Spider 2000 filler neck hose

Post by BradF » Sun Apr 14, 2019 1:05 pm

I'm replacing the gas tank on a '82 Spider. The tank came with the hose that connects to the filler neck. Any suggestions on replacing this hose would be appreciated. Thanks

--Brad, you may still have residual fuel in the old tank your are replacing. OEM '82 spider fuel tanks do not have a drain port, so you will either have to pump/suction fuel out. I use a OEM style fuel-injected fuel pump to drain the tank.

--Then, remove the LR lower quarter panel on the driver's side. Easiest if you jack and support the LR, and removed the LR wheel. There's a stud and nut inside the wheel well for the lower quarter panel that takes an 8mm socket/wrench that you will need to access.

--With quarter panel removed, you will see the protective (stone guard) that covers the filler neck hose. Remove it to expose the hose clamps on the hose. If you didn't drain the tank before removing this old hose, the tank will drain itself when you do. :lol: Unbolt and remove old tank. Install new tank, but do not bolt it down.

--The new hose is a tight fit on the tank and filler neck. Fit the hose to the filler neck, but do not secure. I use a small smear of non-hardening RTV (Permatex Ultra Copper) on the inside lip of the new hose to assist in fitting it to the fuel tank. Don't rush, or tear it. It helps to have an assistant lifting the tank slightly to aid in fitting the hose to the tank. Secure the tank. Secure the hose clamps.

It is important to use best quality hose and clamps on the Spider filler hose because the hose carries fuel until the tank is almost dry. The lower hose clamp at the tank must seal tightly. If the original clamp is not in good condition get another 2-1/2in double wire clamp. A screw type radiator hose clamp will not work. Here's some part numbers for the FI tank and background from the library. The hose must be cut to fit.

Re: Spider FI tank drain

If the Spider is fuel injected and has its original tank, the easiest way to drain it is to remove the fuel gauge sender from the top of the tank, raise the rear end enough to tilt the tank slightly towards the front of the car and use a simple gas syphon through the open tank top. Throw the plastic gas syphon away when done. They leak on second use from deterioration of the plastic bulb. The local big box home store sells them for $1.

I was in need of a filler hose for my Yugo but at the time seemed like it was a NLA part. I took it to Advance Auto and compared it to a typical radiator hose off their rack and cut it down. I believe the Yugo hose has a simply 45 degree bend in it so finding one was not a big deal.

It's probably not the correct type of rubber but has held up. Neoprene would probably be a better choice.

Neoprene is not known for its fuel resistance. Most fuel hose is made from a type of nitrile rubber.

Yes, radiator hose and fuel hose are different. Sometimes you can get away substituting one for the other and sometimes not. Fuel pulls the plasticizers out of rubber and makes hose rigid. Some years ago I had an Australian filler hose turn to rigid plastic in just two or three years. Looks great until I went to remove it from the tank and discovered it had lost all flex.

The Spider uses a very wide flat tank. The fuel filler hose comes into the side near the bottom. Fuel sits in the hose until the tank is almost empty. If the hose ruptures, you dump the fuel load.

I must confess I usually drain the tank in one of two ways:

- remove the filler tube (undo the top clamp), and rotate the filler hose (loosen the bottom clamp slightly), and let the gas drain into a pan, or

- position the pan under the hose and slice it open (if I’m replacing the hose)

The 2000 hose is longer than other ones, and so the first option above works quite well.

Apples to oranges:

The sending unit on my MGB goes in from the side and has a fuel pickup point coming off of it.

When I pulled the hose off fuel stated to flow out of the inlet port. I had a large Sterilte container underneath the tank. I stuck a hose onto the inlet port off the sending unit and aimed it into the container and it created a siphoning effect and emptied about 99% of the fuel out of the tank.

... a good point. Disconnecting the hose downstream of the fuel pump, and attaching a long piece into an appropriate container works very well too!

What's the consensus on what to do with old/contaminated gas?
