Rubber fuel line

[71bigblock]

I want to run the rubber fuel line for my truck.  It has a 5.7 Hemi in it, so I need stuff approved for EFI.  I found this stuff on ebay a guy's got, looks pretty affordable.  I asked him if it is approved for EFI, he said he didnt know, but it says EFI on it.  In the one pic I can see it says EFI.

Sooooo, would I be safe using this stuff?  Thanks.

You could pay that for 3" of the stuff. 

I say it's worth the gamble.

Yeah Mike, that EFI stuff is spendy.  The cheapest I found it around here is at Fleet Farm, at $2.59/foot for 5/16" line.  That would be a killer deal if I can use it.

Are you trying to go from the tank with that huge roll of rubber line?

Fuel Injection has 2 different pressure ratings. Throttle body had  around 14.5PSI, Multi-Point or PFI went to 35+PSI your Hemi needs at least this much. Is this rubber line rated for that?

I would run steel tube most of the way & use High pressure FI line with double FI clamps to connect with

What do those double clamps look like CP? 

I kinda planned on running rubber the whole way, I hate bending steel lines.  I dont want them to rust, either.  Stainless is too expensive. 

What are the disadvantages of using rubber line?

Not really sure, that's why I asked him.  I think I'm going to pass on that stuff, thanks.

That reminds me of a kid I went to automechanic school with.  He used like a spool and a half of fuel line going from the tank to the carb  in his Caddy Fleetwood. 

The funniest thing is you could see the fuel line drooping under the car when he was finished, looked like someone hanging Christmas lights under there.  We were just waiting for him to catch the fuel line on something....

Please don't run rubber the whole way.   

[GoodysGotaCuda]

Please don't run rubber the whole way.   

I definately agree, its pretty tacky looking. Its not the safest thing given under the car can get hit with debris and rip the rubber line.  Stainless braided line is another story, plain rubber is cheaping out on the system, and not a good corner to cut. .02cents

Ok, I'll start pricing.  I would have done it right, fastened it right, etc. 

But if you guys say so.  You all have much more experience than me in this stuff...

Thanks.

Steve,
you can get your own metal line and bend it yourself. Get a flanging tool, and a bender. They're pretty cheap, and you can get creative. Think about the amount of time it would take that new metal to rust. I think you'll be safe. I bet most of us have the same 38 Year old metal lines under our cars, i know i do! 

Oh, if you flare your own line, make sure you put the nut on first!! 

[Chryco Psycho]

the FI clamps do a full wrap on the line & are better for higher presser than the worm gear style
 Make Sure you use the double flare insert & put a bubble on the end of a steel line so the clamp cannot slide off the end of the tube

71bigblock,
If you don't like bending steel tubing, how about getting a roll of 5/16 or 3/8 aluminum tubing? You can bend that a lot easier than steel tubing and it's also a lot safer than running rubber hose from the tank to the carb. I've used aluminum tubing on a few cars and it's worked real well for me. Just a thought.

fuel injection rated hose always has the spec printed on it
