PETCOCKS:


OEM Fuel petcocks: note that although these will physically bolt up to your tank, some versions are completely different from your original petcock in every way imaginable!


fp16) OEM Yamaha replacement Complete Fuel Petcock. Brand new unit comes complete with the internal filter. This unit fits and looks "somewhat" the same as an original XJ-series petcock, but it is a completely new unit and no component (internal) parts will interchange between an original petcock and these units. Surprisingly, these units are still made by the Taiyo Giken Company, who supplied the original petcocks on the XJ era bikes....

HCP626 OEM Complete Fuel Petcock. The vacuum and fuel outlet port nipples point straight out towards the back of the bike (parallel to the front-to-back centerline of the bike). This is the most useful orientation for these outlet pipes, and the same as on original XJ petcocks. Includes the in-tank filters and the petcock-to-tank sealing o-ring. Fits all XJ550/650 (except Turbo) and all XJ750 models. NOTE: petcock mounting screws and their washers are NOT included!
$ 79.00


HCP625 OEM Complete Fuel Petcock. The vacuum outlet port nipple points directly out towards the back of the bike, while the fuel outlet port nipple faces backwards and at a 45-degree angle outwards. This is a slightly odd orientation, but it does allow for slightly more space for the fuel line to be routed clear of obstructions, especially when using an aftermarket in-line fuel filter. Includes the in-tank filter and the petcock-to-tank sealing o-ring. Fits all XJ550/650 (except Turbo) and 750 models. NOTE: petcock mounting screws and their washers are NOT included!
$ 65.00


HCP627 OEM Complete Fuel Petcock. The fuel inlet and outlet port nipples point directly out towards the back of the bike and tilted upwards at a 45-degree angle. Includes the in-tank filters and the petcock-to-tank sealing o-ring. Fits all XJ650 Turbo models. NOTE: petcock mounting screws and their washers are NOT included!
$ 118.00


HCP628 OEM Complete Fuel Petcock. The vacuum port nipple points directly out towards the back of the bike (rather than being angled as the original) and the fuel inlet port nipple is tilted upwards at about a 45-degree angle and is NOT angled towards the center of the bike (as original), nor is the fuel inlet nipple as long as on an original petcock. Surprisingly, besides these minor differences, these petcocks look exactly the the originals. Also, the changed inlet pipe orientation results in being able to install the rear petcock-to-tank mounting screw easily---on original petcocks, you basically have to almost hacksaw the screw off to remove/replace it or the fiber sealing washer! (a wonderful feat of factory engineering!). Includes the in-tank filter and the petcock-to-tank sealing o-ring. Fits all XJ700 and XJ900RK models. NOTE: petcock mounting screws and their washers are NOT included!
$ 91.00

fp17) Aftermarket Complete ON-OFF-RES FUEL VALVE. Not really a "petcock" in the XJ sense of the word. Yamaha designed their petcocks to be a very clever "automatic" fuel supply valve, meaning it has to have engine vacuum for it to function. Great idea (when it works) because it allows us to basically "set it and forget it". Bad news is that when the seals go bad, or as age wears the internal components, it can become a really bad idea, since it will leak fuel into the carbs when it's not supposed to, leading to flooded carbs, fuel in the crankcase, spun bearings, etc.

This true fuel VALVE is either ON (in either the standard "ON" or the "RES"erve positions) or it's OFF. And it doesn't depend on engine vacuum, just gravity. So it won't ever leak or pass fuel in the OFF position. That's the good news. The bad news is that you have to remember to turn it on or off manually (as in every time you start your bike up or shut it down) or, instead of blaming a faulty petcock for your resultant problems, you'll have to blame yourself!

Once installed, this unit fits and looks somewhat the same as an original XJ-series petcock, what with the chrome faceplate and selector lever. It obviously has no vacuum nipple, only a rear-ward facing fuel outlet, which means you will need to remove your petcock vacuum line from the #3 intake manifold boot nipple and replace it with a rubber block-off cap plug. This fuel valve uses the same size fuel line as original.

You also must use a adapter plate on the bottom of your fuel tank that this fuel valve screws into, and the brass-mesh, in-tank fuel filter (included with this valve) is actually larger than the opening in the bottom of the gas tank (just ever so slightly), so you'll have to grind the tank opening with a dremel tool or steel file to allow the filter to go into the opening. Our complete HCP630SET (below) includes a bolt-on grinding template so you'll know exactly how much metal to remove.

All-in-all, this is a both a great value and a fine idea. It forever eliminates the dreaded "leaking petcock" problems associated with 20+ year old factory petcocks for a price just slightly more than what it costs to rebuild a factory petcock. On the downside, you will have to remember to turn this unit off or on every single time! And, once you modify your tank (by enlarging the petcock opening), an original petcock will never seal up properly to it again (or, not without alot of effort on your part to "shrink" the enlarged hole!).

rp3) Aftermarket Mini In-Line Fuel On-Off Valve. This 1/4" inlet/outlet fuel shutoff valve provides a fail-safe solution for leaky petcocks. Small size allows it to easily fit under the gas tank, within the petcock-to-carb fuel line. Lever handle can be set to full on or full off position. Best solution is to repair or replace a leaky petcock, but for a quick and easy solution, this valve will do the job.

t1) Aftermarket petcock tank opening Painting Block-off Plate & Gasket----a die-cut thin aluminum plate and matching rubber gasket, exactly the same size as the petcock-to-tank top mounting flange (or "face").

Before tank paint stripping or during actual tank painting, you'll remove your petcock and replace it with this plate, and therefore won't paint the oval petcock mounting area on the tank (which you definetly don't want to do---it should be bare metal for a proper seal). Includes a pair of mounting screws also, so you don't have to paint over your original or new petcock-to-tank mounting screws, either.

Of course, this block-off plate also works great when performing an electrolytic cleaning of the tank, since you really DON'T want to leave your petcock in the tank when performing such a process!

HCP634SET petcock block-off plate and gasket set. Fits all XJ550/650 (except Turbo)/750 tanks.
$ 6.00


t2) Aftermarket tank fuel sender opening Painting Block-off Plate & Gasket----a die-cut thin plastic plate and matching rubber gasket, exactly the same size as the petcock-to-tank top mounting flange (or "face").

Before tank paint stripping or during actual tank painting, you'll remove your fuel sending unit and replace it with this plate, and therefore won't paint the sender mounting area on the tank (which you definetly don't want to do---it should be bare metal for a proper seal). Includes a set of four mounting screws also, so you don't have to paint over your original or new sender-to-tank mounting screws, either.

Of course, this block-off plate also works great when performing an electrolytic cleaning of the tank, since you really DON'T want to leave your sending unit in the tank when performing such a process!

HCP2738SET fuel sending unit block-off plate and gasket set. Fits all XJ550 Seca, XJ750 Seca & Maxim (1982), and XJ1100 tanks.
