Oval gasket in Trunk for Fuel Lines

Post by qwik510 »

Has anyone found a suitable replacement for the oval shaped gasket that the fuel lines go through into the trunk?

I am working on my fuel system and need to tackle this part soon.

Thanks,

David

Isn't this the same part as the gasket for the fuel lines entering from the fender well into the engine compartment? There was a lot of talk about this on the BB list a year ago, or so. Someone found something that'd work, IIRC.

I just use some split fuel line, no one sees the trunk hole except me.

I would like it seal off for exhaust fumes, etc.

Thanks,

Gotcha. No issues with my setup, but someone on the BB list should have the result of the past conversation.

Dug and dug and...finally found what I was looking for:

From: "Armen Assatourian" <Armen.Assatourian at uav.com>

OK guys, I ordered the 238.020 & 238.021 grommets from scottsoldautorubber.com. They were about $15 ea and $9 shipping from Australia. I ordered both just to see the difference and to see which fit better. They look like they come out of the same mold and they measure the same so I'm not sure why they have different dimensions on the web site. They both measure about 1.20 X 1.93 on the outer dimensions.





The 238.020 has 2 holes in it as you can see in the photo. The small hole is at about a 45 deg angle.





The 238.021 grommet has the small hole removed and the large hole is closed off by a fairly thin wall.





Since it already has a hole in it, I installed the 238.020 in my car and it fit pretty good (see photo). It fits tight as far as the groove to sheet metal fit. But it's a little small for the oval hole. When installed, if I push it to one side, the outer edge of the grommet just barely starts to expose the hole in the panel. A simple fix that should work is to install an o-ring into the groove of the grommet to fill that gap. That should keep it snug and centered in the hole. BTW, in the photo of it installed, the grommet looks larger on one end. It's just an optical dillusion. I think my camera lens distorted it. You can see in the other photo that they aren't like that.





I plan on using the 238.021 on my car. I just need to punch a hole in it that fits my fuel line. I'll put the hole in the thick section, not through the thin wall in the existing hole. It's so thin I think it would eventually start to tear.





So, based on the alternative off the shelf choices, which are zero, I think it's a pretty good option. It looks almost stock (if that's what you're looking for) and fits OK.

Well I may have found an alternative off the shelf replacement for cheap.

How about $2.18 including shipping.

The seem to be close to the correct size. I ordered one and I will try them and let everyone know how they fit.

See them here:

Beats split fuel line, for sure.

Well I just got home and the mail man delivered the oval plug I bought from eBay today. I ripped it open, ran out to the garage and gave it a try. It fits perfectly. Not over tight, not loose at all, just a nice snug fit.

Here is a crappy cell phone picture I just took.

For $2.18 this is a really nice cheap replacement for the NLA factory part. You will need to punch your own holes in it for your fuel line but that means it is able to accommodate many different sized fuel lines. I am running 5/16" ID braided stainless lines so I can just punch a hole a little smaller than the hose and get a nice tight fit.

I am glad that I was able to find this and share it with all of you.

One more good part to keep our little 510s on the road.
Enjoy The Ride!

BTW,

I am pretty sure this is the same size as the one in the engine compartment too. So order two and you will be set.

Ten years plus! Bringing this back from the dead to see if anyone has found a particular plug for this more recently. The original ebay link is understandably an error now.

The old auto rubber part numbers above look to be still available, but they are really too small. I measure the hole at 30 x 50 mm. I can find 30 x 60 or 25 x 55 grommets currently on ebay (China/Hong Kong). Maybe they can be squished or stretched in there.

Thanks.
