Gas line replacement guide?

rustednuggs · Posted: Tue Feb 18, 2014 6:27 am Post subject: Gas line replacement guide?

Hello - I have looked at a few posts and just making sure I fully understand this process as its very important. Replacing fuel lines!

I have a 73 Sportsmobile and the engine has dual carbs on it.

1.) Do I need to pull the engine to replace the fuel lines?
2.) Braided cloth fuel lines the best?
3.) New fuel filter with the little arrow facing the engine?
4.) A how to or good screen shots on how the lines get replaced? I was looking for something like the Bug-Me video but for the bus Smile

Thanks in advance

The most difficult part will probably be trying to remove the firewall with the carbs in place. Since you'll be removing the firewall, I would also recommend checking the fuel hose and pipe from the refill to the gas tank. Those can sometimes begin to leak with age. Not sure if they are available any longer for the '73. Seems like German Supply had a replacement but can't remember if it would fit our year.

barefootwestie - To remove the firewall that sounds like engine removal? Yes? "The fuel hose and pipe from the refill to the gas tank..its larger hose? I keep thinking about the one on the beetle.

No you don't have to remove the engine to remove the firewall. And DO NOT use the cloth covered hose...it used to be the best there is, now it's absolute shit.

No, i was able to remove mine with removing the engine. I do have a single carb but was able to remove the firewall without removing anything. Not sure about the dual carbs though. May be necessary to remove the carbs to make it easier.

Yes, the fuel refill is large like 2". Looks like this: Fuel Filler Rubber Hose Bus '72-'76

Cool appreciate all the insight, but if the cloth braided lines are crap, what would one suggest I use. Can I get these @ Napa, Autozone, or Oreilly's?

Thanks

I replaced mine with fuel line from Advance Auto 7 years ago and haven't had any problems. I just make it a point to check mine several times a year. I don't recall ever hearing anything negative about Gates brand.

Gate Barricade 30r14 low pressure hose.

Wondering also if the fuel filer should sit behind the firewall or under the bus. Currently its in the engine compartment. Like my beetle I would think that was a no no...and I should move it elsewhere.

Thanks in advance!

I used hose that was rated for high pressure fuel injection...a bit expensive, but it will last a long time...and yes, that cloth covered hose looks nice, but it's garbage compared to the FI hose.

Are those these filters?

I am finding I have several different sized hoses under the bus for fuel delivery. Just a lovely job..
Anyone in Indiana want some free beer? Come help out. Of course I prefer we drink after we are done with the fuel line replacement!

Those filters will be 7mm incoming and 10mm outgoing.

Have you been here?

Also are you using the stock mechanical pump or does it have an electrical pump? You need to know what size the hoses are. One of those cheap little calipers from HF is nice to own < $10.

TheSamba just rocks! Yes I hav ebeen gathering numbers from that site to start looking for hoses. Thanks for heads up...electric pump

Randy in Maine · Posted: Mon Apr 14, 2014 11:32 am Post subject:

Also if I might ad...

Once you figure out the hose size, go down to NAPA and buy a metal filter for $5. Some of them are 1/4" (~5mm) on each side and some are 5//16" (~7mm) on each side. Put it before the pump under the bus, not in the engine compartment.

Sweet advice. I hope they have everything I need, fuel lines, clamps, and this filter!

I like that Gates Barricade hose myself.
