328 fuel hose search--frustrated!!

OK, I've been through lots of threads here, researching what I need to get to replace all the rubber fuel hose in my 87 328 GTB. Bought the car last month, parked it soon after because of the fuel odor in the garage. I had a 77 GTB previously and replaced all that hose, but the FI cars seem a bit more complicated.

One thread here posted sizes and lengths needed to do the job, I'll paraphrase here:

145" of 5/6"--ordered some on Ebay, FI-rated
37" of 5/8" (CANNOT find this stuff!!)
--I did buy some at a marine supply, rated B-ACOL USCG B2, SAE J1527--but I then read on here to NOT use this on a car!--it's to connect left tank to pump, so it's not under high pressure, right?
29" of 1/4"--ordered some on Ebay, FI-rated
8" of 1-3/8" (for the crossover tube--ALSO CANNOT find this stuff)
4" of 2-1/4"--(for the filler nozzle-to-tank; found the NAPA 1055 no problem)

Does this sound correct to the experts out there? I know Scuderia Rampante/Ricambi offers the partial kit, but jeez it's expensive, and it only covers 3 areas. Hoping to find alternatives..

I'm considering returning the Ebay FI hose when it arrives, if it doesn't meet spec.

After further research, in an effort to purchase hose that will be resistant to all the new methanol blends out there, I've found the SAE 30R9 standard. Goodyear has this product, check this link:

However, I can't seem to locate a dealer that may carry this product. There is one guy in Houston I've spoken to, but he wants me to buy the whole 25' roll or nothing!

I know Verell sells a kit to replace the small plastic CIS lines, haven't heard back from him, although mine look fine...

Does anybody have any helpful info worth posting here, for myself and others?

One more thing--for my previous car, 77 GTB, I bought the crossover pipe sections (1-3/8") from Superformance UK, but their website shows those bits only for the 308, not 328. Shouldn't they be identical?

And Greg when all the new stuff "goes Noodles" on you in a short period of time, then what are you gunna do?

Your plastic lines ARE BAD. Period.






You know who to contact.



"Just Do It."










Disclaimer: I have NO interest in the final outcome.

 

Ah the joy of working on a mid-engine '2lb's of **** in a 1lb bag' fitment, I must have thrown $50 worth of tools into the bayou when I attempted that feat. Persistance and beer are you allies.

 

You only drink WHEN working on a friend's car.


You drink only AFTER working on your own.

 

If the measurements are converted to Metric (ah ha) we end up with 16mm and 35mm hose that you are looking for, try this:

or:

Silicone 16mm here: (also braided)

If you mean Verell, I have sent him an email regarding his CIS kit. I will indeed purchase that. The mystery I'm trying to solve is where to locate the stuff NOT in the SRI kit. As I understand it that kit does NOT contain all the hosing post fuel pump, is that correct?

If I have to purchase the SRI kit, I will indeed do so, but before I drop $400 on 4 pieces of hose--and I do understand and respect Dave Helm's efforts to make that stuff, I'm going to explore alternatives, that meet the current standard.

The stuff I need to locate quickly is--5/16" and 1/4", SAE 30R9 standard. I need to for sure replace the cloth-covered hose across the top of both tanks. There is for sure fuel odor and wetness on that one. Any links to a source? USA preferred...

Greg

 

This link is SUPER awesome, thanks. I've actually been to that site, but that hose is marine-grade. I always understood marine-grade has to be superior to automotive. Can the experts once and for all settle that question in my mind? Marine-grade J1527 is OK to use on my 328?

Remember I do have a section of this J1527 stuff in 5/8" to connect tank to pump... OK to use in this manner?

Greg

 

Greg,

Give DaveH a call.


He'll help.

 

I am an amature internet researcher so please use due dillegence when using these refrences. I am not a fuel hose specialist. I am sure someone will chime in after checking out the sites.

 

Crowndog,
Are you able to confirm that the metric measurements 16mm and 35mm are indeed the correct sizes for this application? I'm going on a post by somebody else on here--no reason to assume he's wrong, but I'd hope to order and have on hand all the correct stuff to install the same day I tear the car down.

16mm for tank-to-pump and a few other places

35mm for the 2- 4" sections on the crossover pipe.

The OE parts table doesn't seem to give hose sizes, just generic terms like "pipe" etc..

