Shop VACUUM HOSE TRICK

Vacuum Hose Trick on Small Fittings

There is one vacuum fitting in particular on the 951 that has a smaller than normal diameter nipple and no bead roll or enlargement at the end to keep the vacuum hose from pulling off easily or blowing off under boost. It's the steel tube fitting out the side of the metal fuel vapor diaphragm.

Although the 944 NA and 968 use the same parts, they don't go under boost so it's less of an issue on those models. However you could use this fix on any vacuum connection on any model.

Even installing a small zip or wire tie doesn't keep the hose from coming off easily. So for this, we are showing you a trick we recently came up with that fixes the problem, and does it in such a clean way, you may decide to do all your connections this way.

We are going to install a piece of 1/4" ID silicone hose over our standard vacuum hose. This does two things. It makes the ID smaller on the vacuum hose, and puts a lot more stretch or tension on the hose to make it a very snug fit and difficult to pull off.

A) Here you see the finished product which is a double wall vacuum connection on the problematic metal fuel vapor diaphragm.

B) On the left is a 1" long piece of 1/4" ID silicone hose. On the right is our standard .100" wall vacuum hose.

C) We slip the 1" long piece of 1/4" hose over the ends of a pair of needle nose pliers.

D) Pulling the handles apart to stretch the hose, slip a bolt or object between the jaws to keep them separated. This will in effect lock the pliers into position allowing you to work with the vacuum hose. The stretching of the 1/4" hose holds the bolt in place.

E) Slip the standard vacuum hose into the stretched 1/4" hose. A little twisting motion may be required to get it in and through. Let it protrude out the other side.

TIP: Next step cannot be explained in a picture real well. Once the hose is through, pull the pliers handles apart a little more to loosen up on the bolt or object. Then allow the object to more forward on the pliers toward the hoses then release the handles again. You can see in picture E the bolt is closer to the hose than in picture (D).

This lowers the stretch or tension on the hoses. At this point, it's much easier to slip the dual wall hose assembly off the end of the pliers.

F) Now you have a double wall hose assembly! If it's oblong, pinch the hose while you roll it between your fingers.

G) Using a razor blade or similar, trim off the excess hose to give you the length you desire for your connection and you get a nice clean edge or end to the assembly.

H) Here you see a the vacuum connection on a remote fuel regulator. We used black over red hose here. You can stick with the same color hose as in picture (A), or mix them up. It depends on the look you want. You can trim the length to fit the particular vacuum nipple you are connecting to. Longer fitting, longer double wall. Shorter fitting, shorter double wall.

Since the inner hose is being squeezed, the ID will get smaller. We feel you should not have the double wall portion any longer than the nipple you're connecting to. A little less is even better.

We sell 1/4" hose by the foot and will be adding that as a option on our vacuum hose kits in the shopping cart. We may even start to include it as part of the kit if this suggestion gets popular.

We feel this is much cleaner then using zip ties and you don't have to cut and replace the ties when doing maintenance on your car requiring you to remove hoses.

The standard vacuum hose is a nice snug fit on all the fittings, but the metal fuel vapor diaphragm was the main reason for this remedy.

Many of you zip tie everything anyway. Now you have a new method to try.

INTERNATIONAL ORDERING



TO OUR INTERNATIONAL CUSTOMERS:


In the past, we have used a separate order form for placing International orders. We have quit using that process and are requiring all customer to use the shopping cart system built into the web site and it's check out process.

If you simply want a quotation and are not ready to place an order, then cut and paste the contents of your shopping basket, take a screen shot of the basket, or make a list of items and send us a email requesting a quotation with shipping.

If you need shipping prices before you make your final decision to purchase, then you should request that quotation by email and not use the shopping cart checkout process because you will be paying for the parts at that time.

Since our shopping cart and shipping estimator will "NOT" correctly calculate shipping charges on International Orders, we have it set-up to where the shipping will be Zero Dollars ($0.00) when checking out. When the shopping carts address process learns you are not in the United States by selecting your particular country, that's when it switches to equal Zero. That does NOT mean shipping is free.

Upon completion of the check out process, you will have paid for your parts but NOT the shipping on those parts.

Once we look over your parts ordered and calculate shipping weights and box sizes, we will send you an E-Mail with at least one shipping option and maybe several. We utilize UPS, DHL and the United States Postal Service (USPS) to deliver your parts.

Once you pick a shipping carrier and agree to the quotation by returning the E-Mail, we will be sending a PayPal money request for the amount of the shipping to be collected. If the parts are expected to be shipping out quickly, then you may receive that email quickly. If the parts are going to need to be built or something is on back order from the list of parts, we may hold off sending that E-Mail until we have the shipment ready to go. It can vary from order to order as to how we do that. If you think you should be hearing from us quickly, but you don't, feel free to contact us.

If you have special shipping needs or requirements, during the checkout you will see a SPECIAL ORDER INSTRUCTIONS window. Enter that special information there.

A good bit of our business is International and we have been taking care of those valued customers since 1999.
