SMOKE' EM

I want to put a valet switch in my truck and was wondering were you guys got the parts for this and about how much it was i read the sticky and it seems easy enough to acomplish in a afternoon

Mine came from a truck parts store, also check hydraulic shops since most of them carry a good line of Parker stuff.

wat about for the on off solenoid

What, pray tell, is a valet switch, and what is it's purpose.

Thanks for indulging my ignorance.

...thanks BK, ...I was wondering the same thing. The sticky told me how, but not why, ...

the way i understand it is that it cuts the vacum supply off to the pump so you dont use as much fuel beacuase the pump doesnt think there is no boost but i may be wrong...

A valet switch controls a solenoid valve in the boost line to the AFC housing. When the valve is closed, no boost gets to the AFC, so none of the monkey motion with the fuel pin happens, which limits fueling quite a bit. Mine pulls about 70 HP out of the truck, and keeps the EGT gauge below 1200 no matter what. It's a good way to have a dual purpose tow rig/play truck.

I knew that there was a valet for the p pump but not for the ve. This sounds like a really good idea. I have always wondered about having the best of both worlds power when needed but being able to back it off aswell. I was wondering if it would be possible to, instead of totally block the AFC line, put in a threaded valve (similar to boost elbow) to allow for precise boost control. Then you cold dial in the power with an infinite range.

hmm.
I didn't know that was exactly what the switch did. A while ago, I used to have something like this and reasoned that it must decrease fuel and give better mileage and now I'm glad to see that I was right. When I installed my fuel plate I put the new boost fitting with the smaller hole on the AFC housing, b/c the instructions for that part didn't match my truck and I wasn't sure what to do. That made it so it took longer for the boost to build in the AFU housing. The smaller hole didn't make that much of a noticeable difference since I've put the original fitting back on, but I think it probably helped with fuel efficiency a little.

Before I put the original fitting back on, the boost line the AFC housing came undone because I had it all rigged up at the time due to having the wrong parts. It had worked for a long time, but when it came undone the difference was huge. The AFC housing didn't see any boost thus there was a dramatic fuel decrease. The acceleration was very slow.

It's not as dramatic on a 1st gen. My truck makes around 280 HP in valet mode, which is still pretty entertaining.
