This is on my '35 Ford. I have a 96 corvette fuel rail and the nipple for the hose comes off in a different direction than that for the 97 camaro rail I had so the hose will not reach to the passenger side of the intake manifold like it did. Can I move this hose to the driver side (where the EGR solenoid was) or should I find a longer hose to reach to the passenger side?

Second, am I able to shorten both hoses for the opti? I am more asking about the hose with the filter/flow reducer and backflow prevention valve. I wasn't sure if those two are spaced a certain distance apart or something on purpose.

Lastly, my brake booster is under the floor in the car. Is my only option to run the vacuum hose from the intake manifold all the way under the floor - about 4' or so long? I suppose there is no choice, but a 4' vacuum hose seems like it would be pretty ineffective.

Thanks! Some things seem obvious to me, but problems have arrised after I have thought something was obvious.

 

Either solution will work. The FPR and the EGR nipples are both "full vacuum" ports.

You can shorten the hoses. There is no critical spacing dimension for the devices in the line.

There is no significant "flow" in a vacuum hose, so as long as the diameter is adequate, length is not an issue. The stock LT1 hose is pretty long. If you are concerned by the extra length (it could "dampen" the vacuum at the booster) use a slightly larger diameter hose than the stock hose.

 

Thank you, sir! I want to thank you, as well as Shoebox and shbox.com for answering all my questions and helping me get all kinds of little things sorted out over the last couple years or so since I removed the engine from the camaro. A couple of weeks ago we fired the engine in the car for the first time! and we're real close to having the car driveable as well. It feels good and would have been much more difficult without you, Rob and the others around here.

Well that pretty much answers everything. My only concern is being able to feed a vacuum hose down by the steering, wiring, pedal arms, frame and make a sharp left turn toward the booster without kinking it or being able to use a molded hose. I assume I will only be able to find a straight piece of hose that long. Maybe I could add a 90* fitting to turn it toward the booster? Any ideas on sources for a 4' rubber vacuum rated hose?
Thanks again.

 

Use a piece of metal tubing and bend it to fit...the rubber hose will only have to go from the engine to the metal tubing to allow for engine flex and from the booster to the metal tube. Should be a easy fabrication.

.

 

I don't have a tubing bender big enough for 3/8" but that's something to think about if I run into too much trouble keeping the hose away from everything else.

 

I'm not sure what I was thinking...I used my tubing bender to bent my 3/8" fuel line so bending up a 3/8" hard line for the vacuum hose will be no problem and I can just cut up the stock camaro vacuum hose for the ends. Thanks!

 

I almost bought a 3/8" hard line to use, but it is too small. Is the vacuum hose 1/2"? Advance Auto only carries up to 3/8". I was thinking about using 1/2" conduit. It sounds a little ghetto, but seems like it would work just as well, right?

 

Hardware stores might have what you are looking for, gotta be better than conduit.

 

hardware stores don't seem to have brake supplies

 

...but sometimes they can be "brake supplies" if you use your imagination.

 

Actually a half inch conduit painted black would look fine and function for the task properly.

 

my imagination tells me to use conduit (if I can find the right size)...what do you think

I think half inch conduit and half inch hose must be measured differently because half inch conduit doesn't quite fit on the existing hose. So 3/8" brake line is too small and 1/2" conduit (smallest I found) is too big .

 

Take the existing hose with you to the hardware store (Home Depot...etc.) and see if it fits any conduit pipe..or you could even use a copper water supply pipe as well.

 

yea i took the hose with me yesterday and 1/2" conduit was the smallest they had. it would probably fit if i really forced it on, but i thought there must be something that will be a better fit. so im still looking i guess.
