Topic: On a scale of "it'll be fine"-"Part-out level fuckup", how concerned is everyone that I used PVC pipe as a spacer/cradle for my fuel pump?

If it was easy to replace I wouldn't be worried, but in the fuel tank is a bitch to replace. You have to remember the pump will still generate some heat also which can affect the compatibility of materials.

PVC, from what I've been able to gather, is relatively strong against gasoline even under some "unstable" environments.
I was able to find a chart on a website that was referenced from several different small engines, and truck forums:
Chemical Resistance Chart - Jensen Inert Products

I'm positive gas canisters themselves are made of high density pvc of some sort, so you should be fine.

How did you clearance the canister for longer fuel pump? Did you completely notch out the top portion?

Yeah, I cut out the top of the canister around where the pump sticks out just enough for the top to clip back on. Then just hoseclamped the factory fuel feed line onto the new pump. Since I have a full return system, the return line just feeds back into the canister.

I reused the factory fuel sock because I dont think you can buy it seperate, but It would be nice to be able to replace that piece. Kolt?

Not PVC, HDPE. Very different plastics.

PVC chain:


Hydrocarbon (i.e. gasoline):


Looks like the PVC polymer can enhance your fuel atomigauge ratio, aligning the molecules for maximum attribution gain, resulting in improved chain origin when entering the combustion chamber.

Makes sense. This is pretty much the way I had to do it with the Hydramat. Possibly could have bored a hole the same diameter as the AEM pump body to allow the pump bottom to protrude through with the stock housing still holding some fuel. I'm guessing the stock housing is designed that way more for keeping the pump primed than cooling. The gas flowing through the pump should carry sufficient heat away I am hoping.

On lsj, lnf, le5, and l61/lap non California nu6 no. On l61/lap California nu6 emissions yes. You can get the fuel strainer assembly (#32) which is separate from the pump (#34) , which is also separate from the in-tank filter (#37) , and also has a separate housing (#36) that they all fit in. Which is all separate from the top cap with the lines (#30)

I thought it was a different blend of PVC. Good to know.

Ah chemistry. Another life in a past that is now long forgotten.
