TD42 surge (miss) under acceleration

Steve, u r right on, had the same problem 2 weeks ago, had me stumped for a while- changed fuel filter ... no difference, removed gauze filter on top of pump, and now it goes like a rocket. I now also put additives in fuel and in farm fuel tank, u could actually see a greenish tinge on the gauze...... regards Ric

Thanx Steve,
Sorry, I should have mentioned i saw that whilst searching this topic a few weeks back. I had my mechanic check that banjo gauze and he reckons mine is actually missing, but I think I might look myself, having discovered this morning some of his previous 'handy work' and so called repairs, I am beginning to doubt his competency. i wish I could find a workshop I could trust 100%. God knows I pay a mean price for repairs, not bodge ups.. Thanx for the reply..

Gents,

Just pulled the banjo off and low and behold, the mechanic didn't lie, i don't appear to have a gauze filter there. I had a look in and fished pretty deep, there appears to be a spring (on it's side around a tube) on the inside, but nothing else I can see. Any other advice out there?? and also, how do i get diesel residue off my keyboard??

Thanx for that suggestion though, that's one ruled out..

G'day Ric,

I am departing Sunday 18th (god willing) and am going up NW Coastal to Carnarvon, then going to cut across to Karajini, then up through Marble Bar - Derby - GRR - Mitchell etc. as long as the roads are open by then, if not will be staying on Sealed until roads open. Main Roads still have 1/2 of GRR closed.

I will be in a silver SWB GQ (Maverick), sya g'day if u see us.

Interesting!!

With the little 'squid jigger' to remove the filter, it sounds like, from what you are saying, it's not possible to see the filter in the pump. i am wondering if I missed it. I had a look with a good light, and gently poked around with a small srewdriver, but didn't want to poke to hard as I have no idea what's inside. Should I have another look?? If it was a problem that needed an electric fuel pump, it should happen all the time, shouldn't it. i might just roll it down the street on fire...

cheers

I still don't appear to have one, i can see a spring inside the pump, but it is on it's side and appears to be wrapped around a pipe running horizontally inside the pump. I hope that's not the spring, i don't think so as it appears to be well fixed and not rattling around loose. I can only guess that if there was a filter there, it is way deeper than the thread depth for the banjo bolt, as i can see a fair way inside, certainly past the most obvious area for a filter.

The bizarre thing is, I have put it back together, bled the system and it 'appears' to have cured it. I am wondering if there was maybe a touch of air in the system, could that cause it, or I poked my screwdriver through it the 1st time and now have great flow. Being an intermittent problem, it will no doubt return tommorow, just on the test run, it showed no signs of missing at all, that is unusual.

i hope I am looking in the right spot for the filter.

Chris,

My banjo is pretty much on top of the pump, very easy to get to, i hope I pulled the right thing off, I just followed the fuel line down to the pump and found a banjo, looks like it has a screw in the middle of it, yeah its the right bit - I hope!!

Maybe it was a bit of air in the system, I am not sure what the symptoms are for that, but I would expect the service people would bleed it properley, surely. They put the filter on, do the servicing, i will be amazed if it was something that simple, but i hope it is. I'll let it sit overnight and see how it runs tommorow.

if it s not too much trouble, I would appreciate a picture of your pump, too see how much different it is to the GU, that would be great. Email to
2bukoo@swiftdsl.com.au only if it is no trouble.

thanx for the input.

Thankyou for that. I will check the whole line.

Cheers

Thanx Truckster,

I appear to have solved it, took it for a good run today and it hasn't come back, it sounds like maybe some air was in the system which is annoying as it was easy to fix. Annoying not because it was easy, because it has been a problem for a few months now and no one in the motor industry could cure it for me.. I never even thought of bleeding the system properly. Never assume a workshop will do the easy stuff..If it returns, i will try the clear hose and check everything through to the tank.

As for the injectors and pump, they will have to wait until I get back, I have thrown too much money at it in the last few weeks preparing it for this trip. I am happy they should be OK.

I will have to try and figure out who to take the vehicle to for the pump and injectors when I return. I just don't know what to do there. I go to one of the most reputable 4wd centres in my area, the majority of work is good, but i keep discovering small things that should have been picked up in basic service and also some work which had been fixed with thread tape and 'emergency' type repair which has really pi&&ed me off, as they know the vehicle is about to go away for some time. i will sort it out..

Anyway, thankyou for your input, the vehicle is running sweet now, I just want to get packed and head north.

Cheers

Maybe worth gettin checked BEFORE you go, would suck bum to have the fuel pump go fluff in middle of nowhere. you would root the queen mum at that point in time to have spent the $$ on the fuel pump!!

enjoy the trip
