Mechanical Fuel Pump Kits

All,

Was doing some digging on fuel pumps for another member and thought this would be useful from a conversation with RP 8 years ago….. I’m getting old


RP - 2006
I set to work using the fuel pump kits you so kindly procured for me. As stated the kits were for '68.5 - '73 G60s, so I had a collection of that style fuel pump set aside for this rebuild jamboree. From the start of the very first one, things didn't look right. The difference between the early pumps and the post '68.5 pumps is the length of the lower cylinder on the bottom body half: the early pumps are a length of about 1 1/2 inches, while the later pumps are a shorter measure.

The problem I found with the kits is that the 'stem' on the diaphragm is 2" long, while the 'stem' on the later pumps is about 1 1/2 inches long. So, I tear apart one of the early pumps (this one is so early it actually has a priming pump handle on it) and voila! - the diaphragm stems are the same length! I also had a Goss fuel pump kit I had got from Ebay a while back (Goss kit # 919KT) which stated that it suited '68 - '73 G60. This kit was identical to the kits you sent.

So, it turns out that the kits you procured actually fit our earlier Patrols, which means I am: a) short on the kits I got from you, and b) still need to find the kits for the later pumps.

John - 67L60 obtained a Goss fuel pump kit from Ebay, kit # 810KT. From the pictures he sent me of his rebuild process, it appears that this Goss kit suits what we have for the later fuel pump.

Ultimately, what I was hoping was that you might find a source for both of these Goss fuel pump kits - 810KT and 919KT. I would especially love to know the length of the diaphragm stem on the 810KT kit. Then order up a few of each kit.


Swerve - 2006
I confirmed “The 919KT is no longer produced and not available. The 810KT is still available and the diaphragm length is 1" and 3/4. It also has a T piece whatever that is"


RP - 2006
This means that the 919KT is indeed the same as the Nissan 17010-58026 kits. Both kits are in very limited supply, even in your end of the world.

This also means that the 810KT is indeed the kit needed for the/our '68 and later fuel pumps. I just took one apart and measured the stem, and it is very close to 1 3/4 inches.




NEXT POINT – Any kit in now difficult to locate in Oz, When I last bought stock, I cleaned out all old stock I had available. You will find some places have old stock sitting on shelves, but you need to find who and where they are. SO before a flood of people start asking me, I don’t know where any kits are.

HAHAHA that was a nice tease, Steve...

Here's all the information and part numbers you need to rebuild your fuel pump...


Oh, By the way, none of these parts are available anymore :violin:

The thing is they are around. You need to call various suppliers and ask ? But you need to know what your talking about.

I just started to explore fuel pump rebuild kits and have come to exactly conclusion to Swerve. That is they are not available.

It looks like there are several types of fuel pumps. Pre 68 and post 68. I'm after the post 68 type.

GOSS did have the 810KT rebuild kit but its no longer available. It is on GOSS's 'internal' catalogue and on some resellers web sites but there's none available. I have emailed GOSS to see if they can help me ..... but I'm not holding my breath!

I also contacted NOW AND THEN in the US. They responded that if I send pictures and measurements then they may be able to help. So before I go to all that trouble has anyone else got a rebuild kit from Now & Then? I know some members have had the fuel pump rebuilt by them.

Anyone willing to send a fuel pump to Now and Then for them to work out the parts I need? That way we might be able to get them to be a source of rebuild kits in the future.

Also is it possible to just replace the diaphrame and use the existing metal stem? Is that what rebuild shops do? So far I haven't been able to find a fuel pump rebuilder - although I haven't tried too hard.

In the meantime I guess I'll just use an electric fuel pump.
Not sure if I will get there.

Now and Then would rebuild your pump if you sent it to them.

It isn't possible to replace just the diaphragm. The way it is attached to the stem makes it impossible to remove without destroying it.

I just sent mine to Now and Then and they did an amazing job. Quick turn around and for $109 I practically have a new pump.

I found a replacement mechanical fuel pump.

Goss G635.jpg


It is a Goss G635 (see goss.com.au).

It fits a Nissan Urvan 2.0 (E23).

On a recommendation of my friendly mechanic I look my existing leaky pump to a guy who has been repairing diesel fuel pumps for decades. He couldn't get parts but not to be defeated he researched the market, ordered a few pumps and worked out which one might work. Its called old time service!

I fitted it today. It lined up perfectly with the bolt pattern. The in and out pipes are smaller 6mm instead of 8mm. So it required a bit if reworking the in and out hoses. The smaller diameter of pipes doesn't seem to cause issues although early days yet!

But the end result is that it works! It came with two gaskets and an insulator. The rocker arm is slightly different but approx the same.

Cost was about $250 AUD

I have been talking to Now and Then. I will see if they can supply me just the diaphragm. Most other parts seemed to be available in Oz.

Hey friend, do u have an update on how this goss fuel pump has worked out for you? Started up my patrol this morning and my fuel pump was leaking like a siv... Didn't take it apart yet but it's leaking from the body somewhere, guessing a diaphragm or gasket went out. I'd like to pick a new mechanical one up. How has yours held up?

The fuel pump can be interchanged though out all the years, including the P40 engine also.

I have this info saved:

Fuel pump part number: 17010-L6200
copy this into the search field here:

$148 (Aug-2018)

Another fork lift parts store with a better price:

There's also a repair kit on eBay
https://www.ebay.com/itm/NISSAN-PATROL- ... ah&vxp=mtr

Please take into account that Nissan changed the fuel pump at least 3 times. Only minor changes (probably driven by the accountants) but one of those changes was the length of the leg of the diaphragm. The eBay kit might be correct for some years but not for others. It's possible that it will work on your pump. Impossible

Esteban, thank you very much! A few good looking options. I have the 69 p motor, from other forums seems like the diaphragm stem length might be a little too long for mine. Now and then quoted me for about $120 rebuilt. Will look into these, thanks a bunch for the quick reply. Now i have an idea why i ran out of gas on the side of the highway on monday :) Thought i was just getting horrible gas mileage :P

Check you engine oil level and condition. Maybe part of the fuel ended up there.

Happened to me once.

The Goss G635 worked well. The smaller outlets didn't seem to cause any issues.

I have since found some repair kits to the old pump. I prefer to have 'original' fittings so I have purchased two different repair kits. I have fitted one and hence have the G635 as a spare.

These repair kits are NAPCO 71-0185 and NAPCO 71-0430. Both purchased on ebay. Hopefully available in the USA somewhere. The leg of the diaphragm is about 2inches.

The kits contain all you need to repair the pump. One contained screws to hold the housing together. I found the spring a bit long and didn't use it.

I have a 66 with the primer on the pump. Is the rebuild kit for that pump different? What part number should I be searching for?

Thanks!

If you have the pump with the primer, it should have the 2" diaphragm leg. It seems from Peter60's post that the NAPCO 71-0185 kit should work for you.
