Yeah, I found that site a few weeks back when I first heard about my truck. Actually found that site before this one. Great site. Thanks for looking out.

Nah, I'll be switching to 5x5 lugs and front discs when I do the air ride. Better selectoin of wheel too.

We tried to get the motor running yesterday but it would either rev up after start and then quit or it would idle for a minute and quit or die if you gave it any throttle. So today I ordered all the parts (hopefully) to swap the stock carb for a Holley 500.

The PO was having the same problem and replaced the fuel pump, points and cap, drained the tank and filled it with fresh fuel and rebuilt the stock carb but it didn't help.We will probably do a compression test before doing the carb swap. Fingers crossed...

Accelerator pump's duff by the sound of it.

To fix it, remove the original carb, hold it in your right hand, throw into scrap pile and fit Holley 4412.

Easy conversion and does wonders for your power output and gas mileage. you need to find a new air filter housing, though; I used one from a 70's Chevy.

Everything you need to know on this is on the 6066 site. Some advocate the Powertronix set-up but mine runs just fine on the OEM setup.

[creep]

That's what I ordered. Got a Holley 4412s, adapter plate, air cleaner assembly, fittings, throttle return spring kit and an in line fuel filter. The wait is killin' me, I wanna drive it some before we tear it apart.

[creep]

Santa came by a little early today...








Adapter plate is on backorder. I have to wait an agonizing two weeks to plop that sucker on the 305.

Very nice goodies - but be careful with that fuel filter.....

OUCH! How did that happen?

Fuel leak. Don't know if it was due to glass type filter - but after I finish my run-in of my new '283' I'm going back to the polished canister type, because there was a lot of talk at the time about those things being dangerous if you're not damn sure they're tied down - to keep them from cracking against any metal parts on your engine.

[MacAttack]

I went with this one - just below my fuel tank - outside the cab, and I'm going to take the glass one off that's in the engine compartment, shortly - to avoid this......

[creep]

Thanks for the tip! I went with the glass style because we are still trying to get the 305 to run and wanted to be able to see how well it was pumping the gas to the carb. Now I will probably replace it with a metal one after we get it running.

[MacAttack]

That's precisely what I did - made sure of fuel flow and let the glass one collect and crap from the tank. This weekend I'll go solid rubber hose in the engine compartment - just one place less (with two clamps) to spray the engine down with fuel.

Mac.

[creep]

Sounds like a good Idea. I was thinking about going all rubber hose in the engine bay.
I actually found a carb adapter locally so the carb swap might be happening this weekend.

[MacAttack]

Outstanding!

On the single piece in the engine bay - that's the way I'm going: from the hard metal line on the frame rail - right to the carb. What surprised me was the filter by the tank didn't cause any fuel starving problems. Works perfectly.

I'll keep the clear glass filter unit in my tool box for other motor break-ins or diagnosing any carb problems later on, but I'm not leaving it on the new engine.

Mac.

nice stuff creep........congrats.

I'd not do the big length of rubber hose. In the last 10 years, with different modern gas, I see my fuel hoses drying out and getting cracks within a year or two at best. I've got to where I run steel line everywhere but where absolutely necessary to run rubber hose.

[creep]

Is it necessary to flare the end of the hardline where the rubber hose attaches? I've never messed with fuel lines before but it seems like a good idea for a better seal.

[Tx Firefighter]

I do it. You can use any tubing flare tool to slightly enlarge the end of the tube. Not a full flare, just swell it to give the clamp some grip.

[creep]

That's what I figured. Thanks.

[creep]

I ordered my air ride setup today. I went with a ***************** P-51 crossmember combo kit, rear wishbone superlift kit and a complete air management kit. It's gonna be about a month before it all shows up at my door. Waiting sucks!

[creep]

Got the carb on today but it's still doing the same thing. The glass filter doesn't stay filled with gas when we try to start it which leaves us to believe there is a problem with the fuel pump. It has an electric fuel pump on the frame under the passenger side of the seat and the stock fuel pump is bypassed. We're going to put a meter on it to see if it's geting enough juice. If it's getting 12v we will try switching the pump.

The carb swap was pretty easy except there was some sort of plastic spacer stuck to the intake manifold. It wouldn't come off easily so instead of risking damage to the manifold I just bought longer bolts and put the adapter plate on over the spacer. The choke cable wasn't quite long enough either.

I'll have some pics up later tomorrow.

[creep]

Here's the stock (I think) setup...

This is the plastic spacer stuck to the manifold...

The adapter plate bolted to the manifold...

and the Holley installed and plumbed...

and the throttle return spring mount kit...

I had to get longer bolts to mount the adapter to the manifold because of the spacer and 1 longer bolt for the front driver's side carb mount to attach the sring mount.

Man, I really need to clean that motor up some!

[creep]

We finally got it running this weekend. Replaced the cheap @$$ fuel pump with a Holley "Red" from my buddy's Datsun and ran it from a gas can and it cranked right up and ran great. When we hooked it back up to the tank it had problems getting gas. We took the sending unit out and ran a hose from the hard line into the tank and it ran again so we thought it was the sending unit. I put the sending unit back into the tank and hooked it all back up and tried it again and it ran great. So I ordered a new fuel pump from summit Racing and a new sending unit and taillight parts from Classic Parts.

I was also going to install some new parklamp lenses but they have a rivet thing to secure them to the housing and I'm not quite sure how to install them. They have a solid head with a short, narrow, hollow shaft. anyone know what I'm talking about?

[4dranch]

congrats on getting it running...

Ooh and the lens are real easy, just remember the rivets are soft. check out my thread page 13 post #304.
