direct gasoline injection on 2.0 L? that would require high pressures as stated. i stand corrected. i was looking at 2.2L service manual.

 

Thats what this forums for, two or three of us might get it wrong, but for sure one of us will get it right, SS is just a different breed in itself

 

just looked at the pics again. i dont think that schraider valve can handle 2200si. its not a high pressure type of fitting. i think its a low pressure supply line from the fuel tank. the high inj pressure is created by a pump on the eng being supplied by this line. my "silver solder" fix still applies. that fitting is for testing the supply pump in the fuel tank.

 

You know I think your right, I just looked at mine and from that unit it feeds the engine mounted high pressure, cam driven pump that provides the pressure required of direct injection, since he'll have to remove it for repair, if it were me I'd replace it.

 

that kind of repair is right up my alley. im a farm equipment mechanic. ive seen and done all kinds of repairs like this. the repair would be more dependanble than oem. oiften i dont have the option of replacing parts and more often than not i have to find ways to repair. inspiration is my speciality. by the way, im not talking about normal solder like in your house plumbing. silver solder is used for ac lines, saw tooth carbides, etc. much stronger than solder. that fitting is probably silver soldered from factory.

 

found out that line is the low pressure side and the round silver disc is the pulse dampener used to smooth out the fuel when it goes to the high pressure side to the pump. and yes that valve is used to pressure test the system.

I probably will replace, right now I used the Toyota FIPG to hopefully seal the leak for a day or two, will know later today as it is curing as I reply.

since I would have to remove the line to do the silver solder, it may be better to just replace the line with the valve....and since I already have the FIPG on the line, that would have to be completely cleaned off before any additional repair....
also have you ever used the kit used to repair gas tanks? it is supposed to get as hard as steel, I may have to do that if this repair doesn't hold up to get me through the next few days for replacemnt part or to silver solder.

 

bad move on my end....the FIPG did not do the deed, live and learn, out to get the tank repair kit, hopefully that will work..........

bought the Liquid Metal that is supposed to be gas resistant, so we shall see once more. it seems like a better move than the tank repair kit.

 

Better keep a fire extinguisher handy - you don't want to be messing around with attempting a repair with Toyota FIPG, and now with "liquid metal". That is just playing with fire (literally).

 

Good that Rainman cleared this up re fuel pressure, but as far as the ChevyMax article is concerned, we're probably referring to 2 different articles. If anyone wants to see the ChevyMax article that I was referencing, I found the archive (Volume 3, Issue 5). They specifically addressed the LNF in the article, in which they mentioned the performance advantage of using premium fuel as well as the fuel pressures.

It's a great article for the SS, I actually printed a copy and have it in my build book along with any and all info I come across plus window sticker and pics of all work done on my car
