Fuel odor in trunk

[aarvig]

My trunk is entirely sealed from the outside environment. However I have noticed a fuel odor when I open up the trunk. It is most definitely coming from the inlet pipe. I have tried three different set ups to try to seal the vapor off at this area. I am currently using a sealed hose similar to that for marine applications from tanks Inc. along with T-bolt clamps To secure it.  Took it out for a drive tonight and noticed that I still have fuel vapor when I open the trunk. It is not coming from the fuel pump area or the fuel sending unit as I have inspected those.  The smell is strongest at the hose.  I am wondering what you guys are using in this area?  This is my set up:

are you sure its not the tank vent of the other side?   Are the walls on the driver side sealed to the body?

Aaron,

If you have this hose from Tanks, https://www.tanksinc.com/index.cfm/page/ptype=product/product_id=867/category_id=200/mode=prod/prd867.htm
It is only rated to SAE 30R7, it will allow much more permeation than a marine rated fuel hose that is certified to SAE J1527.
Permeation rate standard for each hose type: 30R7 allows 550g/m²/day vs 15g/m² to 300g/m² /day for J1527 depending on application and designation (A2 or A1-15.
You might be better off with this hose possibly: https://www.fillernecksupply.com/2-inch-soft-wall-rubber-fuel-filler-neck-hose-sold-per-inch-saej1527-rswff2/

That has to be it.  I’ll upgrade the hose and report back.  Thanks for the links!

Definitely not the vent.  That is well sealed from the trunk…

It can't hurt and should improve the odor. The hose is not designed to hold fuel just convey to tank, so if you over fill and sloshing around up the hose, it could make it worse.

Aaron,
  Did you solve the issue?  My fuel tank had some leaky welds, so I would not be surprised if some of your upper welds were bad. 

Good luck,
Jim
