Forum: My 74 has been a driveway ornament for a few years.
Got a note from local code enforcers to move it.

The last time I tried to start it, there was a fuel problem.
Only thing I could think of was a new fuel pump.
I finally got the new pump on, still no fuel in clear filter! WTF

While I am waiting for a better idea.
I will blow out lines w/compressor.

Help!

While waiting for someone to rescue me w/magic info.
I fired up the compressor and blew out the fuel line from FP to tank.
I also took a rag and tried to blow tank to FP.
Everything seems to be clear.

Now what? Eek
I think it might be time to call a Pro?

gasoline should flow from the tank pickup/sender to the inlet of the pump just by gravity with a full tank..
do you have gasoline at the inlet line to the pump?
You are sure you dont have a collapsed rubber line back at the tank?
Can you look into the tank with a flashlight and see the fuel sock at the end of the pickup?

Taijutsu

I agree 100%.
I checked the tank and the sock at the bottom.
There is fuel in the tank.

I have been thinking about the rubber fuel lines swelling from Ca blend fuel?
Not sure how to check that?
Any suggestions?

TIA

OK, I disconnected the rubber fuel ling where it connected to the bottom of the fuel tank.
NOTHING!
PERHAPS THE CLOG IS IN MY TANK?

How do I drain and check my tank?

If it is the tank.
Then I put in a new FP for nothing! eek

Suggestions please?

Fill up the carb with fuel. It takes a minute or two of running before the fuel pump will flow to the carb.

If you blew out the line it should free flow fuel to the pump. If it’s not you have a restriction or blockage in the line.

just read some of your post. How much fuel is in the tank? The pickup is not all the way on the bottom so you need a good 3” of fuel to be safe it’s covered. The way to drain the tank would be pump it out or remove the fuel sender.

Taijutsu

I have about a 1/4 tank.
The gauge works.

I'm thinking about pulling out the sender and pickup from the bottom of the tank.
Will hat allow me to clean out the stoppage?

I really don't want to drop the tank.

Taijutsu

Before I start a big job w/tank.
I'm wondering about using the compressor to blow out the 'tank blockage'
from below to see if that gets the fuel flowing?

If I remove the small cover for the fuel fitting and the sending unit.
Will that allow me to clean the pick up and clear the blockage?

This has been kicking my *** for some time now.
I would like to start driving my make me smile car! lol

Use your compressor- pull the hose off of the steel line just forward of the tank-- HAVE A CATCH CAN READY!! Use your compressor to blow the line from there back to the tank. Take the cap off the tank too. If the sock is clogged, that will blow the sock off the pickup tube.
Other than that, if you pull the sender and pickup, you will also drop what ever amount of fuel is in the tank.

Taijutsu

Thanks Tim: I need to siphon off a few gal first!
If cleaning the pickup solves my problem.
I can live w/that! OMG

The FP was more work than I would have believed.

I will keep the forum posted.

Thanks Everyone

You have to remove the rubber hose that is connected to the sender because it may have an internal collapse that is pushed open by the compressed air but then closes back up when there is no pressure.

Taijutsu

I removed the hose and blew out the fitting, nothing but air! WTF
I will remove the fitting and see if anything is wrong?
A good cleaning can't hurt?

I wonder if no fuel has been the problem all along?
I removed about a half gallon when the gauge was showing 1/4 tank.
I will clean out the sender and fuel fitting before I put in 5 gal of fresh fuel.

This has been such a disappointment for a long time now.
I am retired and it is time to get going!

This caused me two months of peril and about $300 on my 66'.....REPLACE THIS LINE!!!!!

Not a technical solution, but can you register it where it sits? CA is kinda funny, I know, but you might squeak by the SMOG inspection by a year.

Not that I intend to dissuade you from fixing your car properly of course! I have nothing to add that hasn't already been suggested. When you drop the tank, perhaps you will find an intact tank sticker.

Taijutsu

A line up into the tank?

TimAT

Yes. The rubber hoses used then are not real happy with the alcoholic gas of today. And old age sets in. They can fall apart inside and plug things up in one direction. (usually the ONE direction you need to be open)

Taijutsu

I will order the sending unit removal tool.
As long as I am in there, I might as well do this right! lol

Rick, one thing I would recommend whenever blowing out a fuel line in these cars is to lower the air pressure if you can to below 50 psi and closer to 25, at least initially. The lower pressure will probably answer your questions and even dislodge any minor obstructions, but not normally risk doing any damage to otherwise good hoses or lines.

Too much psi can do damage and even blow off or rupture a deteriorated hose creating at least a heck of a mess.

Good luck... GUSTO

Taijutsu

I have the pressure dialed down to #60 for my bike. lol

After too long on jack stands.
This is going to happen! eek

I appreciate all the support!

Jebby: Thanks for the advice.

How much of the rear tire carrier do I have to remove to get to the sending unit?

Anything else I need to know?




TIA
