Bleed valve on universal m25xp

[ChrisCall]

I have a question i replaced my fuel filters on my universal m25xp. When I was bleeding the air out I broke the bleeder knob on the valve . I have the new part and I'm going to replace it this weekend but would like to know if I need any type of thread sealant or just thread it on dry ?
Thanks

on my M25 that valve is sealed with two copper washers. You might be able to anneal the existing copper washers to re-use them, but you either need to do that or replace them.

<<<EDIT>>>
Ignore the above - looking at the diagrams on the TOAD site that part is different - and the copper washers on my engine secure a female threaded part that the bleed valve screws into, so IIRC I used a ground Teflon rated for fuel use. Teflon tape is NOT recommended because pieces of the tape could get introduced into your fuel system plugging up the injectors.

Thanks. I've got some permatex thread sealant rated for fuel.
