Libarata Posted November 15, 2019 Share Posted November 15, 2019 So, here we have my 1984 XL rwd 302cid in bright copper glow body with polar white cap. I just put her 85,000th mile on her yesterday! She needs a fuel selector valve, carb tune/clean, new fuel sending units, the rear tank to be cleaned, fuel filters, all around new fluids, and rubber stuff on everything.

Libarata Posted November 15, 2019 Author Share Posted November 15, 2019 So, right off the bat, I have a bit of confusion. I ordered the new fuel switch valve thing, and the one shipped to me is completely different! Is the one on the truck from a bronco? That is the closest I could fin on google.

Rembrant Posted November 15, 2019 Share Posted November 15, 2019 That's a nice straight looking truck! Love the color too. Link to comment Share on other sites More sharing options...

According to Ford's Master Parts Catalog (Documentation/Fuel Systems/Fuel System Part #'s/Fuel Tank Selector Valve), which I've copied in below, your truck should take E3TZ 9189-D, which is a 3-port valve. That was used with engines having mechanical fuel pumps. Does yours have a mechanical pump? If so then you should have one hose from each tank to the valve, and one hose from the valve to the pump.

So I assume a mechanical pump. No clue though, since I’m mechanically tarded. Doing a cursory google, it looks like I need to start hunting the graveyards around here for a replacement or three. Many thanks in that catalog number! Link to comment Share on other sites More sharing options...

Note that there are two numbers associated with every Ford part, but neither are "catalog numbers": Part Number: That's what E3TZ 9189-D is. And that's what you'd use to order a part from Ford. But, the part number is never put on the part itself. It is usually on the box though. ID or Engineering Number: This number that is on the part. And in the case of E3TZ 9189-D the ID # is E3TB 9F271-CA, which you can see in the right column. So when you go to the salvage you'll be looking for a part labeled E3TB 9F271-CA.

'84 is not into EFI yet, in '86 It was an option for the 302... Don't think there was an electric fuel pump for carbs then..... Link to comment Share on other sites More sharing options...

Didn't the 302 go to EFI mid-way through the 1985 model year, and then were all EFI in 1986? The feedback carbs add a little more confusion. Did all carbed models come with feedback carbs after a certain date, like sometime in 1983?...or did that vary by state and/or region? Link to comment Share on other sites More sharing options...

Quite possibly the 85's may have had the option, I know the '86 302 had the option of EFI cause that's what I picked on mine at the time, and picking it up at the dealer (Patalano ford in Franklin MA) I remember a BIG yellow warning card hanging off the rear view mirror stating, "This vehicle is equipped with fuel injection, DO NOT pump the accelerator pedal before starting" Ahhh, those were the days.....

Libarata Posted January 3, 2020 Author Share Posted January 3, 2020 Update time! So, I had a chugging issue, every time I accelerated, turned, or went uphill. I added seafoam to a full tank, and towards the end of the tank, my suspicions were proven. The fuel filter was just FULL of varnish and chunks. Cleaned the carb as well as possible without removing her, removed the irl filter(can’t find replacement locally). And decided it was time to tackle this tank selecting issue once and for all... my neighbor and I spent all day at a backwoods salvage yard crawling under dual tank fords with absolutely no luck. This must be an after market, or oem one off from the factory... In the end, we wisened up and tested the valve on the truck, only to find out that it actually worked. So we dropped the rear tank, new fuel sending unit, filled with fresh gas, and off we went! The next time on the agenda, is the oem screw in filter, and an auxiliary inline filter to help with all the old gas and chunks. Oh, and weather stripping...
