1987 GMC V1500 Sierra Classic LS swap/build

LMC Truck has the gas filler hoses you need. They list a LH and a RH but don't distinguish between the 16 and 20 gallon tank. I believe the 16 gallon use the same hoses as the 20 gallon.

Looking good. I applaud your work on this truck.

Thank you for the compliment. It is very appreciated. It still has a ways to go, she may look a little ugly for a little while but hopefully she will drive excellent!

I checked LMC and only saw the ones for 16 gallon. I have my original hose/setup from my 87 16 gal tanks, it won't work. They have a metal elbow that extends the hose back about 8" or so to reach the fuel door.

I also have a used filler neck that came with a early 80s model 20 gal tank I used to prototype with. It has just a rubber hose that comes off the tank about 2" then 90deg up to the fuel door. The one I have is hard as a rock and dry rotted so I need a replacement. I also need the other smaller breather/vent hose.

I should have taken pictures.

If you look at my build thread...I understand ugly and I embrace it. I would rather it be functional that pretty. No don't get me wrong I will one day get mine painted and I would love to have a good looking function truck but the cosmetics come last.

Sorry to give you inaccurate info. I too was trying to go off of memory on how my original PS tank was set up and looking at what pics I have (only drivers side of current set up) don't tell enough story. I had a bed set up for dual tanks with both filler hoses but did not have the PS tank or switch. I scrapped the original bed because it was too far gone with rust and I stayed with just the DS tank. Maybe someone can post a picture of the PS 20 gallon set they have to guide you on how to proceed.

I too will one day to body work/paint and all that but it will be when the rest is done. In the past I have painted projects before they were finished and then when I worked on them I damaged the paint. Never again!

No problem! Yeah hopefully someone else will chime in, only other route I know is to take the hose I have and try and match it to a radiator hose a part store and cut what I need.

Does this look like the hose you need?

For the VSS I'm pretty sure you can just splice the the '91 wires in to the newer harness... You'll also need a momentary switch that'll let the PCM know you're in 4LO. I've seen some guys just wire a toggle switch in the dash but the cleaner way to do it is add the switch to the T-Case shifter like this guy did:

I have no idea how to get the BCM to recognize the doors though...

NorCal it does look like the one I need but holy moly, that is expensive for like 10" of hose with a 90 on it. I also need the filler vent hose.


I really like the idea for the switch on the shifter!

Yeah I was really surprised when I saw the price too but there aren't a whole lot of options out there for them either... I googled K20 filler hose and came up with part# 14000286 that looks just like the one in that other link so you might try to hunt one down that way.

Have you checked LMC yet? It looks like they have everything you need (filler and vent hose) but it's not a whole lot cheaper...
