Porsche 911 TV engine fuel diagram 1973

[misho]

Hello

I would like to ask, which kind of the fuel filter is correct for the TV engine? (Carbureted T 1973 F model europe version, engine number 6530001-6533239) Is it fuel filter bosch 901 110 232 00_? And also how fuel diagram looks like? Have somebody fuel scheme for this engine?

Thank you in advance

I am confused. I thought all 1973 911's has either MFI or CIS fuel injection.

That looks like a MFI filter set up. There is a list by Grady Clay that shows the plumbing.

Do you have the stock fuel pump installed as well?

Euro T's were carbs in 72 and 73 I think.

Cant answer the question but I bet someone from our host could.

I would post this on the Early 911S Registry BBS. A search there may also answer your question.

TV was the European 2.4 911 T with Zenith carbs.
The picture is for the MFI filter and primer.
Low pressure pump would be used on Zenith along with inline filters.

As Flat6pac stated, the RoW '72 & '73 T-V had Zenith carburetors (V for Vergaser). Only the US spec 72 & 73 Ts had either MFI or CIS (73.5) to meet emissions.

If you look at illustration 201-15 in the '73 PET catalog, you will see a diagram for the fuel line used for the T-V cars. It is simply a line coming from the rear fuel pump, and splits to each carburetor. There are filter screens at the input fittings on the Zeniths.

So there is no fuel filter between rear fuel pump and Zenith carburetor?

So I guess for the OP the real question is to find out if he has a true Euro T or a conversion.

The OP should tell us what Carbs are on it.

I would think the engine numbers stamped on the case would tell the tale. Looking at my PET, the serial number would be 653xxxx and the engine number would be 911/57 or 911/67.

Yes, engine s/n would be 653xxxx for a '73, but the T-V engine Type should be 911/57 or 911/67 (Sporto)

This is my understanding, other than the filter screens at the carburetors (also, perhaps a screen at the tank outlet). However, I would like to see an original T-V to confirm this as I received my '73 T-V without the engine, so I have no reference other than PET.

All fuel filters mentioned in PET for 73 & 73 are listed as applying to; T (MFI), T-K (CIS), E, or S.

I agree, that it would be nice if somebody with a RoW '72T or '73T could post a photo showing the fuel line routing in the engine bay.

Thanks for catching my typo. Corrected.

Hi, from a row 73T owner (euro spec)!
Those car has not any fuel filter, the only filter should be in the fuel tank.
In the engine bay the fuel routing is provided as misho posted image from pet.
The fuel outlet is connected with a rubber hose to a fuel coupler (made of brass) and then to the carbs (zenith)
....
If you need pictures just ask!

[frankc]

I was fortunate to find a NOS part #3 (901.108.051.06) years ago since I believe they are now NLA. I can post a photo of the part if anyone is interested.

A better diagram showing how the carburetor fuel line routes to the fuel pump is shown in 1969 PET illustration 201-02 (part #26 in the diagram below).

A picture would be wonderful. In particular, I'm curious how the fuel line is anchored in the engine bay. I have to believe that it is anchored to something to prevent it from moving around. Is it tied down to the upper shock cross-member using the same tie-downs that hold the wiring harness in place?

Thanks

[misho]

Some pictures from engine bay and fuel tank would be very helpfull.

Hi misho, hi all,

I hope you can excuse me but i was very busy and away from home so i haden't the opportunity to take the photos you requested... i hope i'm not toooooo late.






As told there is no fuel filter, fuel line come into the engine bay and then goes with a rubber hose to a couple that serve carburator left-bank1 and rightbank with two different hoses.
The brass coupler is simply plugged with two clips.

Hope those photos are ok... if not just ask for details !

looking froward to hear from you

[frankc]

fizeus,
Thank you very much for posting those photos. This is exactly what I was looking for, and hopefully it helps the OP as well.

I see that the metal tabs on the cross-member are used to tie-down the fuel line. Interestingly, my '73 only has the one tab on the left - there is no sign of a right tab ever being there (the engine bay still has the original paint). I'll post a photo later.

There are other areas of the car that I am interested in seeing photos (there aren't many T-Vs here in the US). I'll send you a PM so as not to hi-jack the OP's thread. Or maybe we should start a T-V thread .

[fizeus]

Be careful when you work on the metal tabs... and try to use two wrenches because they not bend... they broke (easily!)

If you need other pictures feel free to start threads or send pm!
I'll be happy to help!
