On the soft line, I just checked back to what I used on my K30 buildup - it was for a 1993 S10 4.3 pickup, ACDELCO 18J821 - it's about 4-1/8" longer than what the original was, and it has the same end fittings. :2cents: |

We're using one for a 1984 K20 5.7 Suburban, 31 gallon, big neck, w/o a tank baffle (14B). Research showed 3 are available in this same size & shape early 14A has a small fill neck and then 14C large fill neck with added in tank baffling/sump for an in tank pump. This sending unit has a return line port if we decide to try a newer throttle body type FI later on, to be plugged for now.

Jim, your 2 cents is always worth at least a $1.25! :lol: Good to know as this one I'm trying to use is pretty short. Anything I should know about the front soft lines? Also can you tell me where did you get your prop valve and is it a PV-2? Thank you sir! |

I had no problems using the regular K20/K30 stuff up front on Red, if I dug around enough I could find the PN's but they were just the year matched parts for my '87 donor. On the K30 I got the prop valve from Inline Tube, their PN PR102 - it's functionally the same as PV-2, but it has the correct style electrical connection on it to use the original warning light plug. I did end up having to extend that harness, though, because I mounted it down on the front cross-member (as the donor did). In fact, I went back and checked the photo: http://i138.photobucket.com/albums/q...ps3af6511b.jpg And sure enough, it's stamped PV-2 on the bottom :lol: You can see the original style rubber boot connector in there, as well. Hope that helps! |

Jim you’ve been and continue to be a great help, I do appreciate it thank you. I took your advice and ordered the longer S10 soft line and so I’m thinking your 2 cents are now at least up to 2 fitty! :metal: With our plan of dropping the axle down to bleed the system the extra length is going to help.
Ha, that is you photo bombing the pic right? I'd noticed the change in the boot connectors from earlier to later 78 & up. Thinking the only difference is they switched to a plastic screw in switch/insert we kept the old setup (sure it’s passed a lot of muddy fluid over the years) for mockup and still have a newer style pigtail. It’s kind of a tossup on which style to run no getting around a splice as we will position ours in the same area you did. Rest of the brake system is 84 K35 so I’m leaning that way with the later style prop valve. |

Functionally, the switches are exactly the same, so it really doesn't matter. The '78+ ones are easier to disconnect, if you ever needed to do that, but otherwise, it's a wash. I'm using the later style one on my '50 ;) |

While the new front housing is out (hot tank, king pin cones, etc.) stuck the old one back in place to set the upper shock mounts we also got the front brake line mounts in as well. During our earlier mockup of the hard lines I had thought we were going to have a run an additional splice in piece for the rear brake line (to short?). But after straightening out a few spots in the front section it looks like it will just reach.

Started working the front fuel hard line it’s approximately a -9-10’ straight shot. The rear most section looks like it will be this Gates 6LOC hose as it snakes around and gets fairly tight in back by the tank. Our plans also include adding this old school large screw on remote fuel/oil filter setup I pulled off our RV donor. I was able to cross the old Clark filter to a NAPA, Wix, Fram which are all still available. Pretty sure the old tanks on the RV were rusty is why somebody had put this on it. Its bit overkill I know but our truck could practically run on mud if needed with that filter! :lol:

Re: 72 K30 Build
I like the canister fuel filter idea. It really adds to the workhorse truck vibe. Thank you for the great build thread.

Re: 72 K30 Build
Keep up the good work - this is gonna be super nice & so worth it when you finish!

Re: 72 K30 Build
Im going to have to keep an eye out for a filter set up like that for my old Ton when I get to it ,mine has fuel issues too .

Re: 72 K30 Build
I tape cow magnets to regular plastic filters and it stopped the issues I had with a rusty tank

Re: 72 K30 Build
You are totally on a roll Brett - looking great!

I’ve been expecting our new replacement front housing to be done anytime now, just needed a hot tank, new king pin cones installed and inner seals. We’re onto our 2nd vendor after the 1st was just too busy, we kept getting the old we’ll get to it next week response. Ring gear is on the carrier and we’re pretty much ready to reassemble when it gets back. Thinking now will be a good time to finish putting the rear brakes/hubs together. Anyone notice an issue with the old shoes?

Ha, I'd finally noticed those shoes were different just the other day when I was about to start pulling the hardware off of them they don’t call me Mr. Observant for nothin’. :lol:
The newer longer rear soft line is here (thanks again Jim). The keyed fitting has seen a change but the newer style is all the local house of hose had as well so a quick modification to the bracket was an easy fix. Managed to modify it so it even still locks in place and won’t rotate. Shoes are on and ready for the drums/hubs to be added. New CPP proportioning valve (PV-2) arrived and is mounted all that’s left up front is the soft lines and the lines to the MC. |

That chassis is looking stellar! |
Re: 72 K30 Build
Thanks Jim it's just nice to work on something clean! :lol: Yeah I'm guessing somewhere between 1984 to 1987 they made this change.

The drums/hubs are on good enough to roll (no axles or fluid yet), they’ll have to come back off for emergency brake cables in the near future. Buttoned up the fuel line, massive fuel filter shocks etc. Time to move our attention to the front diff.

Looking good ,staying tuned .
