I cannot seem to get the hose from the injector all the way up the rail. The old injectors I removed were flush at the top of the T. I tried saliva as a lubricant, but that didn't help. I tried twisting them up all the way. No dice. I tried wiggling them (twisting a little in each direction). No dice.

There must be a trick to this. I putting a lot of muscle into this w/o any kind of real success.

Should I try warming up the rubber a tad with a heat gun?

Thought I'd ask the group here before doing anything potentially stupid. Seems like the angle of the rubber elbow is making this harder than what it would be if the hose were straight.

The old golfers trick is mineral oil.

Thanks gents. The only product recommended that I have on hand is glycerine. Just gave it a shot and it worked.

I made mental notes on the other recos for future reference : )

I just use engine oil out of a little handheld oil pump.

But then it stays oiled and you risk it sliding off...and oil may attack/soften rubber.

The reason to use a water-based lubricant is because it'll evaporate away, and it's safe for rubber (the "personal lubricant" part...)

The other trick I discovered was to bend the elbow completely straight then slide it on. Bending the elbow totally straight was the only way I could the injector hose up all the way to sit flush at the T of the rail.

Y’all probably knew that already but in case any other newbies read this thread in the future, I’m mentioning it.

Last trick is that you dont need heat formed elbows.
You can use some spring stock cut to length & inserted
into the elbow sections so that once bent the dont
collapse.

IME, you don't need any of that. Just don't bend it super tight--and the fuel pressure will tend to keep the hoses from pinching shut anyway.

^^^ agree.

The elbow hoses are convenient but not essential. 3 in hoses (75mm) work just fine as long as you don't kink them during installation.

Agree that elbows aren't essential, but just using straight hoses makes working in that area and getting all the hoses attached to the rail a bit of a pain.

Becuase the J bend hoses are expensive and I wanted to make sure the right fuel hose was used, I just used straight hose and formed my own J bends via heat and inserting a spring inside.

Cut hose to 6" lengths . Tie the 2 ends together and heat in boiling water for 3 minutes to set the bend. Cool and untie the ends, trim to fit.
