Replacing Fuel Line 1975 20' CC

[Texascoastalfish]

Hi all,
Ive been in the process of getting my 75 re-powered and in doing so I discovered the fuel line coming to the "nipple" inside the Battery Box is cracking and brittle. This line goes all the way back to the tank. How Hard/Easy is it to replace the whole line ? Can I access it from under the CC ?
There is what appears to be access under the CC.
Thanks in Advance !

You should have an inspection plate under the console. The fuel line should be accessible inside. Generally it's secured with two hose clamps but because of the age, you might have to cut the line off. I would secure the "New Fuel Hose" to the old at the engine. Then pull the "Old Fuel Hose" thru the inspection plate with the new line following thru in tow.(a little Vasoline on the line helps.) Hopefully the line is free and not jammed up or secured with tight hose clamps along the way, whereas you might have to remove the deck hatch

Good Luck

Thanks Cap'n.
By inspection plate you mean the rather large hatch secured by
many screws directly under the console ? I wasn't sure if it extended all the way in front of the CC where there appears to be another access point. Just wanting to be sure I take off the correct hatch. Thanks again !

You shouldn't have to remove the screws, it should unscrew. The screws usually hold the outside frame down.

I had my guy remove the access hatch. It entailed completely removing the Console to open the tank coffin. He said its the heaviest Console he ever saw ( I'll take that as "Well Built" !) Upon inspection the Filler hose was pinched between and unused mounting ear and the edge of the coffin. So Im replacing the 1/1/2" helical fill hose as well as the 5/16 fuel line. He was amazed at the great condition of the tank and mentioned his 21 foot Mako had a foamed in tank and water has eaten up the tank and it was a nightmare. My 90 Johnson is mounted and running great ( after tearing carbs down due to Hurricane IKE induced mud. The Motor did get submerged after all. But we have been running it full of Sea Foam and fogged the cylinders. All looks good there. I have a replacement binnacle control box coming today and hopefully by this weekend it will be done. Also removed ALL old wiring and am running 2 hot and 2 ground wires from Battery to a fuse panel for my accessories. I will post pics when it is done. I want to get in on the Fall flounder run now in full swing. Its only money right?

Hey All,
I have finished Phase I of my Project. That was to Re Power to replace blown motor, Replace fuel Fill and motor main fuel line from tank, Install Fuse Box, Water Separator, Replace broken Binnacle Control Box, Throttle and Shift cables, Red Plug wiring harness, Bilge Pump, and steering Helm unit and cable. All went well EXCEPT that after remounting Console I was pulling old brittle wires out of the conduit and I pulled the Fuel Sender wire back into conduit...ARGGG ! I tried to fish it but havent been able to get it yet. Heres my question

Without removing Console again and accessing sender under the deck hatch how can I possibly retrieve the wire, and if I cant, would cutting a round access panel in the hatch to get to the sender be wise/stupid ? I would need to know WHERE the sender is located and cut my hole over it. I REALLY want a fuel gauge. Thanks in Advance !!

PS: Fr Frank and Bushwacker. You were right. That 90 HP Johnson pushed me 34-35. Plenty hole shot for me.

[Texascoastalfish]

Bump !! Anyone ?

I REALLY want a fuel gauge.

They really are not accurate. For Approx $125 go with a Northstar F210 Fuel Flow Monitor / Computer. It is easy to install and fits in the same mounting hole on the dash. You'll be glad you did

Here's a link to some shopping

I, too, use the Northstar fuel meter but mine is integrated with my GPS and/or depthsounder.

Fraction of the cost of Flo-scan products...

While you are at it I recommend replacing the fuel line also. I used goodyear SAEJ30R9 I think Item # is C-U-06-011
It is actually a fuel injection Hose, It has a dupont inner liner that is impervious to all of the fuels Diesel, Bio fuels, ethanol, alchohol and other blends. I am seeing alot of fuel line deterioration causing all kinds of problems. the fuel blends have solvents that are eating virtually everything. It is rediculously expensive, about 4 times more than regular fuel line. However that is a small price to pay when you consider a trip to the mechanic.
Before I was seeing a black powder in my filter, it was the previus fuel line deteriorating, immagine if that made it to the combustion chamber, the rings would have been toast. I didn't know I had a problen until I started getting fuel alarms.
