Add One-way valve to keep fuel at the carb? '86 Burb 454
Sounds like a great easy check. I was planning on dropping the tank down a bit and checking all the line connections at the sender, I'll just pull them and blow a bunch of air through when I do it. As badly deteriorated as the old hoses were, I would not be surprised at all if there's a chunk or...- suburble

What have you done to your square lately??
What have I done to the 'Burb this weekend? Turned it around in the driveway Saturday morning to change out the T-stat to a lower temp one I bought and put on a phenolic spacer... Then I couldn't find the parts in my disaster of a garage... Enlisted the kids to "help". About 14 hours in so far... -
Add One-way valve to keep fuel at the carb? '86 Burb 454
Yup. My thinking was I should be able to tell pretty quick if it's a drain-back issue if I put in a check valve. I've got a cheap 0-15psi pressure regulator valve, too- If it does look to be a drain-back issue (due to bad pressure relief at the pump) I'm thinking of throwing that on the RETURN...- suburble

Add One-way valve to keep fuel at the carb? '86 Burb 454
Does anyone have an exploded view or disassembled pics of one of the mechanical fuel pumps from a square? I'd really like to see how the pressure relief / return line setup is done. Thanks, -Josh- suburble

Add One-way valve to keep fuel at the carb? '86 Burb 454
Good advice on checking the RUN voltage, simple check and I will do it tomorrow morning. I'll give up on it being a fuel issue when I can see good fuel flow in the filter when the problem happens. For now, when it first starts acting up, the filter is almost empty /completely empty. Rev it...- suburble

Add One-way valve to keep fuel at the carb? '86 Burb 454
Still have the factory Evap system, but everything is in good working order, all new (fuel rated) soft lines throughout the system including the vent hoses at the Evap cannister and tank. I pulled the pushrod and replaced with new last fuel pump change, removed and inspected it (and the cam...- suburble

Add One-way valve to keep fuel at the carb? '86 Burb 454
Mechanical fuel pump is actually the 2nd replacement in less than 2,000 miles. Previous pump I took off because of this same issue, thinking it must have a bad diaphram or relief spring. Pushrod is new, and I did look through the access hole as best I could and didn't see any signs of abnormal...- suburble

Add One-way valve to keep fuel at the carb? '86 Burb 454
Guys and Gals- I'd appreciate some input, especially if anyone has tried this... I'm having what I think are heat soak issues causing me to stall out after extended driving at low speed / stop-and-go, and start-up and idle issues after being parked hot. I just changed out the...- suburble

What have you done to your square lately??
Now you're making me nervous :) It looks to be a 3-part assembly with the filter / end cap sonic welded on, so effectively a 1-piece as far as the user. Good point on the heat concerns, but I've been running it in Phoenix for about the past year and haven't seen any signs of melting yet. I'll... -
What have you done to your square lately??
I've actually been pretty impressed with this filter. It's a one-piece deal, pretty thick plastic, and it's really useful for a quick visual to make sure fuel is flowing. Made it real easy to diagnose the mechanical pump as the culprit when I had problems. I found it in the "help" section at... -
What have you done to your square lately??
Spent another 2 hours under the 'Burb this morning getting the new mechanical fuel pump on and replacing soft lines. Passed emissions and got my tags renewed, Woo-Hoo! -Josh -
What have you done to your square lately??
Spent about 1/2 hour under the 'Burb in the driveway trying to get the two $%&^$#%&* bolts out that hold the fuel pump to the block. Man,I clearly wasn't planning on replacing it! Got 'em broke loose at least, then had to take the kids out for the "you did a good job in school this year" dinner... -
Running a carb with in-tank electric pump on 'Burb?
Hey all- I've been having recurring fuel delivery issues on my '86 Burb. I'm also planning on eventually (down the road) converting to a Fuel Injection setup of some type. For the interim, I'm in need of replacing the mechanical fuel pump, and I'm considering the following...- suburble

Are you guys in Phoenix? I might be down for a show or two now that I've got the 'burb (mostly) sorted out. -Josh -
What have you done to your square lately??
Woo-hoo! Sorted out the wiring on the dual battery setup and got it up and running. Did it right, with soldered lineman splice connections and heat shrink too. I hate going the cheap crimp butt-splice route if I've got the tools and time to do it right. Found the problem pretty quick-... -
Harbor Freight Tool/Product Review
Hydraulic Wire Crimper PN 66150 I was working on an Alternator upgrade and wanted to crimp some 6awg battery cable. I wasn't planning on getting a "fancy" crimper, but the ratchet crimper I ordered from Amazon didn't ship and I hit HF. With a 20% off coupon it came to about $44. Everything... -
What have you done to your square lately??
Yeah, I considered letting them sell me a battery, but I had a brand new one already (although discharged from sitting) already, and by the time they got anybody out there we'd have already missed our window for leaving on the camping trip with the group regardless, plus I'd still need to fix... -
What have you done to your square lately??
Tried to get the 86 'Burb in shape for a Scout camping trip last weekend, but we didn't get off to a good start. The alternator and battery crapped out just as we were going to the meet-up on Friday night to leave. Had to take the '05 Sunfire up Saturday morning. All told, things could have been... -
What have you done to your square lately??
I've been playing with the tune on the Edelbrock the past few days, too, and it's really starting to wake up. 1411 electric choke 750, and WAY to lean for the 'Burb with the 454 in Edelbrock "Stock" tune. Strongest metering rod pull-off springs and next size up rods so far and it's still pretty... -
What have you done to your square lately??
New shoes on the 'Burb today, got a deal on a set of Cooper Discoverer RTX tires, HUGE improvement over the Pathfinder ATR tires that came off. The old set was date coded 2002, and was rock hard and cracked. I noticed a new softball-sized lump and bad sidewall cracking after driving to work... -

What have you done to your square lately??
Back on the road and through emissions yesterday after a year and a half as a driveway ornament. I have replaced the entire fuel system at this point. Need to tune it for driveability some more- seems OK but pretty sluggish compared to how I remember. Made it through emissions with good numbers... -
'86 Burb fuel issues
I'll be darned. I'd been assuming it was the 31-gallon tank because they told me at Autozone it should have a 17, 22 or 31 (if I remember), according to the computer, and I knew it took a lot more than 22 gallons. Just looked at the glovebox sticker and it does actually have the 40 gallon. Does...- suburble

'86 Burb fuel issues
Hi all- Been a long time, but I'm getting a start tomorrow on my '86 Burb. I'll be starting a refresh of the fuel system from the tank on up to the pump. I put a new carb and pump on about a year ago and still failed emissions for high NOx readings, IIRC . After some...- suburble
