Gas tank Angle

[tbjaus2000]

When installing a gas tank. How do you know what the correct angle of it is so the pick up hose doesn't run dry before it should? Sound stupid i know.

not stupid,

There are manditory guidelines as to tank mounting and orientation.
Basically, every tank I have ever intalled has had a big welded seam that faces the "12 Oclock" position when mounted correctly.

The common tanks have the valves mounted on the side in their own little compartment which needs to be around the 9 o'clock position

I have attached a photo to make expaining a bit eaier.

I am sure V8 patrol will correct me if I am wrong, I have seen people mount the tanks such that the top of the valve enclosure is at 9 o'clock as opposed to the way the one in the photo is mounted.

For further clarification a gas shop will let you know and most suppliers have charts up showing acceptable mounting posiotions and orientations

If the tank is manufactured with mountings welded directly to the tank and its made for your excact same model vehicle then you mount it up wherever the manufacture intended and it should all be apples.

However, if your tank sits in a cradle then its final resting position depends on the manufactures instructions, usually involving a spirit leveler and a certain position the leveler has to placed so that its dead vertical or horizontal. Some have like a detent in the mounting so you cant go wrong. Best ring up the manufacturer of the tank or a LPG workshop for the correct instructions.

Depends on the make of the tank !

but the above posts are a pretty good "guideline" by which to go by.

All tanks have a certain angle in which they must sit but this angle varies between the manafacturers.... some have the sub compartment @ 90degrees to the floor some have it at 45 degrees..... its a long list ... trust me !

Best bet is to contact the manafacturer of you tank and ask them for the exact details if your gunna be super fussy.

tip:
the "recemended angle" is good..... but ...... by droping the angle down a further 4 or 5 degrees you get about 5 lits extra of lpg
dont over do this as the opposite occours and the end result is much less LPG than it can hold
Example:
My commodore has duel tanks ....... capacity is 134 lits total..... alter the angles on both tanks by 4 degrees and gained an extra few lits ...... capacity now 142 lits.

Thanks for the help. The tank is a APA D100 i think! First stamped in 94. I am under the impression is a D100 but the valve assembly does not look like current tanks. The tank is from 94 so it could just be that? In which case i can only assume is a standard 30 degree tank. The tank is not designed for my truck so to speak. Any other suggestions. Might be a case of trial and error to find the ultimate fillage/useage!

It will be out of date get it tested before you put it in

Range Rover - It has been retested. Thanks. Did the earlier tanks have a different style of valve cover?

No worries, how much did that set you back ?

The laws regarding LPG tanks changed constantly and as a result many manafactureres had to change designs of the cradles / valving setup and sub compartment.
I recall that there was a stage that single bold cover plates on the sub compartment were being discussed and later they were deleted from all manafactureres designs..... Im not sure if it was passed as a law or addopted as a better design by the manafactureres before the powers to be had their way.

If your tank is external then it wont need a cover plate....... but if its internal it WILL need one and it must seal the valving and hoses entering / exiting the sub compartment and vent them externally.
