Update: The newer fuel tank is not compatible, physically too big. I ended up making a new pickup tube and strainer that seems to be working out well. Unfortunately, did not remedy my issue. I ended up bypassing the return t under the hood, and the underhood filter, which seems to have done it. Seems like return setup for the factory carb did not allow for sufficient pressure or flow for the weber carb, and possibly the angle of driving would allow fuel to spill back to the tank rather than further forward to the carb. I would like to setup a return line again, but I think it's going to require a valve that doesn't open till 6 or 7 psi

I'll keep you posted. Waiting on a few things before I get back at it. Going to drop tank and attempt to separate the halves ( after adequately evacuating the tank of fuel and vapors) Haven't been able to upload pics yet, but the inside of my tank is kinda ugly. Have a new tank on the way for an 85-89, and im waiting on a sending unit to match as well, and I'll let you know if the retrofit isn't too bad

Yup, major surgery later this week, I'll keep you all posted. I've got a tank for newer gl's I'm going to see if I can make work, but at the very least I'm gonna need to find a sender for that tank, or get very creative, bc I cannot find a listing for a new one.

The pickup on my gl is not part of the sending unit. The pickup is part of the tank, running a steel tube into the front of the tank, whick then snakes along the inide of the tank to the strainer, whereas the sending unit is its own unit installed from the back of the tank. Sorry I can't show pix off my phone at the moment. So that is a great idea plugging one end and applying pressure, but there's now way to plug the end bc it's part of the tank, and there is no access to the end without pulling the tank apart. At this point, dropping the tank is gonna be a must for inspection and possible repair. If a new tank was available I would just order one, bc as mentioned, mine isn't the prettiest looking from the inside. Tanks for newer models are available, but I'd need to find a different level sending unit,bc 85 and up it looks like they all cone in through the top rather than the rear wall like mine.

Thanks, I'm suspecting something along those lines. I did have the sender out, and was able to get a few cell phone pics. Tank itself looks crusty, tube doesn't look bad where I can see it, but i'm thinking the area of concern is closer to the front of the tank over the hump that goes over the diff, which is of coarse where I cannot see. I may have access to a scope later in the week, but either way it'd be good to drop and try cleaning up the tank. Fuel filter is new, but already has a few flecks of debris, I'm guessing pieces of pickup tube

Thanks,that is the plan, more likely than not I'm going to run the switched feed to the relay through an oil pressure switch

Hi everyone, I'm currently chasing a fuel issue on my 82 1800gl.It is having g a problem going up hills, was thinking that the stock pump was tired or not up to the task of keeping the fuel bowl in the weber carburetor it was converted to. This weekend I upgraded to the Carter style rotors vein pump some of the Weber swap sites reccomend, which is a high flow, but low pressure. It seems to have helped a little bit, but not entirely, or consistently. I have been using a hill near the garage for testing, and for the most part, it makes it almost 50% further up. While messing around with it and trying different things, I have noticed that it will go up the same hill in reverse with no drama. It also runs great on the level, the only exception is if I really wind it up giving it the beans, it'll starve our around the top of 3rd gear. Tank had around 9 gallons in it, and to me the last common denominator is that the fuel is pushed twards the rear of the tank when this is going on. So, sorry for the long winded post, but wanted to be thorough. Curious if anyone else has had a similar issue, and if I'm on the right track. Unfortunately, I think finding out isn't going to be easy, because unless my eyes deceived me, I think the pickup is part of the tank, and the only way to repair it is to dissasemble the tank. From the looks of it, the pickup tube comes in through the front, wraps around the inside of the tank to the end of the pickup near the rear of the tank. I'm thinking that maybe there's a break or pinhole twards the front of the tank where I was not able to see would cause it to suck air when the tube isn't fully submerged. It doesn't look like a new tank for my year is available, so repair may be my only option, unless anyone knows weather or not a newer year may fit. Otherwise, this may get interesting. P.s. didn't mention it before, but the float level in the carb is in adjustment, and I am fairly certain fuel starvation is the issue. With the front up on ramps, and the air cleaner off, you can watch the fuel level in the bowl drop. Less so with the new pump.

Thanks Gloyale! I'll have to search for that fuse holder, nothing in the box was labeled fuel pump or choke in mine. I ended up wiring it in independently to a relay, and was able to do it a) pretty cleanly,and in a completely reversible way. So I may revert to stock wiring at some point. I was able to put a meter on the wires, and it looks like I was getting about 1.5 volts to the pump off the stock harness, so I'm thinking maybe there is something else at play. Good news, I have a working fuel pump. Bad news is it didn't cure my problem. Still starving out going uphills, I'm starting to think I've got an issue with the pick up in the tank.

Hey everyone. I recently picked up my 82 GL which previous owner had swapped a Weber onto, but did not upgrade the pump, as many Weber conversion sites recommend. The pump was working, but not keeping up with the demands of the carb and the bowl would run dry if the car was at an uphill angle. I swapped in a carter p4070 high flow, low pressure pump in, and even rewired the factory plug so it used the factory harness, but the pump will not run. I can hook direct leads up to a battery and the pump runs great, and the car loves it best I can tell, so I'm under the impression I may have burnt a fuse or fusible link out, but I'll be darned if I can find where one for that circuit is, even in my old chiltons manual. I know these have a fuel control module that can be known for being problematic, but it doesn't quite make sense why it'd just go bad like that after just switching out a pump, unless they are known for being that delicate. I think if I can't find a fuse or a fault in the circuit, I may just resort to an independent relay with a fuse to a run position power source
