Chrisso 6 Posted December 12, 2019 Can anyone tell me what is missing from that hole on my mechanical fuel pump?!is it supposed to be a hole there or a gromet?fuel is pouring straight out and I can find a diagram anywhere to work it out Sent from my iPhone using Tapatalk Share this post Link to post Share on other sites
deankxf 20,288 Posted December 12, 2019 there's nothing meant to go in there. i suspect, like the waterpump hole, it's designed to let the fuel out(coolant on the water pump) when they fail.. you'd need a new fuel pump is My suspicion., lucky it's not going into the sump, infact, you should check your oil, if it's thin or higher than it was.. change it also because it will be contaminated with fuel and not as good with lubrication but can also cause other issues if so.@SPArKy_Dave will probably be able to confirm this 2 gerg and matt_lamb_160 reacted to this Share this post Link to post Share on other sites
Thom 6,651 Posted December 12, 2019 If fuel is coming out that hole it means you have a split diaphragm m, you either need a rebuild kit or a new fuel pump, and as Dean said, check you oil, you may have had fuel in the sump Sent from my SM-G973F using Tapatalk Share this post Link to post Share on other sites

Chrisso 6 Posted December 13, 2019 Hardly worth the hassle of even attempting to find rebuild kits for mechanical pumps these daysYeah I’ve had a look fuelmisor do a new one for $83 so I’ll probably just go with that, shit timing though as I was going to get the blue slip today oh well guess it can wait another week or 2Sent from my iPhone using Tapatalk 1 deankxf reacted to this Share this post Link to post Share on other sites

In my experience, the Goss aftermarket pumps are trouble. If you have an original fuel pump on there, I would always suggest to rebuild it (same for Alternator, starter etc). If the original one isn't there, then yeah, the Fuel Miser pumps are a direct copy (made in Korea, by Daewha Fuel pumps ltd), of the original Kirby pumps, https://daewha.en.ec21.com/ For anyone with a Goss pump, going back to factory (or fuel miser), you'll need to source an inverted flare fitting, for the carby hard-line. (I believe they're tapered 1/8 NPT, to 5/16 inverted flare) Goss pumps have the flare fitting in-built. Factory and fuel miser pumps have a separate brass fitting. 2 Thom and Chrisso reacted to this Share this post Link to post Share on other sites

Factory and fuel miser pumps have a separate brass fitting.It's more a matter of being able to find a kit even if you wanted to rebuild it.I've tried to find Holden 6 fuel pump kits before for customers at work, because originally they almost all had glass fuel bowls on the top, most aftermarket replacements don't so some people still want kits to keep them looking original.Near on impossible to find. Can't say I've tried for a Falcon one but I reckon they'd be just as difficult if not more 1 SPArKy_Dave reacted to this Share this post Link to post Share on other sites
SPArKy_Dave 8,873 Posted December 13, 2019 I'd be keen to see if the Daewha fuel pump diaphragm's are same as factory. If so, they may be available direct from Korea? Share this post Link to post Share on other sites
gerg 10,871 Posted December 13, 2019 I once had a mechanical pump shit itself on a Sunday arvo, had to call a mate to come rescue me.I had a Goss mechanical on my 302, the built-in barbs seemed to cause the body to bend really easily when tightening up the hose clamps. It just seemed cheap and tinny. Never failed, but I deleted it anyway and put in a Facet chunka-chunka pump just out of the tank. I like it because it gives a definite warning when fuel is getting low (by going chunka-chunka a lot louder than normal)Sent from my CPH1903 using Tapatalk 3 1 Slow250XC, bear351c, Ando81 and 1 other reacted to this Share this post Link to post Share on other sites
