I am swapping in an '89 460 EFI (EEC-IV) engine into my '70 F250. One of the vacuum lines is broken and the rest missing. It is a pink one that comes from a vacuum valve near the coil and EGR and runs across to the pasenger side of the engine. The vacuum diagram is unreadable on the engine. I have bought every book I can find. The diagrams are so small I can't make out where it goes. It looks like it goes to a device labeled "SRV". What the hell is an SRV? Anybody got any ideas?

I am on the same thing my srv line broke i dont know were it gose i called the ford dealer an they said it should go to a main vac line but i still am not sure any one know what srv means.

 

Ohoh. I may have to experiment...I got tangled up in a mess. MaybeI should find a similar engine that's running and 'copy' the vaccuum hose lay out. I have a '79 motor home and got a 'used' engine froma junk yard in Montana, and the hoses were all cut. I am embarrassed to say that I did not label the hoses (or the wiring)on the old engine before I pulled it out. I have been unsuccessful in finding a diagram for this engine. Any ideas?

Welcome Frosty!

What can you tell us about your Motorhome, and the Donor truck you took the engine out of?
Year & model would be a great help, and what brand & chassis 1979 RV.

 

I'd have to call thejunk yard that shipped the engine to me to findout what the donor truck was. The 79 Ford I have was a 'yard sale' item which I opened my big mouth and made a ridiculously low offer (the next day a kid showed up saying"Grampa wants you to come 'n' get your motor home"). It's a Coachman / Leprechan. I've been saying it's an E-350 (a guess). I'll call the 'used parts' yard now to try to find the donor truck spec's, but Id like to keep the rig as original as I can. I could be talked into selling it (I'm too oldto have more 'projects').

 

Can you take a picture of the engine you have now?
There should be a sticker on the valve cover with the emissions compliance # on it.
That would also have the model year of manufacture.

 

So it's from an E350 van, you don't say the year...

Can you see the sticker?

 

Lloyd saysit'sout of a '79 1T van (sorry for the delay, some others don't know what I'm dealing with here).

 

I'll get a pictue ofthesticker (Right side Rear has a EGR and so on). It may take some time to get pic's on line ,as I'll have to figure out how to do it...

 

No rush, this forum isn't going anywhere....
