^^^For any HFS system you are correct. The Surflow pump can not stand up to the harshness of the mixture. (mine is the 2D with the Aquamist pump
)
I have played with all mixtures including M5. M5 has potential to make the most "POWER" of all the methonal mixtures however I wont be running the Aquamist race pump for ever (soon upgrading to HFS-5 for the meth 2d for water). It took me hours on the dyno to prove M5 could make 12-15 more whp from the added oxygen it provided, but to do so it made me have to change my tune a lot. (Just not worth it)
Phenixfyah-VP said that because: Most people who are running a injection system are using 100% methonal due to how much more easy it is to extract power from. Being that is the case, 100% methonal being injected into a hot pipe by a nylon hose with 5% nitro can combust. If it did combust you looking at a picture. The nitro will provide enough oxygen to the flame... BOOM, your motor could easly be done. Even worse the whole car including even you depending where the flames starts. Just a big pipe .
Evoryder I know you have used 100% M5 with success , Im sure you have taken the precautions necessary to be safe.
Under a 50/50 mixture its a whole lot less volatile. Water helps keep it under control. I have tried to ignite this mixture on fire, before I dared put it in my trunk. No flame. I doubt VP had water as part of the mixture being injected in mind when they wrote this warning.
OP-
M1 methonal is easy and safe, any VP dealer can order M1 you just might have to wait. Chemical supply places usually have %99.99 pure meth try one to see.
Good Luck!
