retaining straps anyway as they come with no mounting holes or
brackets.
I would have thought that a good quality adhedive (possibly epoxy) on your existing mounts and a couple of padded, metal straps over your alloy tank
would be perfectly satisfactory, less work and considerably cheaper.
Experience is what you get when you don't get what you want!!!

The NF auto ones look particularly good, but i'm not sure how true the above is, anybody?

Now that you mention it, the tank looks too short and deep (long), no?? Fortunately they give measurements so I can check. Thanks for that, I
would've ordered without checking it first!
> I decided that it was not an easy thing to fit due to its shape and size.
It's strange because they say "Our new Rotor-moulded fuel tanks are a great solution for most kits especially Sevens", it looks they
designed it with Seven type cars in mind but then they didn't 
> If you do decide to fit the plastic tank you are going to have to make up some retaining straps anyway as they come with no mounting holes or

The claim to have solved this more or less: "Both including 2 stainless steel strips for you to make your own cradle straps.".
> I would have thought that a good quality adhedive (possibly epoxy) on your existing mounts and a couple of padded, metal straps over your alloy

I won't spend a lot of money for getting a plastic tank I finally CAN'T fit because of size or whatever Your / David's proposed
option is starting to look more and more realistic.
One thing I'm going to do is routing the electrics in a different way (away, basically), I now have wires along the tank (between the tank and
the rear body panel), fixed with insulating tape I think you can see them in some of the pics.
Thanks a lot, very helpful guys.
