My truck named Sheila

[elfirebeasto]

Totally late, as its been hectic around here, but today I checked that return line...idk how much is supposed to flow through the return, but it does flow fuel...however, the flow into the bowl still refuses to stop, even if I have the return line open to the air at the first hard line...perhaps the needle seat is bad and allows fuel to get past the needle into the bowl...or maybe there's a clog right in that first hard line right off the carb. So, knowing that fuel flows freely from that hardline all the way back to the tank and that the supply side is over pressurized, does anyone have any ideas?

..."perhaps the needle seat is bad and allows fuel to get past the needle into the bowl"...

 

I would probably start there.....

How do I go about checking/repairing said potential issue? *heads to search bar*

I searched and didn't come up with anything useful, I also checked my chilton manual and it doesn't mention it either. Sorry about this, I feel like checking the seat is a simple process I should know how to do, I've just never worked with carbs before this truck. Also, the needle itself is new, came with the carb rebuild kit I threw in the carb a few months back (hasn't been running much at all since then) but it didn't correct the problem.

do you have the stock fuel pump on the truck??

[elfirebeasto]

Stock replacement available from autozone/rockauto.com and the like. I believe its a Duralast replacement.

What about an adjustable fuel pressure regulator to drop the fuel pressure down some? Set it to 3.6psi as the manual suggests the pressure should be and see what happens. Yea or nay?

Ok, folks, it looks like Sheila is going to be scrapped. Any parts desired? It does have an original Nissan rubber bed mat, if anyone wants that. I thought I'd give you guys the opportunity before that steel recycler. I'd sell the whole truck for $350 cash if anyone is willing to come get it.

FADKL;JKF;LKDAS;KFSDAJ'LKL;JFOVU EOUFOP!!!! so I put a fpr on there, and the fuel overflow problem seems resolved...I do however still have the high idle...it was all the way u p to 4k today. My wife would kind of like me to fix the truck just so we have a truck to haul stuff, rather than an SUV...so I guess I can't part it out just yet. I covered the intake with my hand to try to kill the engine, and it simply wouldn't die...It was putting out a very large quantity of white smoke when it was idling high, and the smoke cut down when the intake was covered...But idk if white smoke means anything in connection to the high idle. What is the possibility that the carb is just shot? Does anyone have a functioning carb they removed and replaced with a webber or something? I'd really like to try a stock carb against my stocker just to see if that helps

SOLD The guy I sold her to did another carb rebuild and replaced the fuel pump assembly, now it runs fine. Ain't that a kick in the nuts. Anyway, thanks to you all for the help you provided! This profile will be deleted soon.
