FREQUENCY VALVE REBUILD SERVICE (WITH 102400A BRAIDED STAINLESS LINE)

UPDATED!

In 2023, we switched our rebuild process from all stainless lines, to a nylon low pressure line, and a stainless high pressure line. The reason for this change is due to the high number of frequency valve failures we were seeing as a result of the normal crimping action involved in attaching the stainless braided line onto the low pressure side of the frequency valve. When this failure occurs, the frequency valve no longer sprays and cannot be repaired - even if the added stainless line was subsequently removed. Frequency valves are becoming increasingly rare and their value is increasing correspondingly. We did not want to continue to place these precious and vital parts at risk of complete failure by continuing to crimp on a stainless steel braided line. We have arrived at what we feel is the only solution - rebuilding with a combination of new original-specification material for the low pressure side, and continuing to use upgraded braided stainless line for the high pressure side.

On all rebuilds, the original nylon does need to be replaced due to its age. Nylon is the OEM-specified material and the only proper choice for the original frequency valve on the low pressure side, where it must be pressed on. We renew the low pressure side of the frequency valve with a new nylon line meeting modern fuel specifications. The original nylon lasted for decades, and by replacing it with this new nylon line we expect similar longevity. If it is in good shape, the banjo fitting on the other end of this line is cleaned up and transferred from the customer’s original unit due to the scarcity of this component. If the customer’s banjo fitting is deemed too corroded or is damaged or missing, a separate core fee will be charged and a fitting from our small stock of cores will be used. Only the best banjo fitting cores are used, so we can ensure the highest quality rebuild possible. The high pressure line (part number 102400A), which is detachable, will continue to use the upgraded stainless steel braided hose with PTFE core. This gets us the best upgrade that we can offer, while not ruining any otherwise good frequency valves.
