2nd Gen Non-Engine/Transmission How do you tap your fuel tank for new larger fuel lines?

[TomGolden]

Hi all,



I would very much like to upgrade my entire fuel system, from the

tank all the way up to the VP44 with larger diameter lines, an

aftermarket pump, new fuel filter, etc. . My biggest puzzle is how

to tap into my fuel tank to attach the new lines. I don't want to

just tie into the existing 3/8" line, I want to make use of the

larger diameter of the -AN lines.



I have the TransferFlow 54 gallon OEM replacement tank.



I will be using either -AN8 or -AN10 lines (a Ford buddy is buying

a 50' roll of the Aeroquip -AN10 socketless line, and I may split

the cost with him).



I do not think just drilling and tapping the lower side or bottom of

the tank would be good enough, I'm afraid it would leak very

soon if not instantly. Anyone who has done this, your feedback

would be most appreciated.



Thanks,

Tom

Never done this to a CTD but...



How about a gas tank repair shop. They should be able to add the larger fuel line ports safely and leak free.

www.smokindiesel.com Call and talk to Doug, he has two versions of line to use.

BTW, when I measured my factory fuel lines, they were 1/4", not 3/8".

Tom, I did mine like Rob Thomas. . . drilled through the pickup assembly cap. Removed the bed to get to it (that was the 2nd and 3rd time I tore it apart, the first time I dropped the tank).



I used a -8AN bulkhead mount to install in the cap, and ran a stiff flexible clear hose to the bottom and cut a hole there (in the bottom of the pickup assembly that is) and then attached a brass flare piece with notches cut in the edge of it so it could be pressed against the bottom of the tank and pull in fuel from the sides. I made the hose a bit longer than needed so it would have springiness to press against the bottom of the tank. I removed the stock filtering screen and the antisiphon/air entrapment contraption in the bottom of the pickup.

PS I found the easiest access was by unbolting the bed then sliding it rearward on the frame about 2-2. 5 feet until you could reach the pickup assy. from above.
