Figured since I got the new pump I would throw it in there...

And wow... doing it the right way sucks. :-x

The damn filler neck was always caught on something or other.

Took me an hour to drop the tank on the ground by myself... not bad, but damn...

Beer break, pump install and then back up in there...

Looking good!
I remember the first time I dropped the tank on my GN I just cut all the hoses, to find out those hoses were 5.00 a foot.
So much easier on a 56 Buick to drop a tank.

Good, you had me nervous when I read the first part!

Yea, one word of advice, the straps that hold the tank up... when you take em off, be gentle and do not bend them at all. What a pain in the ass they were... ah well.

Car runs. No leaks. Success.

Give it some time. I wanna make sure this is correctly setup before I go spraying it.

Does any one else who run a walbro notice it being significantly louder than stock pump?

LTb1ow
08-28-2009, 09:25 AM
Nope, just as low as it sits when it hangs. Hard part was getting the body up high enough.

LOL. Some pumps are like that. I put a Holley Blue on my bro's Chevelle and it sounds like a large swarm of REALLY pissed off bees.

Alright, cause mine growls when you prime it with the key before ignition. So far so good... gonna take some time to get back to trusting the float though... LOL

08-28-2009, 10:58 AM
yeah its known that they are way off. full tank mark is like 3/4 tank. i'm going to try and fill my tank up, then put the needle at the full mark. see how that goes

08-28-2009, 11:05 AM
LOL.... wouldn't advise it if you plan on installing a fuel pump anytime soon....

My Walbro also hums when I turn the key on, significantly louder than stock. My dad has some kind of Holley in his 65 corvette and that thing is LOUD

Blacdout96
08-29-2009, 09:23 AM

I belive you need bigger balls to cut the hole.
You took the harder yet potentially life saving way.

the 255 is def louder than the stock one but its not bad at all.

Correct me if I am wrong, but doesnt he already have a 4th gen tank :scratch: :nod: :rofl:
I picked up a plastic tank for $50 with about half a tank of gas in it and I bought from someone here a sender for a plastic tank. He had the tank too but that wouldnt fit in my beater..... :shock:

LTb1ow
09-01-2009, 08:48 AM
Mine is metal though, are the plastic tanks stock with removable filler necks?

It technically isnt a removable neck but it is rubber coupled to the tank near the bottom making for easier ingress and egress. I put one in my 91 GTA :nod: it was a LOT easier putting that one in than taking the old one out

Whoops, I dropped the word plastic, that was kind of important to the conversation I suppose. :lol:

Yes you did.

So I would need to find a 98 one right? 98 is the only LS1 with return line I think yes?

PolarBear
09-01-2009, 01:28 PM
From what I understand the 98 tank is steel still. The others all have a return, you would have to remove the internal pressure regulator though and re-plumb part of the system. The plastic tanks have a "T" block right before the fuel filter that the filter screws into. You could easily replace the "T" with some fittings to make the plastic tank work. I am not familiar with the LT1 cars but if the fuel filter is in the same place as the 3rd gens had then you could make it work fairly easy with 2 adapter fittings, IIRC from memory. I ran -6AN line from the tank all the way to the fuel rails but if I had to do it again with stock factory hard lines I could figure out which fittings to buy.
