582 rotary valve hose installs

[LSaupe 123]

Replacing the hoses on my 582 Mod 90 engine.  Using new OEM hose.  However the ID is significantly smaller that the tubes it connects to.

 

What a BEAR!  Got two partially on, but... there has got to be a way to do this (maybe preheat the ends in hot oil or something)?

 

Anyone have tricks of the trade on this?

I don't think oil is good on rubber - Doctor said, "Astroglide", (a water base) to help me get a big tube inside a small hole! 

Oh, but you are talking about engine hoses - Maybe someone has a better trick!  WD40?

I should have added these are the RV hoses, which feed/hold injection oil.  They are a rubber with a fabric exterior.

I used reinforced dishwasher connection hoses. Somewhat clear and much easier to deal with and 1/3 the price.

Put the hose end in hot water with a touch of dish soap (a drop or two, no more).

This will soften and lube them allowing them to be slid on. Using this method, I've used 5/8 and 3/4 heater hose on my and other 912 engines with great success.

You can slide a needle nose pliers in the end then pull it open to stretch the end a bit. then slide the hose on and it will shrink back down to its original size.

Actually my installs started to leak so I contacted LEAF.  The original cloth covered hose (gray head) has been discontinued and is replaced with a new hose (not cloth braided)) which is almost 2x I.D.  Went on great this time.
