[packman]

Said NAPA radiator hose number is 8104 and under the barcode is R727775.

Under what application did you purchase the pump?

[mrltd]

Fox Mustang (86-93)

excellent thanks.

Also, I think I read in another thread that you can wedge 1/4" fuel line hoses down in on both sides of the new smaller-diameter Mustang pump when inserting it instead of using an extra hose clamp to keep the 255lph pump solidly in place.

Posting this b/c I gave a link to this thread to the shop who are installing the same unit in my '82 Mark VI with the Mustang motor.

Thanks man, but I easily found that since search finally started working right on the site since the VB update. Figured jamming fuel hoses in the edges was better than a no-tip condom of non-fuel-rated radiator hose even if it is the proper diameter in and out.

Apparently they had to pry the exhaust aside to get the fuel tank to drop out of it and it might be done tomorrow if I'm lucky.

mustang pumps are direct bolt in on 90-91 cars btw guys

So if a dude didn't want to do all this modification using Chrysler hoses and stuff he could buy a 90-91 LTD/GM gas tank & then mount a Rustang pump in it?

I suspect that would work but don't let the mods for the mustang pump installation scare you. It's not a big deal. Just find a radiator hose (I had a couple old ones stashed in my junk pile) that fits the OD of the mustang pump and you've got the most difficult part handled. I bought a foot of bulk 5/16 fuel line and trimmed it to length, to properly reach from the pump to the pickup. I also extended the wires maybe 2". Add the second hose clamp to secure it in the rubber boot.

Follow the pics and tips in this thread and you'll be golden.

I wonder about a piece of rubber being bathed in gas for a few years...Anyone have any long term experience?

Any rubber does ok until left out in the atmosphere for to long and drys out then it will most likely rot. Some rubber is a bit more resistant to it than others. NAPA IS ONE THAT SELLS larger dia fuel filler inlet hose. They also handle hose that is more resistant than their std fuel line

I bought a fuel pump that looks like that one from RockAuto; it came with a sleeve to make it fit inside the hanger assembly, and hose pieces, wires, clamps and such to make it fit everything else.

Feels like it lost some power compared to the old one, but it runs better and doesn't sound like it's going to explode. Could be something else causing it, I'll find out after I change the oil and battery cables.

(Yes, I'm still working on that. Thing's been grounded for a month for various reasons.)

Rubber hose not rated for fuel/oils will break down fairly quick when submerged in gasoline. When buying fuel hose now, look for the kind with a green stripe/lettering...it's designed to handle ethanol blended fuels. "Any rubber will do" is incorrect, contrary to our "engineer for Ford" friend.

There are actually special types of fuel line intended for in-tank use. Typical fuel hose is lined on the inside, and has a standard corded rubber outer bit. The lining is to protect it against fuel and ethanol, the outer bit is simply for abrasion resistance and pressure handling. Submerged lines should be completely lined so they don't disintegrate from soaking in the fuel full time.

SAE30R9 is typical hose, SAE30R10 is the submerged stuff.

Hoses not intended for fuel use don't have that lining, and they turn to slimy goo after a bit of time soaking in gasoline or other oil. Ever grab a radiator hose on a car that spews oil and notice its spongy feeling? Thats the rubber breaking down from oil exposure.
