^Not to mention scary. Wouldn't want a stray spark or heat to ignite that stuff!

 

I just got a SMC, wonder how good its going to hold up,...

 

just an update for those who care....the RTV Silicone is still holding up with no leaks. so I guess its safe to say that it works.

 

Good to hear that this is an easy viable solution to fixing BS pump leaks that plague us all.

 

I used to run 100% meth after a year of running it my pump failed. Got a new pump was running 100% again then after talking to a few people I changed my mix to 80% meth 20% water. It seems to run a lot better now with that mix. Correct if I am wrong: The meth part is good for add points to the fuel and the water cools the intake charge. Meth is the reason why you can turn up the boost. Am I right some what?

 

SMC v2 here. 100% meth and no leaks for over 4 years.
Still works great but I might rebuild it soon just to be on the safe side.

I'm wondering the same thing as the OP, but i run 100% denatured alcohol in mine.
Snow V2 with no leaks for 2 years so far. "kow"
Any similar problems you see happening with the alky?

Running a Hyper-Drive 100% meth in mine (or denatured alcohol depending on what is available at the time), no issues so far.

 

Also knw as "suck my ****" sytems (BIG AL) but it amy work for you the actual pump maybe pretty good but the injection box sucks and fails over time keep and eye on it anytime youre beating on it

 

I use straight meth and i have two pumps(one for spare). I havent had any problems with it myself other than the pumps leaking. At first it was the connectors so i got extras and then the pump started leaking so i got the extra for that too. I eventually got so fed up that i put gasket maker in one of them and havent had a problem yet

 

I'm using the HFS-5 pump system and had a leak about a year ago. It was due to the o-ring and spring under the bottom plate. Once replaced, everything was fine. I'm using 50/50 though and not 100%. I heard using 100% will eat up the seals in the pump quicker. Also, if you have the money, you should upgrade the tubing to a teflon material. They can withstand just about any chemical you can put in a car.

 

yeah my RTV solution worked, but now im running E85.
