Hi all,

I want to press the button on ordering a full set of fuel lines. Reading past posts it seems these are the choices/problems...

  • Porsche - my first choice BUT seems like its an impossibility to do the 'through body' connections, at least one engine line is NLA, mixed info on it's ethanol resistance, and potentially the stock is old
  • Paul Mason - nice teflon kit BUT connectors are imperial, problems with fuel filter fit, potential nightmare with feeding hard lines into body
  • Griffiths - believe they only do the main 3 engine lines not the through body
  • Len Cummings - not come across anyone on here that has used full set, only part (through body lines)
  • Have custom set made up - Pirtek etc 

I'm therefore tending towards Len Cummings, mainly because reading the excellent thread by @Chris_911 it seemed to be his final thought on the matter. I think @Ian Comerford also bought the Paul Mason kit...did you end up with the same problems as Chris? I'd rather not go the custom set route mainly out of laziness sourcing and measuring etc.

Any other advice or recommendation? Any others looking for a needed winter project to avoid an unwanted BBQ next summer, if so I'll enquire re discounts.

I can’t offer any advice on which to choose. (only that I’d prefer Len’s kit.)

But I’d be interested in a group buy if you could arrange something.

I think Len Cummings gets plenty of good reviews on Pelican for obvious reasons and seemingly does great backup in the event of problems.  The other option is taking your old pipes to an hydraulic expert and having them copied/remade with Ethanol resistant pipe.  After having to get a pipe remade as the supplied option was no good I found how cheap it is.  If Chris kept his old pipes maybe you could borrow them

Thanks chaps....looks like Len Cummings is the route I'll go then. I'm going to enquire re the full set, front to back. There is a steel line (pressure) going into the engine filter which I won't touch (hopefully), but the return line from here is another rubber crimped on to a steel line - see below. It looks like Len does this line as a flexi so not sure I'm happy replacing a hard line here with a flexi, not sure what people think? Likewise not sure what Len's engine lines look like, especially the more complex one to fuel rails as that has a hard line component too. Maybe the only way is to mix and match with Porsche and Len's lines. Getting all this right seems surprisingly hard.

I'll let you know what comes back Russ. Anyone else interested give me a shout.

I still have the more 'complex' engine bay pipes in my garage.

There are some aspects of the Paul Mason kit that I bought that I REALLY don't like - with hindsight I would never advise going that route.

I will probably get these old pipes re-made and fit those at some point.

Agreed

Interesting thanks! I've seen a few of that chap's videos. Again I think it makes the Len Cummings set up look good as you use the old lines to pull through the new ones with a coupler. Presume they were Porsche ones in this video - once I hear 'you need to drop the crossmember a bit' etc etc I start thinking this is beyond my skill set. And of course at this stage you've snipped lines so there's no way back, leading to my 3.2 becoming an ornament on a lift for the foreseeable future.

The Len Cummings tunnel lines were incredibly fast and simple to install. The coupler works REALLY well.

Hello Bob

I would also be interested in a pair of the tunnel fuel lines for my 3.2 if ordering from Len Cummings, depending on availability and pricing.

For the rubber/hard return line that goes from the tunnel through to the engine bay I think I will probably buy a genuine Porsche line rather than use a fully rubber hose.

OK noted Anil. I'm in communication with Len, and also banged out an email to Porsche to get a list of what lines are actually available front to back as I'm with you in feeling uncomfortable replacing a hard line with rubber, Len has a potential solution, so I'm just gathering up all potential choices.

I totally agree Ivan with your last sentence and I'm pretty sure the tunnel lines will be ok because others that have removed them have commented that theirs were in great shape. The problem though is that they have rubber lines swaged on to them at the front (from the pump and to the tank) so that those rubber lines can't be removed. Len Cummings lines can be separated at this point. I'd like to replace all the 40 year old rubber lines to avoid what happened to poor Frazer. All the other lines (bar one) have rubber parts to them.

Did you fit his tunnel lines to the Mason ones then?

Ive done a few sets of fuel lines recently and the rubber section from tunnel to pump / tank looked ok in situ but have all been cracked and well on their way to failing once removed and inspected in more detail. As noted the rest of the plastic part has been pretty much perfect.

Can't see the logic in not replacing ALL the lines. They are all in excess of (a minimum of) 34 years old now.

Did you use Porsche parts @jevvy?

If so, are they E10 compliant?

Cheers

Long thread here: 

 

Thanks @Chris_911.👍🏻

I had already read your superb thread where you said you’d used Paul Mason lines, but I was confused as earlier in this thread you said you’d fitted Len Cummings tunnel lines. (I’d missed the bit where you said you ordered Len’s tunnel lines)

Sorry for my mistake.

Regards

Russ

Yup bought direct from Porsche.

Yes, apologies for the delay...I've been whacked with a winter bug. 

Len Cummings is a pleasure to deal with over email...very helpful. He's a retired chap who used to run a garage making this sort of stuff....here's the info I've got from him...prices very reasonable wrt Porsche and hoses definitely safe for ethanol....

Front:

Supply Hose, 12mm, Tank to Pump $  25
Constant Tension Clamps, (2) $5ea $  10
 
Front Hose, Feed Pump to Tunnel $125
Copper Crush Rings, 12mm, (2) $2.50ea $    5
 
Front Hose, Return, Tunnel to Tank $125
 
Tunnel Lines, (2) w M14 Male Cone F&R $125ea $250
Grommets, (4) $8ea $  32
 
M14 Female Coupler  N/C
 The M14 Female Coupler is included at N/C. This makes for a much easier repair and saves a great deal of mechanics installation time.
____
$572
 
Middle:
 
Typically, this all that you need for the chassis except for the short length of Hose on the Return Hardline at the rear…
I offer this as a repair piece you can install yourself at $65 w/ a Norma Clamp. There is no issue using the clamp, as the Return is low pressure and Porsche has used these Norma clamps on their low pressure hoses for generations.
 
In case your rear Hardlines have rusted or need replacement, they are NLA from Porsche. I offer them in E-85 Rated hose as follows:
 
Rear Feed Hose*, Tunnel to Filter $165 *Requires a Custom Machined Female Flare Fitting
Adapter w/ Copper Crush Ring $  22.50
 
Rear Return Hose*, Motor to Tunnel $145 *Requires a Custom Machined Female Flare Fitting
______
$322.50
 
Engine:
 
For the three engine lines he rehoses your original hard fittings.
 I offer a "Re-Hose" of an original 3.2 Main Tee assembly, YOUR original. I do not offer the steel Tee part.
 
This means you send me your originals, I strip and send them out for Yellow Zinc Plating, then fit new E85 Rated Hose from Cohline in Germany.
 
Sadly I see this part as a ball-ache. So think if you go this route it's best to do tunnel lines only through Len and try sourcing rest via OPC??
However I'm presently wondering if its best to get the lot via Porsche having read @jevvy post above.
