Hose Brand Help

Gerry,

I've been running into this specific problem more and more on some of the 328's I've been servicing, as of late. The hose in your picture is an OE one and it seems that they now came in 85mm lengths, versus 100mm as I used to receive from Ferrari in past years. It is common to have poor alignment on the "crossover tube to RHS tank nipple". I've had some 328's where they line up perfectly, where others...they're not even close, or the OE rubber sleeve just covers the tank nipple! Very scary!!

I've been using a "wet marine exhaust/fuel transfer" hose for many years now, with good results. However, with the fuel quality/alcohol content now ever present, I still change these cross-over lines out every five years, regardless of visual appearance. If you get into a bind and need these hoses, I can supply them in (100mm lengths). With the crossover tube loosened and centered, two 100mm hoses "should" fit just fine. The hose I use is the correct i.d and doesn't have that "wire" embedded...

PM me if you need help...

an alternative hose is the napa #1030 which is 1 1/2" id and can be purchased in 1ft. increments.
it is slightly larger than oem, but with 12mm wide norma or aba hose clamps it works well.
if you are really concerned, you can use 3/4" wide t-bolt clamps.
this hose is made by gates specifically for fuel filler hose and transfer piping use.
while long-term suitability with ethanol blends is important, gates most likely is addressing that issue.

 

Agree completely! The aluminum tubes and nipples are 34mm which is extremely close to 1.375". The larger hose (although readily available in 1.5"), even with "heavy duty clamps", in my opinion shouldn't be used.

And yes, the factory hoses are expensive...as well as some of the premium "marine grade" or "specialty hoses", but there's just too much at stake here not to do it right.

Good luck Gerry and please let us know how you make out with the Factory providing the hose in adequate lengths. As I mentioned before, I've had a few 328's in for service lately, of which one could use the now provided 85mm length hoses. The others, due to varying lengths of the tank nipples and cross-over tube, required longer rubber hoses.

Regards,
David

 

My 328 requires a longer hose on the RH side too and it baffeled the dealer too.

The hose I used is this Thermoid brand , it comes in 1 3/8" Dia. and it has no wire. It worked very well.
Previously I was able to get the stuff with wire on, but the last time I did it I couldn't get the wired hose on?
I called the company and they recommended someone who had some.

If you have to have one longer on one side you can get one for a Testarossa that connects the tanks and cut it to suit your needs.

 

I used both the Gates "VulcoFlex" and the NAPA equivalent for nearly three decades for this purpose without difficulty.

 

Sorry to hear this, as Gates Vulcoflex is a specifically designed as a coolant hose...and not designed to handle fuel. I just pulled a piece of "Vulcoflex" off of a client's 328 that was used on the fuel crossover tunes, as it was swollen up and gummy.

Probably not the best thing to happen considering where all that "gummy rubber" ends up...

 

With modern formulations even FUEL rated hoses are not holding up......

Go with marine rated fuel lines......they move a lot of fuel, so will have larger sizes.
