Pat, largely thanks to all your help, you're FJ Yoda!

Eric...See how helpful that turned out? Good on ya...that's what makes this forum work.

Steve, FYI the float needle seats are what's different between the gravity flow carbs and the fuel pump carbs.
They have a smaller opening on the fuel pump carbs (vs. gravity flow) due to the higher line pressure.
The gravity flow carbs have float needle seats that have a larger opening, lower line pressure.
If you try and use the gravity flow needle seats on a fuel pump application, the high line pressure from the fuel pump will push the gravity flow needle away from the seat and flooding will occur.

Just let Randy know you're switching to uni-pods and he can make the necessary adjustments to your carb when you send it to him for the rebuild. Typically a shim needs to be added enrich the fuel a bit to address the added air flow from the uni filters.

I like the golan fuel filter because it has 10 micron filtering which was the best I could find. But I still also run the normal yamaha pre-filter which I think is 40 micron to catch the bigger stuff before fuel hits the golan filter after the pump.

In addition to the converting from gravity flow to a fuel pump, the airbox will be removed and replaced by UNI style filters.

Not really an FJ specific vendor, but https://twistedthrottle.com/ is closing up shop.  Lots of closeout and discounts on their website.

Steve,
You might want a clear fuel filter, so you can see fuel flowing and any collected dirt. These have 1/4" and 5/16" hose barbs.
in-line fuel filter 1
in-line fuel filter 2
.

I just tried to upload part 1 and part 2 of the fuel pump conversion let's see if this works.

I converted my 86 to have a fuel pump. I made a post and there are two PDF documents you can download that I put together. I was unable to upload it in one document since it was too large so broke it down into two.

I'm happy with the conversion and have not had any issues after nearly 2,000 miles.

In addition to running the normal fuel filter between the tank and fuel pump I also suggest running the Golan fuel filter between the pump and carbs to help protect your newly cleaned carbs from any contaminants.
