Opinion on Gas Line Replacement

[Bill72BB]

I got the bug to clean up the rubber gas line on BB . I'm running the EB 1411 and an electric fuel pump , I need to get to where the original fuel pump was . I was thinking of making a new line ,or using Summit or Russell SS braided with all the assorted fittings , I'm leaning toward trying to make one out of Aluminum or steel tubing . I've got a flaring tool and 3/8 tubing bender .
Would like to know what would be the best way to go ?

i also need to run new lines in my truck (supply + return) for the new rear tank, pump and LS1 upgrade - so i want to add on to your questions...

is it better to buy a 15'-20' pre-made braided hose with -4 or -6 AN fittings and tuck it inside the framerail, or to actually bend your own lines?

for ~$110 i can get a single pre-made braided line from Aeromotive or some other company...or I can bend steel lines to run most of the way and use braided "patch" cables to run from the line to the filter, then to the regulator, then to my fuel rails. which is recommended?

Is there some clip (got a part #?) which will hold bent lines to hte inside of the framerail? anyone got a map that shows default locations for these clips?

also, is it recommended to ONLY run the lines inside the framerail for protection?

You can get through Summit I believe a 20' steel tubing, going the braided way is pretty expensive, if its not going to be a show truck go with steel, easier to tuckup & away. Also you will need minimum 3/8 to injection & 5/16 return, You can get all different sizes of steel tubing, just do a search for steel tubing and it will put you right there. Flairing ends at first is a pain but is actually pretty easy once you do a few. setting up braided stainless lines can add up quick, figure about $2+ an inch Plus add on any elbows/fittings etc.

Personally I will only use double flares for extra strength. All of the factory fuel and trans cooler lines are double flared. John

I don't know that there's a "best way". My general feeling is that run a hard line wherever you can for durability and safety. I'd sure keep it inside the frame rails, but that's just me.

On my '72, I cut the hard line in the frame rail about 2' back, put on an AN-4 (1/4" line) tube nut, AN-4 to AN-10 reducer, Aeromotive filter, AN-10 line to the Edelbrock mechanical fuel pump and then AN-6 (probably should be an -8) up to the carb.

IMHO, I'd run a hard line as far forward as you can, then buy N feet of -6 or -8 and the required ends and make up the rest of the lines.

For mainly expenses the Steel line is far better, I also think it's much cleaner looking than doing all the braided stuff. Also not that braided lines etc are bigger and if your using stainless or steel braided expect your fingers to look like ground beef if your not careful. As far as whats better, I think steel is way easier to setup and less chances of leakage, I have fought to many oil/fuel/trans/brake leaks using braided lines and specialty fittings. They do look nice though.

fortunately for me, they just opened a Summit store here in Atlanta (maybe a little ways south of town from here). definitely need to make a parts run one of these weekends.

When making the steel line do you single or double flare it ?

[Bowtie67]

Gas/trans lines only need single flair, brake lines should be double flair

Single - note that an AN flare is 37 degrees.

Braided line is still rubber tubing, plus braided can be a pain in the a$$ to keep looking pretty. Go steel.

[shifty]

Does anyone have a recommended AN single/double flaring and also a bending tool to use? any tips on flaring and bending lines?

i'm just wondering what i should buy in that regard.

also, any word on frame clips? Is there some special frame clip that will hold down gas lines?

[Bowtie67]

I only posted only needed flaring, I usually do double flaring on all my lines.

Shifty most automotive parts places have flaring tool kits, I dont even think you can find a single ended flaring tool. Pipe benders are also common in most autoparts stores, as well you will also need a small tubing cutter something that can cut at least 3/8 tubing, also dont get one of those little micro jobs they are a pain in the a$$, they work ok if you have to get into tight areas to fix a line. Youu can also pickup a desent tubing cutter at most hardware stores that sell plumbing supplies.

Here is a tubing bender I use and works well, usually covers 3/8, 5/16, 3/16, 1/4.

Most flaring tools will have directions in them to do flaring. If you need a little more I can dig mine out and snap some picks on how to do flaring, I probally have some old tubing around. On the bending it is take your time, dont rush it or you will collapse the line. When laying in a line make sure you are going to have enough, kind like running wire you dont want to come up short. but like wire you can splice..
