FUEL LINE

[FATBOY]

what is the best type of metal to use (legally) and where do you get from i,m running an injected 5 litre

You should be able to use "bundy" tube, the same gear that is used for brake lines and trans lines. Give your local brake/trans shop a call. They should be able to get the size you need.

Hi,

I re-routed my lines using copper and rubber hi pressure hose to eliminate stress cracks from vibration..  in retrospect I would use Stainless lines avalable from VPW.

To join the rubber hose to copper line compression fittings (Russels and Earls) were used to ensure no leaks under pressure (EFI).

the decision to use copper was based on the recommendation from ENZED.

they also stated, the bundy tube in the diameter I wanted would have been too difficult to bend hence the recommendation to use copper.

I bumped up the diameter of my lines to 3/8" since i had to re-run the lines anyway.  I also incorporated an external under floor surge tank.

BrakePro has up to 5/16" line which is steel, which should be OK.

Cheers

..Amazing...

we are having some stainless lines installed at work.

for fuel line in stainless steel!

try Fluid Systems Tecehnology

if only i found out earlier.. should of asked a plumber!!

Hope this helps.

just a quickie on the fuel line subject
the original lines were copper, but what diameter?
IM running twin carbies, is there any advantage of using a fuel block/rail or would using the direct line into the carby sufficient?

[mcl1959]

The original lines were actually steel.
Fuel rail is not necessary, just plumb in both carbies.

steel eh? sorry to be a pain, but can steel still be used for fuel lines? i know that there has been a lot of discussion about that materials can and cant be used for plumbing lines. would there be any advantages of using copper, as that what was origianlly on my motor?
maybe im looking into this too deep... :-/

Hello,

Fuel lines should be well thought out, and constructed of appropriate material...  "What is appropriate" I suppose is the main item open to interpretation.

I used copper lines, it is easy to bend, cheap, comes in the appropriate diameters, easy to purchase from any shop.. eg pirtek, enzed etc.

Steel on the other hand in 3/8" diameter I was advised, is difficult to bend, hard to purchase (couldnt find any), but it looks better than copper IMO.

I have seen some ppl discount copper as appropriate due to it's soft nature, however I dont see the problem if the lines are clamped down securely at regular intervals to eliminate vibration, similarly the lines should incorporate flexible hoses when joining a moving part.

Obviously dont route directly above or near heat sources, or place the lines in areas where they are likely to be snagged, broken or hit by road debris.

Continous lengths of rubber or braided hoses would not be recommended either.

so steel can be used to plumb ur fuel, and would probably be the best option.

Copper isnt orignal and has advantages of being easier to work and easier to get.


hope this is of some help.
