Ah.....I have noticed that if I turn the key on and off a few times, this seems to help it start. Sometimes it'll crank and crank, then with a quick flip of the key on/off a couple times it starts right up!
I was under the impression that it has a new fuel pump installed in it. Maybe new just means "different one" - I dunno.....
I don't know exactly how quickly the pressure bled-down - for sure within the5 seconds it took me to get out of the seat, and to the rear of the car. |
Supposedly you're supposed to have a drop off down to 20 psi after 5 minutes, and then it should hold that 20 psi for at least a half an hour.

This pump check valve you're speaking of. Does it look like a little round "disc" on the front beam? Or is this internal to the pump itself. I checked and the car does have a very new looking/clean pump installed in it.
I cannot find a reference to this in the Bentley. Is this it?

That's the fuel pressure damper. Can you show us a picture of the pump?

You don't see any reference in Bentley for the check valve, because it's built into the pump.
The round disc shaped part is the fuel pump dampener.

| The check valve is internal as posted. It's inside that shiny "top hat" sticking out of the pump sideways at the fuel line end. |

As has been advised, I am planning to replace all of the fuel hose. I did some searching on the samba and there have been a multitude of threads on this subject, and there may not be a definite answer. First, the size seems to be about 5/16 from what I am reading. That is just under 8mm. Most supply houses that I find list the fuel hose at 7mm. If I wanted to stick with a German brand, would 7mm work, or is 8mm closer to the actual correct size?
ISP West and Bus Depot both offer German braided high pressure fuel hose, which I like because it will look original, but there seems to be mixed feelings on safety/quality/longevity. Any thoughts on this hose? |

I used 5/16 fuel injection hose from the auto parts store. It works perfectly.
Unless you're entering the car in a judged show, there's no need to worry about the appearance of the fuel lines.

Exactly. Same applies to the fuel pump.
When I plumbed my wife's car back in 2008, I used standard 5/16ths fuel hose. I replaced all of it at that time. I used a 25 foot roll of the stuff, along with 34 FI style hose clamps. I haven't noticed a problem with it yet, but I might take a good look once it warms up and dries out in a few months (it is almost 10 years old now). However, I also used an Airtex E2000 fuel pump on it, as the old Bosch pump was long gone. I moved the new pump to the center opening of the beam to get a nice lazy bend in the feed hose, due to the added length of the pump.
Keep in mind that a lot of the guys are now going to dedicated FI hose, due to the mix of fuels being available. Some of the cloth wrapped stuff isn't really compatible with the newer fuel blends. It's a little more expensive, but it does give a piece of mind that it'll last a while longer than standard fuel hose.

| I am trying to make the car as correct as possible-I did spend the money and effort to get the correct type fuel pump, and would prefer the look of the original fuel hose material, but certainly if it is not safe I would prefer the modern stuff. |

On my '67 Mercedes 230 I used 5/16" Gates Barricade hose and covered it with a nylon braided sleeve commonly used for wiring harnesses. It takes a little extra time, but the results look much better than having modern hose in a vintage car.

| VWfreek61, that looks good and seems to give the best of both worlds-modern safety with vintage appearance. Do you know the size of that covering? |

That's a great solution for those who want their car to "appear" stock. You'd really only have to do the engine bay, as the rest is hiding under the car.

I don't remember the exact size because it's been a couple years, but I think it was 1/2".

I used this 5/16 hose from Amazon. cost $20 for 25 feet. Sure beats paying $3 a foot from the local auto parts store.

Just so you know that's not FI rated hose, but it can be used on our cars as I mentioned above. On my wife's car, I used the 30R7 version of it, versus the 30R6.

I am back at it - working on this fastback.
Last we messed with it it was running okay, not great, but since we replaced all the fuel lines and everything in the brake system we decided to take it for a ride (1/2 mile) to fill the tank up at a local gas station. It actually rode up there pretty good, but wouldn't start back up. It was flooding horribly. Finally did get it started back up once we towed it home and it sat for a few hours - it took a lot of cranking!
Anyway, since it was leaking oil from what I presume was the oil cooler, I pulled all the sheet-metal, replaced the cooler with a refurbished one and did the seals. Next step will be to try and troubleshoot all the FI stuff one by one and see what's working right and what isn't
So - what the hell is this thing? I can't find a reference to it anywhere. Not in the bentley, not on sites which sell FI stuff, etc...
It's obviously broken, both by site and I get no continuity through it when tested.
It was getting power from the coil attached through an in-line fused link.