The other persistent question--do these hoses, which aren't under high FI pressures, need to be FI pressure-rated?

Greg

PS--oops, just saw your last post, before I posted this. Can anybody else confirm?

 

All I did was use a conversion chart given by a hose manufacturer. I double checked with a conversion calculator and those figures are correct.

The second link gives you a choice of braided, low pressure or silicone
Cloth Covered email or call for quote/availability 918-760-0668 [email protected]

This cloth covered hose is designed for high pressure transmission of oil, gas, air, water, coolants, etc. where operating pressures do not exceed 300 psi. Oil and mildew resistant textile black braid. Temperature range: -40°F to +250°F (-40°C to +121°C). Great to replace factory hoses that are cracking. Use in places you cannot use silicone.

The fuel pump pressure off the pump for carbs is 4 -6PSI, IIRC it's slightly higher for the injected pump but not above 10PSI.....7PSI maybe??

The marine ratings are indeed for the use of alcohol fuel additives.

That's where Dave started, IIRC before moving on to tougher stuff still yet.
Cross it over to metric sizes and check the VW dealer over by the Mucky Duck.

I want to come by and see it!
Will call later.

 

Crowndog, thanks again for your info, very helpful.

I guess the question I'm hoping to get answered is, are the sizes mentioned, even converted to metric, in my first post indeed correct for the 328?
And, is current-standard marine-grade stuff OK for auto use?

Thanks BT, call me!

The hiperformance store is Greg Gordon from the Alfa side of the world. He has been selling hose for quite some time and is into turbo and supercharged apps of Alfas for many years. He is accessible via phone with questions. Great guy to do business with.

Best Regards,

Am I missing something here? The regulated primary fuel pressure in my QV is about 75 psi (5+ Bar), so the fuel pump working pressure output must be something over that.

 

Found some hose on fleabay:


http://www.ebay.com/itm/FERRARI-208-246-DINO-288-308-328-365-412-512-F40-FUEL-TANKS-HOSE-/230679590254?pt=Motors_Car_Truck_Parts_Accessories&vxp=mtr&hash=item35b593356e

 

No, only the hoses downstream of the fuel pump need to be "FI pressure-rated" (but, IIRC, there are really no flexible "rubber" hoses used downstream of the fuel pump on a CIS system -- only the flexible hard plastic Cohline type). The hose from the tank to the fuel pump inlet does not; the hoses in the fuel evaporation system do not.

 

Thanks Crowndog, I may have to spring for those... Is that price for 1 or 2? This stuff is EXPENSIVE!

Greg

 

A HA! Thanks Steve, I've not gotten under the car yet, so I was assuming it was similar to my old carb 308, in that the route from pump to the fuel system was rubber. Guess not.

So, are these hard plastic lines susceptible to rot/and/or methanol damage? Are they part of Verell's kit? He hasn't gotten back to me yet, I'll call him tomorrow...

I need to get the car in the air and really get to know what I'm dealing with... Just trying to order all that I need so it'll be on hand immediately..

Greg

 

The Cohline hoses are a solid polyamide material so I think that they are much more chemically-resistant than a flexible elastomer. The ones on my TR seem to be holding up well, but maybe on a 328 you might have some that are more exposed to the exhaust temps so might be a different situation. If you note any external cracking, I'd certainly replace them (and that is what Verell sells), but I don't think you need to worry much about the inside falling apart (like a multi-layer rubber hose).

I know the SRI (Dave Helms at www.****************.com) fuel hose kit (for all the other low-pressure fuel hoses) seems a little expensive, but it's way, way less than the F price, and it truly is "better" (plus you'll burn some of your time doing the sourcing yourself ). Another clever product (IMO) he sells for your model is a support piece to prevent the hose from the tank outlet to the pump inlet from collapsing at the bends:

Of course, there might be another source for those too, but time is money

 

That really is the best fuel hose I've ever seen. Probably be good as new even even after I'm dust in the ground.

 

That hose is $400 ???

 

The hose is part of a kit for $350. Also included are the filler hose, the crossover hoses and clamps. It's expensive, but unless its SR09 or better, I wouldn't do it.

Has someone priced with SR09 or SR10 hose with new clamps and coil reinforcements?

It would be nice to see the price comparison.

 

I know, it seems very expensive. If I have to I'll go that route, but I am shopping around.
