Fuel Tank

[fx48_eh64]

Hi guys,
Im new to the forum,
Have just acquired an FC Ute, And from what I have seen on here fuel tanks are a bit thin on the ground..
Mine has a few rust holes  top and bottom and is basically rattling from all the rust inside it.

Is there a tank from another model car that fits easily? I was even thinking a sedan style tank with a spare wheel well in it. then a lift up panel in the floor to access it

does anyone have any ideas?

So im assuming its a 40 litre tank and not a 30 then ?

All i remeber being told it was a 40 not a standard 30.
Im a sheetmetal worker for a reason..

Standard wagon tank is 9 1/2 gallons US which is approx. 36 litres.

Ill measure it and give you a litre capacity would be easier.. :D

ok another question...
Measuring up a VN commodore tank today,
I reckon I can get it to fit, but will it affect the value of the car if I use  it?
it wont hang down any lower than a drop tank would   ie  it would stay higher than the leaf spring curve line
I need to repair the floor area around the tank anyway so cutting it out and modding it is no big drama

Quite a few people have used Commodore tanks in modifieds as they fit easily and supply fuel the way a modern V8 or V6 wants it.
If you wan to run the original grey or a red six then you would need to modify the tank to run a simple vacuum fed pick up or change the engine fuel system to accept a pressure fed supply.

thanks ken for the feedback,

Simple red motor and Trimatic so yea tank will be modified to suit

working on replacing the chassis kink in front of the rear springs at present but just run oout of mig gas, don't ya hate that  :)

Has anyone made a new tank, adhering to the road clearance 200mm rule or is it different for a fuel tank? What's a safe but deepest droptank, using original configulation, that works, for a car lowered a few inches? I was thinking straight gas so also thought of dedicated gas with a donut tank. Does anyone know a rough guesstimate of how low from the existing boot floor base that one can go, using a standard leaf spring but a vs Ute Commodore shortened diff? I'm asking too much hey. Id like to make the decision now so I can at least get the tank chosen. I won't be running an efi engine just a sbc.

As most readers know ,I have an old FC van running a standard tank and a small red motor . The issue is that if you want to use the spare wheel compartment then you have a standard rim and tyre in there and have all sorts of problems if your towing a trailer and get a flat . If you use a bigger tank you can fill your spare tyre compartment with a bigger tank but the fuel filler pipe angle gets ugly. In one of my Vauxhalls I run a FC sedan tank with a VP commodore sender unit with the float wire bent to suit and the fuel pump removed and the pipe blocked off and pick up is through the return pipe with a external fuel pump on the line with a large steel fuel filter between the tank and the pump to reduce air lock [no swirl pot in a FC tank]. And run a V6 so don't understand the fuel pump issue. Cheers Haydn

I designed and had a mate build my own fuel tank.
It runs all the VN gear I.e. In-tank primer pump, sender etc.
I have modified the rear floor to fit the tank in. It is narrow enough to allow the exhaust to pass up either side between the tank and the rear springs.
Reading the rules the tank must not protrude below the imaginary line from where the rear tyre meet the pavement to the lowest part of the rear body.

Thanks. Still haven't figured out what I'll do.

[hsv-001]

You could give me a call or message as I have fitted other tanks , internal pumps ,external on line ,custom and also have an old dented but solid original ute , van and wagon tank here . Haydn

This is prob what I'll end up doing. Dump either side through the springs to the outside.

[hsv-001]

I guess most owners a just driving these for show, but it's no coincidence that nearly every FE and FC that I have owned [and I have owned dozens]has had a dent in the tank . Like I said ,a downward slope on the filler pipe tends to ensure that the tank is kept low . And your sender unit and or your gauge will need modifying . Cheers Haydn

F@&k being a trailer Queen. I want to drive mine

FCV08 do you know what pressure the vn primer pump operates at? They were low pressure until 2 pumps were run after series 2 vn. Did you run a regulator or just the normal pump on the engine if it is carbed? If anyone has a vn book there, can you look up the fuel pressure for me on the series 1. Thanks.
