Outer Limits 4x4 Board

hi guys
i have a td42t turbo gilde kit my pump is leaking like a siv i need to get a new pump what pump should i go for and what mods should it have.
Im running 15 pound boost on a stock pump looking for more power not worried about fuel consumption as only a weekender and comp truck i was thinking of a gu pump modded but need some feed back on what i should go for

Thanks Brett.................

PM Andy Diesel Tech.

Can you see where it's leaking from??

Just get yours rebuilt with a 12mm delivery valve upgrade and possible boost compensator for low down fuel control.

i would contact AG Diesel in melbourne they have the best comp spec pumps going around they done more than other and alot of boys from interstate send the pumps down to them...

Speak to Ozzie....

yeah its leaking from the back plate where all the lines come out of it


yeah i mite have to send it away as the guy neer me said no there is nothing you can really do to them to make them better

keep any more sujestions comming

thanks guys

Sometimes they leak from the small diamond shape side cover. Caused by a o-ring thats gone hard.

That happened to me once, I pulled the plate off and replaced O ring for 50 cents.

yep the same thing that happen to mine ive just finished putting mine (like now) and i think i have it out one tooth its wanting to go, i move the pump anti-clockwise and that improved it but still no go??????

Can you see the ZZ timing marks on timing gears? If so the single Z goes between the ZZ obviously.

who is your local guy that said this?

i know West end Diesel do an upgrade, with larger plunger and aneroid it was where i had mine done

You guys that are rebuilding pumps with up grades what sort of money are you looking at??
I am in a simular situation. My pump leaks on and off. Also running 15psi. Pump is maxed out and no more go untill I upgrade the pump.
Have found that the guys at Chapmans dyno tuning very helpful so far with tuning. They said they can do an exchange Reco Gu pump for $1700.

The GU pump has a 11m plunger?

Not sure.. If it does not, I know plenty of guys who have had the GQ pump rebuild with a 11mm plunger put in for under that price.

Its then good for about 130-140rwkw.

yeah ozy1
the local guy here was reliable deisel in the shire and he is the guy that does all of turbo glides stuff so you would think that he could help but no good. he is fair on prices for stock pumps though but just wont do any up grades
