It got worse and worse and Then it stopped and was stuffed. I installed a new one 18 months ago (through mechanic so a real one) the new one was silent for the last 18 months then two weeks ago the whine started again and is getting louder by the day. It's sounds exactly like the old one before it died. Feel pressure on my gauge seems the same (if the gauge works) So what's the go. (A) what is killing them so quickly(B) should I replace with a different brand that may be more reliable Mine is on one of the original PW surge tanks. I also love in Darwin and wonder if the heat is killing them. The knot think I recently changed is my injectors to KPM 1000cc from Siemens 60lb Link to comment Share on other sites More sharing options...

I cranks when I turn the key to acc and once primed it stops then starts once car starts. How can I tell. Also I have a check valve on it if that makes a difference.

You need to check the wiring. Link to comment Share on other sites More sharing options...

So what's the go, if it's running on low voltage it wears it out quicker? Link to comment Share on other sites More sharing options...

Does anyone suggest changing the pump to something else or should I stick with the 044 on the surge tank . I was thinking walbro 460 or dw300. I now have 1000cc injectors and would like the option to run e85 Link to comment Share on other sites More sharing options...
