Clutch kit that worked on my late '68 J13...

 

#06-020

 

Rock catalog says it's for '68-73 510 w/L16.  Rock catalog shows #06-019 as "correct" for my J13.  Not sure what, if any, difference there is between the two.

Thanks. Some PO must have decided on diaphragm when he replaced the one on my truck some time around 1982.

Just bought a '66 520. Previous owner installed an electric fuel pump, recommended getting a new mechanical pump.

 

Are the J15 fuel pumps interchangable with the J13's? 

 

They look the same but wanted to make sure.

Probably, but we didn't get J15s north of Mexico. (maybe a fork lift engine?)

 

Nothing wrong with electric as long as fuel pressure is not much over 3 PSI. If it works, leave it, if it floods, maybe a cheap fuel pressure regulator.

Just seeing a lot of cheaper J15 replacements on eBay and not a lot of J13 options that don't break the bank comparatively.

 

I'll keep that in mind, it does work. At around 1 PSI. Its just loud as hell and kinda patched in there a little wonky. Might have to redo wiring so it'd be nice to delete it and go the mechanical fuel pump route.

There are a lot of quiet electric fuel pumps out there that don't have a shitload of pressure, most work best back at the tank, they push fuel better than they pull fuel.

I am using one right now that I bought back in the 90s, but it has starting to quit working for no reason every once in a while in the worst places, but I jump out with my screw driver and get on my back, crawl under the truck, tap on it and it starts working again, so they do not last forever.

I stumbled onto a thread (here, I think... search isn't cooperating with me at the moment) some time back that had side-by-side pics of the several different fuel pumps of the era. They all seemed functionally equivalent, except for the different pump arms. IIRC, the poster was swapping arms from a bad pump to a new one (probably from one of the several ebay sellers).

Try typing what you want into Google and then put Ratsun at the end. If you know the title even better.

Here's Mike K talking about swapping arms. I'm pretty sure there is more discussion on doing this elsewhere

So I got the Pierce Manifolds 32/36 DGEV Weber conversion kit and I had a quick, newbie question about the intake.

 

There's a threaded hole on the intake manifold and I'm wondering what its for? First thought was for a bung for vacuum or something. I checked out the stock 520 intake manifold and theres a similar hole, but it just has a nut screwed into it. Any ideas? Letting my true new jack flag fly, go easy on me lol.

It's a vacuum hole if you need it for something (power brakes, PCV, etc). Otherwise, it's a hole that needs plugging.
