On the S4 Spiders, and maybe on the 3rd series as well, the fuel line exits the trunk area from the submerged (in-tank) fuel pump, through a rubber grommet visible under the car. The line turns toward the secondary (in-line) pump, and connects to the inlet of that pump via a molded L-shaped hose. Because the fuel line is a smaller diameter than the fuel pump inlet port, that hose has two different size ends. Has anyone recently had to replace this hose, and if so, where did you buy it?

Thanks muchissimo for any input. I'm buying two of them when and if I find them.;)

Nobody seems to know about this little gem?? I e-mailed IAP and I've looked over all the websites even in the UK, and I don't see this hose listed. I e-mailed Ruth Ann at AlfaParts this afternoon. I KNOW she'll respond, even if they don't have it.

Nobody's run into this before? The over-the-counter fuel line hose I have fits either one end or the other, but not both! I've split the internal reinforcement braid on hose like this before by lubing up the tight end and forcing it onto the fitting, so please don't tell me to try that. It's going to get fixed right, even if I have to dig it up myself. Or maybe fashion a close coupled reducer nipple.

And then I'll post the results on the BB.

You may be surprised to learn that the original equipment tank external fuel filter has a large (1/2) inch inlet to match the hose from the tank and a smaller (90 degree) outlet (3/8) to match the input to the secondary fuel pump. These filters are no longer available, except perhaps from an auto disassembler.

Just get a 3/8 fuel hose from NAPA, apply a bit of grease to the 3/8 hose and after heating it in hot water for about 3 minutes, so it will not "split" and twist it on the tank outlet. It fits nicely on the replacement filters available.

I have a used one that I can still blow through, if you are interestedd

Just my 2c

Thanks Rusty- I appreciate the offer. If the used hose is ok with no splits, I'll sure take it for now. Just message me and I'll get you my address.

Per IAP and Jon Norman of AlfaParts, this hose is no longer supplied. So, I'm coming up with an assembly that should fit into the space and I'll post the info and a photo when I get it put together.

Thanks again.

Sorry, I don't have the hose. My shaped hose from tank to filter was totally trashed, causing my car to stop running after about 5 miles. What I have is the fuel filter I took off with both sized nipples. I can't attest to its usefulness, but I can blow through it.
I replaced it with a fuel filter from NAPA, with the same girth, but two 3/8 inch nipples.
I used a 3/8 NAPA fuel line hose, cut it about 6 inches too long and looped it above the filter, to accommodate the otherwise formed original hose to prevent a kink. Used a grease to lubricate and hot water to soften the 3/8 hose and twisted it over the 1/2 inch outlet nipple.
I don't know how long the old oem filter will last, but at least it should last a while. You are welcome to it.
Using the currently available fuel filter for the spider, again,you need an extra length 3/8 hose (or the metric equivalent braided hose) to count for the lack ofthe 90 degree exit nipple on the replacement filter currently available.
To run from the filter to the pump, which has a 3/8 inch nipple.
Contact me off line,if you want me to send you my old filter.
Rusty
