NAPA used to have a paper catalog I believe called a picture book o. Donf all their preformed hoses with ID and length and line drawing illustration of the hose. The last time I needed one the counterman had one hidden back since they do not print on paper nearly what they used to. Probably going to take some snooping and meeting a person familiar with that catalog. 
Gates makes many of the hoses.
That bypass circuit is critical to circulate the coolant in the block and prevent hot spots so fix it right or you could pay a high price.
I put a new water pump on a fresh rebuild gas engine and the pump was not drilled through blocking the circuit. Scored pistons twice before we figured it out. I think it might have kept the block and head from filling with coolant also.

dont know what leg lengths you need, but you can use this GATES NUMBER at an Auto Parts store and cut to size..

Thanks for looking but this one is short on both ends - like an inch on each end with a 90 % bend

yea... i think the "original" part is no longer available... You will probably need to get a 90 degree bend like above and CUT TO LENGTH.


another, with only one bend... but 6 inches long

I replaced upper rad hose on F2 and 8070. Same hose....just had to cut the right amount off correct end. "One size fits all"
