Hi wondering if anyone would know where we could find a diagram for vaccum hoses for a 1984 454 cid engine? Any help would be great.

I was able to download it. If you want to post it again or send it to me I'll reformat it and host it on my site as a picture link.

OK, I was able to convert it. I am way over my head in Photoshop. Here it is on photobucket and as a jpg attachment:

As for vacuum hoses, be sure to buy hoses that take the extreme heat of an RV. I have had the best longevity with the orange silicone rubber hoses sold by NAPA.
