Has anybody blown the hoses off of the vacuum block? Mine are so tight they don't need zip ties. I zip tied all of the rest of the connections. Before the zip ties, I blew off the hose at the check valve going to the charcoal canister. Anybody else ever do this?
If I remember correctly, around $150.00.
Fleet Pride sells the fittings and lines if you have one near youI have decided to go with push lock fittings coming out of the billet vacuum block. Could someone tell me the sizes for proper line size? The billet block I have now has 3 different size ports. I'm going to have to go with a different block but need proper line sizes. Running out of time to get this car back together before Bowling Green.:biggrin:
I do it a different way myself for a more cleaner look and run the vaccum lines from behind the motor.

pacecarta said:dont do a single 3/8 to all your vac , the pcv is a leak , the hvac is a draw , if you have vac brakes the brakes are a draw , all these can affect the true vacuum reading to important sensors like the map for alky or if you're runing speed density . fpr and other sensing devices like a hobbs for second pump, boost gauge etc
if you have vac brakes run them off a dedicated port , preferably a 3/8 ID source , i ran a 3/8 npt x -6 fitting and ran 6an braided hose to my vac booster and used a summit billet 6an check valve at the booster
same for the pcv , its a metered leak so anything tied to it wont read the true vacuum or be able to pull full vacuum
run it on its own port , an 1/8npt to 1/4" ID fitting should be fine
for maps hobbs , fuel regulator or boost gauge that dont move much air in their operation you can tie them together
hvac should also be seperated from others
i chose to just tap into the plenum and block off the stock location at top of throttle body
brakes are much improved over the billet vac block setup and with pushlock im not worried about important supply lines popping off
The black tubing is going to be 1/8 or 1/4. Typically the threads are going to be 1/8 npt.
I would suggest you use compression fittings, like the ones on the back of your boost gauge. That way the hose cannot "pop off".. example fuel pressure regulator.
On mine I had drilled out my fuel pressure reg to 1/16 npt, then used a 1/16 npt to -3 male adapter. Then ran -3 braided hose from the FPR to the block. This using SS braided hose. Fittings where nickel from XRP. I used a spacer from Champion and drilled the fittings into it.
3bar MAP, I cut of the ridge on its nipple and installed a compression fitting. Then adapted it to -3 and ran braided hose to it. Cannot be popped off
Overkill.. maybe so. The wrong hose pop's off at the end of a pass.. it ruins your day.. and the car can be done for a long time. Look at the brake booster connection.. that fitting is available at Summit.
Many ways this can be done. HTH
