Fuel Filler Housing Design
Hi All,
We're working on a '65 c10 father-daughter project and thought I'd include a drawing of the fuel filler housing we designed (see attached PDF below). Please ignore the welds as our intent was only to tack the seams. We also installed it higher than the bed floor because we are going to install wood over top what is left of the original bed floor -I feel like if we take the bed apart, it will cost more than I want to invest to put it back together. Because of this, we installed the Blazer-style fuel tank without removing the box. Here's a video link in case your interested in doing the same thing: https://www.youtube.com/watch?v=MQ_JNM3lkpA The parts we used: Blazer style fuel tank: Classic Performance Products Fuel Tank Conversion Kit 21 Gallon OEM-Style Chevrolet C10 1967-1972 Classic Performance Products: 6772FMT-K Filler with Keyless Cap: ISURE MARINE 1-1/2"(38mm) Boat Fuel Deck Fill/Filler with Keyless Cap with Screws, Marine Mirror Polished 316 Stainless Steel Hardware Angled Neck for Boat Yacht Caravan Air breather elbow (I drilled and tapped a hole in the filler): Podavelle 1/4 NPT Male to 3/8 Hose Barb Fitting Adapter 90 Degree Aluminum Black Fuel filler neck: Gates 24702 Flexible Gasoline Fuel Filler Neck Hose-3' Length, Inner Diameter 1 3/8" Tank vent valve: Holley 19-174 Remote Mount Vent Valve

Re: Fuel Filler Housing Design
This is a picture I took from this forum I used to make my filler. It works okay but it's a slow fill. About 1/3 speed. fine for an occasional driver but it would get annoying for a daily driver filled often.

Re: Fuel Filler Housing Design
Did you include an air return at the fill location? I thought mine might be slow to fill, so I added the air return line. I’m hoping it will speed things up.
Cheers

Re: Fuel Filler Housing Design
My filler is through the rear fender, using the original spout and o-ring seal.
I added a vent line from the tank up to the filler, and it fills SUPER fast. To the point that I need to put in a "splash back" shield in there like modern cars have

Re: Fuel Filler Housing Design
The marine fuel filler I used is cast aluminum.
I took the marine fuel filler to a machine shop and had them drill and tap a hole for the 1/4 NPT 90* elbow to thread into. The 1/4 NPT to 3/8 barb elbow was also aluminum, and since its connected to a 3/8" rubber hose running from the gas tank, it acts as the air relief line while fueling. ***Make sure you don't use a brass fitting with an aluminum fuel filler as it will corrode over time since that would be a cation in direct contact with an anion in which the aluminum would slowly disappear.*** I don't have a picture yet, but I have included a 2D drawing outlining this. I'll try adding a picture later. Cheers.
