Blazer and Jimmy Fuel Neck Styles

[davischevy]

I thought I had some NOS straps around here, but didn't lay my hands on them in my short search today.

I think that strap may still be available from GM. I will look in my Chevelle assembly manual and see if I can come up with a number.

BTW, it always bothered me that there is so much extra strap that I had to creatively use up.

[DeadheadNM]

Jeff completely agree with you and thanks for the good words.

The plastic ties seem resilient to me and the nubs that keep them locked in place are shallow. I don’t expect you will damage it upon removal if you are cautious. Also, I can only find 5” and 7” aftermarket ties. I buddied up two ties and placed them around the hoses for now.

Larry thanks. If that Chevelle tie works I’d love to have a lead for a source or even a part number to chase.

These people say they have the straps.11 3/8" long.

Thanks Larry I just ordered a package of 10.

[DeadheadNM]

Arrived. Style differs from oem. These are just typical zip ties.

[Moreyel]

AC/Delco zip ties!
I don't want to ask how much those were!
Please call when you get a chance Pete.

[davischevy]

How is that for bait and switch?

I guess I better start digging through my archives.

Received some Gates fuel hose today (USA made) because I’m a hoarder. I can confirm a good fit. No local parts shop could obtain this Gates hose - Jegs had it but I wonder for how much longer...pricey.

Lol! You are correct. However, this is in my stash of leftover 71-72 aux pickup fuel tank parts. Alas, no build going for me.

Deadhead- Does the Gates 24702 fuel hose you picked up have a slight molded bend or is it straight through?

I'm trying to find the hose with the bend. I see photos of both straight and with the bend fir the same part. Amazon has a photo with bend but several complaints the hose received had no bend.

[DeadheadNM]

It’s straight hose, no bend. A 3’ section.

[DeadheadNM]

FWIW I’m u aware the any OEM fuel neck hoses were molded w a bend. Would like to know if so.

[Green Monster]

My initial search showed the 24702 with a bend so I thought that was the right hose. A previous owner (15+ years ago) installed a newer style poly tank but the hose used to connect the fuel neck to the tank was straight but is bent and has a slight kink in it. The tank isn't period correct but it hasn't caused me any problems, other than the hose kink. Maybe the straight 24702 might be a better option than the kinked hose I have now.

[Thealien]

Out of the 3 I have had all had straight hose that you bent a little?

If you need a 1 3/8 90 degree fuel hose this place has a nice fuel related parts assortment.

Thanks for sharing the bent hose source info, Thealien.

Short of replacing the tank with a fuel neck, I would need an S shaped or flexible fuel hose in 1.375 diameter.

The original posts contain great info with fantastic photos that was shared. Tha KS for sharing.

The evap system seems a little excessive for such a primitive vehicle.

When I was young we used to rip all that stuff out. Now I realize that GM wasn’t that stupid. It’s nice having a car in the garage and not smell like gas!

It’s hard to follow in the diagram. Is the center hose the one that goes to the front?

[1rippen6]

Found this on the blazer I'm parting now

[DeadheadNM]

Buddied up! That’s what I did. Thanks for posting.

[DeadheadNM]

Thought I’d add examples of the gas caps correct for the various K5 years. Feel free to double check. Photos are borrowed from past threads.

69-70 used 3914958 primed if not CST (top) and 3927086 stainless if CST (lower)

3927086 is also correct for 71-72 Ser 20-30 trucks w body side molding or Cheyenne model. 3914958 also correct for Ser 20-30 71-72 trucks without side molding/non Cheyenne.

[DeadheadNM]

The 1979 era parts manual doesn’t call out a cap for a 1971 Blazer specifically. I’ll triple check.

Cap 3975177 is listed for Ser 10.

[DeadheadNM]

For 1972, 6263474 is listed for all (and Ser 10, Ser 20 Suburbans, and 72 auxiliary fuel tanks for fleet sides).
