Hey everyone, after previous posts about hot start problems i have checked the injectors. They all spray at an angle but don't leak. So i will replace them anyway but from what i gather this will just cause a rougher idle and not the hot start prob.
After checking old receipts i see the acummulator has been replaced a couple of thousand miles ago.
So i figure my best bet is the check valve?
I have a 1984 na does anyone know if this is the correct part?

If not could you recommend where i can get one as i can't find anywhere in the uk

Thanks

It certainly looks like the right part, but the price...!

P.S. it could also be a leaky pressure regulator valve in the fuel dist.

...and it's always worth checking the accumulator for leaks (undo the tiny screw in the bottom).

Ok thanks, yea does seem a little pricey for the Check valve, GSF (German Sweedish French) told me it would be £4.65 but it would take over 2 weeks. I have the part number as being 911 608 140 00 but that ebay one says 944 608 951 01. They seem to harder to get hold of than rocking horse sh*t in the UK.

I will check the accumlator anyway just to be sure, before i saw the receipt saying it had been replaced GSF quoted me £49.99 for a new one, it seems really cheap to me but they seem to have the part number correct. (931 110 140 00).

If its none of the above i will move onto the pressure regulator valve.

Cheers

Are you sure they quoted you for the right part?

I bought one from GSF a few months ago and it cost £108!

Price on the check valve seems about right, I paid around $30 canadian for one from a Porsche dealer a few years back. 50 quid is a good price for the fuel accumulator.

It seems i should have ordered when i had the chance, I phoned back for the check valve and was told it was £9.85, i pointed out i was told £4.65 previously. I was speaking to a different person and they checked... He told me it was a mistake and £9.85 is the correct price. I'm assuming the previous assistant quoted me the price they pay or something. I didnt ask about the accumulator but i guess it the same applies. So £108 would seem about right.

Dont forget to check or replace the seal in the pressure regulator in the fuel distributor.
On the NA it is a small 'O" ring. 911 110 936 00

it never rains it pours eh?

I jumped in the car last night to put it up on ramps and there was nothing when i turned it over...turns out the starter motor has gone, probably due to all the cranking with the hot start. I have one on the way from ebay..

So i jacked it up, poked my head under the car and saw the Banjo bolt to the check valve was totally rusted and i can't find the part no for it, i looked in the parts catalogue on the "sticky" and it doesnt seem to show it.

Yea sorry terrible decription, yea i mean the Banjo coupling at the end of the fuel hose, having said that the cap nut isn't in great shape either.

The cap nut can normally be removed even if it's quite rusty, and then cleaned up. Smoothie has managed to find what may be a source of new cap nuts.

The banjo coupling on the end of the fuel hose can't be separately replaced; you will need a complete new hose. I got a replacement made at a local hydraulics specialist (not cheap - £35).
