Ec250 fuel tank inserts

[Scotty97]

Does anyone know what plastic the fuel tank is made out of on my 2001 ec250.

The screws on my rad shrouds keep coming loose, so I want to bond in some brass inserts, using plastic weld.

Cheers

I have had good luck with cleaning out the old plastic plug and replacing it with one of these wood insert nuts cut down to the proper length. you can install them with a screw and jam nut.

Ok Thanks

Some people have said to use 'Permatex' to hold the inserts in.

Anyone tried this??

does anyone know which permatex product to use

You could also melt a p-tex stick into it and reuse the same screws.

Barbserts may also work, but are expensive. You could also look at Speedserts:

Well I just removed tank and somebody had botched the inserts.

One was made out of piping, another out of a dust cap.

And they also missed with two of the screws and pierced the tank!

Well that sucks, but can you let us know how thick the tank is there? That will help determining the proper size insert for future repairs. Thanks.

I didn't measure it, but I'd estimate the holes where the inserts go are approx 7mm deep, but il measure tomorrow with a vernier.

The thickness of the tank where they missed and screwed into tank is only approx 1.5 to 2mm thick

Thanks, how are you planning to fix the holes where they missed?

 

[Scotty97]

I'm not sure yet.

I have ordered some plastic welding rods, and some p-tex.

The previous owner had sealed it with another screw and black RTV.

Any ideas???

I was thinking the p-tex. I'm not sure if it is resistant to gas however.

 

[Scotty97]

I'm not sure either, never used it before.

Maybe someone on here can tell us if it's fuel resistant.

If not, may be I can make a plug to seal hole and then use P-tex or plastic weld to retain it.

I think it's going to be trial and error until I find a solution

 

[Zman]

Rtv is not gas compatible. It turns into jelly.

 

[Scotty97]

Yeah, that's why I removed it, it was probably just the screw plugging the hole and the RTV being retained by screw.

 

[Scotty97]

Well I managed to fill the two holes where the previous owner missed the inserts and screwed straight into tank.

Not bad for first attempt at plastic welding using a soldering iron

Does anyone know where I can get a new tank for my 2001 ec250??

Wouldn't mind a Clarke oversize one.

I have tried the P-tex fix, and plastic soldered the holes up, but both start to fail after a few rides!!

Its sunny in Wales, which doesn't happen often and I can't ride cos of my tank!!
