Help Modifying Bosch 1600cc Injectors

[RETed]

Yeah, silicone hose swells like a bitch when exposed to gasoline, but in theory, the gasoline should not touch the lower grommet.
It might if you have a fuel leak from the fuel rail...
There are even some lower grommets that I've sourced that are made from silicone from the local auto parts stores.
I check my lower grommets often enough that I've never had a problem with gasoline touching them - this has been over a 5 year+ period.
But the standard warnings do apply here...
I just like the silicone hose better since it makes for a cleaner and tighter seal when cut to length.
Most fuel hose is reinforced with some kinda (Nylon?) braid, which tends to corrupt the seal a little.

Good luck.
