LS Swap fuel pump ideas

My wagon has a 454/ 700r4 in it. Pulled it out due to oil leaks and little bit of oil burning. Trying to decide whether to stay with it or swap in a 5.3/ 6.0.

Anyone have any thoughts on how to address the fuel pump? I see Holley has a new inline pump that is supposed to be quiet, but I have my doubts. Also saw they have a retrofit fuel pump housing deal that might work.

I've done a bit of searching, not really found much info.

Re: LS Swap fuel pump ideas

I used a walboro in line right by the tank with a corvette regulator/filter on my 6.0. Works good

Tighten it till it strips and back it off a quarter turn.

Re: LS Swap fuel pump ideas

I'm running a Tanks, Inc. internal fuel tank with the Corvette regulator / fuel filter. The regulator return is on a short length of return hose to the fuel tank because I have a "returnless" fuel rail at the intake manifold.

Is it noisy at all? In my 71 is a tanks inc tank with a walbro in tank pump and its ok. Tried a Holley Blue at one point and it was terribly noisy.

Do they make one for the wagons? That would be awesome.

Hello George,

I don't know if they have a tank for your wagon but I predict they do. Here's their web site.

Honestly no, sounds like a in tank pump. I have heard the holleys and they are very noisy.

Re: LS Swap fuel pump ideas

I put a fuel pump in my stock 72 wagon tank. Wasn't hard to do, no modification to the tank except for a vent line. The car has 17k miles on it without any fuel issues...except for the one time I ran out of gas It will pick up fuel with no starvation with as little as 1/2 gallon in the tank. When I ran out the tank was empty.

Re: LS Swap fuel pump ideas

I put one in my tank when I did my LS swap...wasn't that difficult to do.

I think it's a far better better idea than an inline pump.

Re: LS Swap fuel pump ideas

I run twin Aeromotive A1000 pumps on my car. They can be mounted in tank or external. Mine are external and surprisingly quiet. I'd also suggest running their pump controller to vary the speed of the pump.

Lol, it's hard to take the sound advice of a guy running a 10:1 429 with half an exhaust!!

I'm running the Tanks Inc tank with the in tank 255 Walbro. My exhaust is loud but you can still hear the pump. It's not overly loud but noticeable if paying attention.

around the 27 second mark:

While seeing if anyone has had this same issue I ran across this video, it's pretty well put together and the end result is great.


Looking up DeatschWerks they do have inline pumps, but I do not have any longevity info on them. I asked the guy that posted the above video how the pump is doing, hoping he replies.

My buddy is running Bosch inline pumps in his pickup but keeps burning them up, thinking he's victim to knock off pumps?

I looked on their site and no tank for the 72 yet.

Re: LS Swap fuel pump ideas

I run an in-line pump and a Corvette bypass filter. I can here the pump when I turn the key on but cannot hear it at all with the engine running. Its pretty darn quiet.
I had the same thing on my 67 convertible with an LS1 and had over 100k mikes without an issue.

I would like to do this, not sure how to do it. I installed the tanks inc tank, but it was just put it together.

An in tank pump would be my preference. Not sure how to go about it.
