Fuel Filler Neck

[AuroraGirl]

Is your filler like this or is it something different? If different I can snap a pic on my trucks derelict tank and try to identify what you speak of.

The picture is pretty blurry. Are you asking what my filler neck hose looks like or the metal part? I don't think I took a photo of the hose itself. It is very large compared to the gas one though. I took a metal part of a junkyard truck. My diesel neck is 2.25" at the metal part, 1.75" at the tank.

Is the filler hose the same for both sides? Looks like the vent hose is different.

Hey guys, I have an 87 K20 with an 83/83 dual tank bed on it. When trying to hook up the filler neck to the gas tank i ran into a problem. The fuel hose comes off the gas tank and tight into the support beam of the bed. if i bend it down out of the way it just kinks. From pictures online it looks like there were some metal pieces that the hoses connected to in between the fill neck and the fill hole on the tank. Any idea where i can get those? I know i need to get a small piece of preformed 45 degree fuel hose to come off the tank but have no idea where to get the 90 degree connection pipe from that to the filler neck.

LMC has all of the parts. It looks like 83 and 87 had different filler necks, but the rubber hoses were the same for both years.

I actually called and talked to LMC to ask them to measure the hoses for me. They won't fit. The one for the CUCV is huge. I am guessing they use the same filling hose as semis and other large trucks.

If it's just a diameter issue, I'd recommend finding someone with a parts truck and get two non-cucv filler necks. Any truck from 83-87 should do it for you... I can't imagine it would be more than $10-15 from a parts rig

The problem is at the tank as well. The actual metal inlet is bigger. The only one I've found is a used one from hillbillywizard.

Interesting... I'd still try and get it from a parts truck. I see full sets of dual tanks for dirt cheap around here. In fact I'll be pulling both of my 20 gallon tanks, fillers, fuel lines, and selector hardware in a month or so when I convert to a EFI blazer tank for my engine swap.

I'll buy a new filler neck, cap, and hose when I finally replace the gas tank with one made for EFI. I'm running an external fuel pump at the moment just to get it moving under it's own power.

If you turn the phone sideways you can but no one views it like that.

That’s the only way I view my phone

Found better pictures of my filler hose installed and the junkyard gas filler I found. Note the size difference.
