Are you saying the rubber fitting is missing from the end of the plastic vacuum line?

Welcome Terry! Glad you've found the site useful.

FULLY torqued! (the Dr bugs out every time they check my BP!)

I think Walker crinkles the already aluminized tube. Certainly the compression in those bends changes the structure, because they are not normalized (annealed) after bending. There's always going to be some pressure for EGR (unless your truck has zoomed, like a top fuel dragster.... 8th bends are pretty common. Even 16th bends aren't too hard to find. I've never seen 18th bends off the shelf. You usually have to pie slice those from a U-bend or something..

I think the only "sir" here may be Gary! 😄 There sure are a lot of variations and nuances. That's what's so great about having all the documentation (and even with that, we find anomalies and omissions everyday!)

Welcome! Very well done with that tailgate letter! Though they look good on your truck, mine came with those argent 'turbine' wheel covers. Unfortunately they love to load with ice and mud throwing my wheel balance off so much that I would pull over to check if the nuts were tight. (Turns out it was the nut behind the wheel! )

I'll do what I can. Still trying to scrape together rear end parts. Feeding myself is becoming ridiculous.

Looks great! Those crinkle bends don't last 2 years up here in the salt belt, but shouldn't be a problem in Dallas.

Is his name Sammy Davis? Bands and Wiggins couplings were popularized for hot swapping turbos. I wish they were readily available back in the day.

I certainly didn't mean to be critical, either. Matt brings decades of experience to this forum. Very few forums have anything but "cool kids" fishing for page views and likes

You could set up something like patreon. Sure there's an overhead cost, but they take care of all the currency conversions, monthly subscriptions, annual,one time, it doesn't matter.....

There were three different versions of Hot Fuel Handling, that I know of. It all depends on which switch you have, and how the relays and valve were wired.

My 460 has a mechanical pump WITH RETURN. The sending unit is 3/8 feed and 5/16 return....

This was the distinction I was trying to make, but Mat said I was wrong. 🤷‍♂️

400 went out in '83, so it has the small bung, and won't fit. If you have a single line (no return) use the 300/4.9 sender.

Thanks Matt. The welder I found says he has done this typerepair on several Chevys and he gave me references. I'll check em out. By minimizing the size of the patch you minimize the panel distortion. I don't think anyone makes front wheel arches, just complete fenders A good body man can fit some metal and make it almost good as new. Then use a waterproof filler (I use West System epoxy) so it won't hold water, like Bondo does That guy Jerry shows it done (on a Chevy pickup)

Yeah, I get it Next you're gonna tell me it's in room 1099 bld W2

Does the 4.9 have a return, or do they get a 3 port valve and just a pickup, deadheaded again the float valve? I thought by '86 (big bung) the 4.9 had an in-tank pump..

Tax day. How fun!

Sure you can buy a sender. The issue with '86 is that it has a big bung, so you have to get one for a 351HO/460 that had the mechanical fuel pump. JBG seems to have them for a decent price.

I pop riveted a small bar across the seat so I had somewhere to attach...

If something starts to coalesce I'll be sure to pin it to the main page. 👍

Nothing yet. A newer member from Pennsylvania inquired about having a more local meeting than Skiatook Oklahoma..... I guess he lives in the capital region somewhere. 🤷‍♂️

Would you come to a forum gathering in the Harrisburg/Carlisle area?

Interesting! I suppose any plastic saturated in fuel and vapors will eventually either get hard, or soft as gum, like the blue nylon fuel lines do. The fact that a puny little steel line can last 40 years is testament to its durability.
