    31 gallon tank conversion pictures

    I took out my dual tanks and put this 75 Suburban tank in between the frame channels just behind the cab. A guy at the wrecking yard said I could put a 72 tank behind the seat but I can use that space for storage. The sending unit that was in the tank works fine with my gauge.

    79 c3500 sm465 to nv4500

    I’ve got a NV4500 I’ve been thinking about putting in my 79 2500 and I’ve been reading up on options. I’m still undecided because I like my MS465. I’m thinking about getting a Gear Vendor overdrive instead. They bolt directly to the NP 205 T case, and I’d need to shorten the driveshaft but...

    Can’t decide on single or dual tanks

    Ill see if I can get pictures posted from this phone but may need to wait until I get to my computer in town. Look at your cross members, I bolted 3/16 plate to the bottom of the hat, so to speak. The crossmembers are made of hat channel. My three plates each bolt to both sides ( both...

    The EP381 is an in-tank pump? For the 90s Suburban?

    Can’t decide on single or dual tanks

    I saw somewhere the rear center recommended but I hung my spare tire there with the little winch, so put it between the two crossmembers behind the cab. I’ll put up pictures in a few weeks. It’s kind of close but I glued some plastic and rubber here and there, ran the straps over the top...

    Can’t decide on single or dual tanks

    One of my dual tanks in my 79 K20 developed a rust leak while I had it out cleaning it up, replacing the sender. So I thought this would be a good time to swap both tanks for a single and I got a 31 gallon tank from a 75 Suburban. Both type senders should work with the gauge as both are 95...

    Truck left me stranded today.

    Isn’t it possible to find an electric pump that can pull sufficient fuel high enough and far enough to service both tanks in a safe convenient location reliably regardless?

    Does my 79 have a fuel filter in unit?

    Ok, good to know, thanks. I’ve also got a 92 K20 Cheyene thanks very much. I did think about putting the filter in the return, or did you mean that to be a secondary filter? Becuz it seems like a good idea to have one after the pump. I’m not afraid of the plumbing but I like reliability and...

    Does my 79 have a fuel filter in unit?

    Like I said in my previous post, I’d only be capping off the port or ports that were not there from the factory. The added ports are just carrying fuel, not vapor, back to the tanks. If you read the above posts you’ll know the reason for doing it.

    Does my 79 have a fuel filter in unit?

    Thanks, the one I took out didn’t have rubber on it, Ill try to find one without rubber. But some online sources don’t provide much description.

    Does my 79 have a fuel filter in unit?

    Picture the stock fuel filter, Rusty Nail, if you can. it’s got two ports. One pipe port bringing fuel to it, and one square block threaded port to take the pipe going to the carb. That’s how mine has been from the factory 43 years ago. (I rarely send pictures because I only know how to do...

    Does my 79 have a fuel filter in unit?

    Thanks, that’s how I’m planning on doing it, all right, except there are two vapor lines already in place from two tanks up to the engine bay. Also I’m considering going to a single tank between the main rails, and am looking for info on how to do that or if there were any such things from the...

    Does my 79 have a fuel filter in unit?

    Wow, sounds like what I do when I can’t wait to try out a thing I’ve been working on. Once I forgot to replace a temporary oil pressure gauge plastic pipe, with copper pipe. Had 200 miles on my own long block rebuild and pulled off the highway so the machine shop could listen to my new engine...

    Does my 79 have a fuel filter in unit?

    THANKS, I appreciate the offer. I didn’t know that much fuel is returning from the fuel pump. Thought it was 99% fumes. If I cap off the return ports on the sending units, I also have to cap the pump port? How much pressure does that return have at the pump, the same as it has to the...

    Does my 79 have a fuel filter in unit?

    Thanks, ordered. I was going to return it to one tank, would it matter which tank? I’m guessing it’s got to do with vacuum.

    Does my 79 have a fuel filter in unit?

    O’Reillys says they have two port sending units and three port. Does the third port go to the fuel pump? My old pump just had two, but I want to replace it with a three port to get the vapor lock protection. Thanks

    Does my 79 have a fuel filter in unit?

    Thanks, I’ll check that carb filter too. The sock looks bad, I’m ordering two Spectra units, need to decide if I want the passenger side one to have three ports. I’m going to a three port fuel pump so I can avoid vapor lock, but don’t know where the line goes to from the fuel pump, the extra...

    Does my 79 have a fuel filter in unit?

    Thanks, I just took the tank off, no rust in it. Where is there rubber in the tank? Never bothered blowing air through a line, I’m replacing all the hoses and both sending units. I sure appreciate all the great info guys

    Does my 79 have a fuel filter in unit?

    Thanks, I looked again but there isn’t one anywhere. I’ll try a little compressed air from a line into sending unit but just remembered my gas gauge does not work so will drop the one tank anyway

    Does my 79 have a fuel filter in unit?

    I replaced the fuel pump in my 79 K20 350 and it’s not pumping gas so I tried pumping frim both tanks separately with an electric pump but still got no gas, both tanks have gas, one is almost full. The service manual says to clean the filter on the sending / pickup unit if it’s out, but before I...

    Manual choke for a 350 quadrajet

    The electric choke on my quadrajet didn’t work when I bought it, the butterfly valve is too loose. I’ve put manual choke cables on other carbs before but I’m not so sure it would work on this one, as I tried choking it by putting a small vise grips on the lip of the barrel, stopping up the...
