Title: Running fuel lines
Post by: 65bug on January 23, 2013, 23:23:55 pm
Hi guys,
     I have a question regarding fuel lines and how to run them. I have a 65 bug with a 2165 motor. I am running dual 48 DRLA dellorto carbs. My fuel line is so embarrassing looking I dont want to show how it looks underneath the motor!
     Basically, it's a mess. What I want is a nice straight, or a semi-straight shot from the metal tube to the back of the engine tin hole that it goes through into the motor compartment. I don't want hot air blowing on it out of the shroud air exit duct.
      I want the best safest fuel line there is, and don't want it hanging in mid-air from the hard line to the hole in the engine shrouding. I was thinking of clamping or mounting some type of hard line fitting into the hole in the shrouding???? What do you guys think??
      Then a 90 on the inside to route the line up to the drivers side carb. Any suggestions or help would be greatly appreciated.

Thanks ;)

 Install AN lines with a bulkhead fitting,     http://www.jegs.com/p/Earls/Earls-AN-Bulkhead-Fittings-Nuts/749420/10002/-1        ,    clean and safe.  Mike McCarthy

.250" stainless, plenty enough for my 2180 with IDAs.

Left is for my oil line and the right is for the fuel line.

Thank you Mike! Any benefits with aluminum over stainless other then weight? Those look nice!

Glenn,
     Thanks for the pics! Looks good. I think I don't need anything really fancy. Your not going to see it anyway. But I want safe and my gas to stay as cool as possible traveling to my big carbs. If I route my own stainless lines I need more tools. Hmmmmm, maybe a combo of fittings and the good rubber/canvas fuel line may do.
     Need to get under the car and take some pics and have to draw up a plan here... :-\

Not the best pic but maybe it is of help.

I have a bulkhead fitting (below the coil) and all AN6 lines in the engine compartment. This way I only have to disconnect the fuel lines on the IDA's when pulling the engine. From the metal pipe in the frame horn to the bulkhead fitting I have a rubber hose with a fuel filter in the middle.

Jesse,
   That's ALOT of help and gives me some ideas too! Thank you. That's more along the lines of what I want to do. I'm sure nothing beats or out lasts stainless, but hell i'm 47 years old. I thiink with a good quality hose I will be good to go!
    I'm wondering what the coolest(temp) route is to go. Mounting to the firewall across from the fan in the back would seem pretty good. There's a big stream of fresh air coming in there. I think this is a "Shoulda done it before" the motors in type of deal.
    I think I am going to re-route my stainless breather lines and get some 90's for the one going to my right carb. I got room, just not sure where.....
       Here's what I have to work with:

This is normal fuel line....?

Sizing differs from 'normal' fuel line. This is AN6 size.

Is AN6 the stock size fuel line?


Title: Re: Running fuel lines
Post by: glenn on January 24, 2013, 21:48:14 pm
AN6 is 3/8" and stock is 5.5mm which is slightly smaller than 1/4".

check www.aeroquip.cc

I got way better prices there than I could get anywhere else, including summit.

Also look for JIC. Almost all of the AN hardware out there is JIC. the only difference is that the manufacturer bills exactly to military specs for AN. Real AN has a spec number on it and is really quite rare outside of military applications. It's just that people take advantage of the lack of knowledge and refer to JIC as AN and charge accordingly. Get JIC at most industrial hose shops for cheap.

Great info You guys! Thank you! I mounted mine today and it was a piece of cake. I purchased a industrial 1/2 Bulkhead fitting with a 90 on one end. Bolted it to the hole into the engine compartment! Used a German lock washer to keep it from even vibrating loose. Put a new piece of fuel hose on from the hardline to the bulkhead. Very clean and safe now!
   Question: What can I use if anything to shield my hose from the heat. Or do you think that even needs to be done ?
   Thanks!         PS Will try to post some pics tomorrow. ;)
