1972 454 bypass hose

[Anthony D.]

Hi all,

anyone have a good picture of what the water pump bypass hose looks like for a 72 LS5.

Searched and came up empty handed.

theres one in the guide but I cannot see if it has any lettering on it.

Thanks in advance!

it was painted with the engine from the factory. Car is gone, but saved pictures. Gary Bosselman did research on this.

GM Parts book dated July 1971, shows a 1485552 hose for that application.
A quick search on Ebay, shows several NOS available. Carlisle may also be a good place...
I don't think they had a part number stamped on them. They were painted as part of the engine assembly.
I have a very low mileage early 73 here right now. I'll look at it tomorrow and post a few pictures.

Here is a pic from my 5 star 70 FWIW. If there is more detail you are looking for, feel free to ask.

Thanks. Saw some on Ebay, with and without the ribs. Seems like they are without them.

This an early 73 454-equipped car with 5730 miles. I don't see or feel any ribs on the hose.
