Epoxy in gasoline???

[lynden]

Hey guys,
I replaced my fuel pump a bit ago w/ a cheap one I found on the interweb. It works well but the output tube is just a smooth piece of plastic (no barbs or ridges). I have some good, pliable tubing going up to the housing. My problem is that the hose I'm using continually slips off. I have a screw type hose clamp but it still will only last about 4 weeks before it slips off again. If I used epoxy will it degrade in gas? If so, I'll just try to get a different fuel pump...

Thanks in advance!

why not get a fuel pump made for your vehicle.....let's not ghetto rig our vehicles....especially in the fuel delivery system as that system is fairly important!

The reason it slips off is because the diameter of the after market pump is 5/16 and the factory one was 3/8

change the hose to a smaller diameter slide the hose all the way on and use the correct high pressure fuel injector clamp and it will not slip off.

Lynden,

To answer your question. Typically yes, epoxy resin have an excellent gasoline resistance. Check the chemical resistance with the epoxy manufacturer.

That said... You should get an OE pump. You don't want to cut corners in that field. You could end up hurting your self, if there is a gas leak.

sorry guys but swapping out the pump is not cutting corners its just a different method of repairing a failing pump.

There are tons of trucks running replaced pumps without any issues.

The other advantage is that once the swap is done you can carry a tiny little back up pump and swap it out on the trail in 10 min.

If you only want to run OEM then maybe you should just go buy a LR4 and get a warranty.:rofl:

I used the pump that was rec on this forum "96 Impala SS" but you do have to change the hose as I believe it was a different dia.

If you're dead set on using the epoxy, just go to a hobby store and get some clear fuel proof paint made for RC aircraft. Paint this over your repair to seal it and it will definitely be fuel proof.

Yes it is. If the pump motor is worn out, there is a good chance that the steel plumbing is nearing the end of its service life. There is an equally high likelihood that the plastic on the top of the assembly is nearing the end of its service life and is just waiting for the opportunity to leak.

I've posted multiple pictures of fuel pump assemblies with rusty plumbing that leaked and pictures of the top of the assembly where there were obvious failures of the integrity of the plastic.

Everyone has a right to their opinion but I don't see this as being a wise CB swap. As these trucks continue to age, the parts will only become more fragile and weathered.

The price difference between the pump motor and the entire assembly on non-AEL trucks just isn't great enough for it to be justified to me.

I second PT. Just get yourself a genuine pump and forget the rest !!!
