Cheers guys, used your advice to find this pump for the Capri 2.8: https://www.ebay.co.uk/itm/Bosch-Electric-Fuel-Pum...

@Wedgehead - it's the same item you linked, just found it a wee bit cheaper - thanks for the suggestion!

5 year warranty and between the two other options in pricing. Will let you know if it's any good.

Cheers,
J

Well, it's in! On the bright side seems to be working fine. On the downside, does not seem to have fixed my hot start issues. To recap, so far i've:

Replaced all the old bent/eroded hose with new hose.
Replaced the fuel filter
Replaced the fuel pump
Had the mixture adjusted

Any other suggestions before I push it off the pier?

EDIT: Am having issues with my starter motor sticking too, so will replace that and see if it helps.

Best,
J

So...back to the start...was the accumulator okay?
If the car has sat for any long period then the metering unit could be gummed up...if so have you tried a full bottle of injector cleaner to half a tank...not a full one as it says on the bottle..run it for around 50 miles then fill up..It does sound like either something is expanding when hot..or there is some shyte in the fuel system...have the filters been changed?..the Cologne is sensitive to cruddy fuel!

Good news! Issue seems to be fixed. We'll see what happens in the future..
Basically was an issue with my sparkies giving up at high temp. New sent and we seem good to go.
Also took the advice to use a bottle of fuel cleaner, feels a bit sharper as a result.
120 miles to Bristol tomorrow to see if it holds together!
Cheers,
J

Predictably, another issue reared its head.

After about 45 miles, the fuel pump (brand new) started screaming, and the engine suddenly started cutting out when I was accelerating. Died in the middle of a roundabout.

I found a big leak in what i think was the auxiliary air tube (starts on the left of the engine looking towards the car and then comes down around the front and enters near the throttle body), so i've replaced that, but I don't think that in itself would cause the fuel pump issues,
Last thing i haven't replaced is the accumulator, so i'm probably going to replace that and, if it doesn't work, burn the car down.

Does anyone know if this will work?

You can bypass the accumulator and run without. It's a good test, even if you do eventually replace it.

I know! Some stty luck right.

I think it just had a myriad of problems that emerged when something else was fixed. The hot start seems fine now. The problem i've had the last few times has been the fuel pump coming under massive strain after about an hour of driving, so I assume that it's a problem with the fuel line and as it's all new piping and a new filter, i literally don't see what else it can be other than the acc.

Probably something else i've not even thought of though.

What does Tickover charge for a 280i injector? They won't sell direct to the US. How about Burton as well?

Mate...I hate to say this and I really hope it is not...I had a horrendous time of it due to rust in the tanks, the car started out okay when the previous owner decided to take it for a spin after being sat for 11 years...worst mistake ever!!...then gradually it materialised into contaminating the whole system...look up sacrificial TVR...yes...that was me...

The pump would act like this if the was no fuel getting to it, "Cavitation" as pointed out on here one day...have you drained some fuel from the pump feed into a jar to see if there is any muck in there?

Injectors have become available again, not a bad price...

You can remove the breather off of the back to see if fuel comes out... I think matey did this already?...can you see how your fuel lines are all plumbed in?...some of mine were wrong as the swirl pot was missing, someone had put a "T" in the wrong place and it was starving the pump...

Hey Ziga.

Thanks for the fuel warning. Fuel looks ok, had it all removed when pump changed. Tank does look a bit rusty when I look down the fuel cap though, so it's possible.

How quickly would your pump play up when you drove it? Mine regularly does short trips fine and only runs into issues after 50+ miles.

It varied in the beginning, anything from 30 - 40 but got progressively less until she was undriveable... this was after changing fuel, pipes, filters, rust is heavy so can settle for a while without being disturbed, another thought, was all the fuel hoses changed from the tanks?..what fuel are you using, 95 ron or 98 ron, were the hose ethanol proof?...it could be a hose collapsing internally..

The accumulator you posted is correct but save your money and try it without as I suggested a while ago

Hmm does sound scarily plausible. What was the cure on your end?

I replaced all the hoses stuff from TVR parts and got a new filter, so hopefully i've only fked my pump even if it is a rusty fuel issue.

Stick a coarse 100 micron pre-filter before the pump to catch the big bits.

I bought a cheap (£4) one off the flea which is transparent so you can easily see if it's crudding up.

Interesting. Did it work without restricting flow too much?

This the sort of thing you used? https://www.ebay.co.uk/itm/UNIVERSAL-Chrome-Glass-...

I had this rust problem with my earlier TVR “M”. —I solved it by dropping magnets into the fuel bowls until I had the tank taken out and lined/repaired. “IF” it turns out to be rust (anc even just precautionary). You could attach a magnet to the bottom outside of your tanks—couldn’t hurt. ‘ IF” you have rust the particles are can be very tiny like dust literally.
