fuel sending unit and pump

[raymond greene]

I need a new one and I see several on EBay. Delphi for one, for $320 including gasket and strainer. My GM dealer wants $600 plus for one. Ecklers list a separate one for the ZR1. Whats up? Tks[-X

If you do a search for fuel pumps, you will see an old thread where an updated style Bosch unit is modified a little for use in our cars. I did that three years ago and have been pleased. I don't believe the new pumps came with gaskets though.

If Jerry's got it, I'll second that.

The ones on Rockauto.com are fine for $20 ea.
PERFORMANCE ELECTRIC Part # P240KC
They fit with no cutting the holder.
Just replace both while in there and do NOT ever run the pump in open air. It damages them. Don't ask how I know.

Look for BB 454 Suburban pumps. They're the same thing. I would try the Bosch units if I needed replacements.

[Paul Workman]

I and several others had issues with the Airtech units, listed at AutoZone as the replacement for the pump. FYI.

As an aside, at 40k miles I replaced my fuel filter (located on the frame, behind the right front wheel) the same time I replaced my fuel pumps. I was shocked at the amount of crud that was in there!.

Paul,

Great point! That and the "socks" on the pumps. Sometimes they are plugged to the point where the pump is sucking up the socks impeding the flow of fuel.

[scottfab]

I agree. The strainers should be swapped out too. Most pumps come with one. =D>

Scott, Are you currently using these or know someone who is without any issues?

Scott,

Thanks. That's exactly what I was talking about. As the strainers get clogged the pump works harder. I'd suggest this could be a reason for premature pump failures.

[raymond greene]

Thanks guy's for all your help!:saluting:

Yes, I have two of those in mine car now. BUT I also put in a switch to activate pump #2 at will such that if pump #1 fails I can get home using pump #2.
Way back when I first got the car in 97 I had pump #1 fail.
The symptom is the car starts fine but will only run about 30 seconds (until the pressure drops in the rail).

I noticed that also.....does not jive with his TAG.....:D
Oh...wait...the LT5 is NOT modified by the switch.....so he is still OK :cheers:
Just some friendly ribbing ;)

What is the source of these filters?
Thanks in advance :thumbsup:

http://www.zr1netregistry.com/Portals/0/Images/TechArticle/FuelPumpReplace/MVC-220F.JPG

I notice two different filters on fuel pumps on right and identical filters on fuel pumps on left (the black rubber clip is missing).
I assume these filters on the left will not fall off?
I assume both filters except the bottom one on right are kept on solely by friction fit of metal cup on the plastic?

+1 there...

DO stay away from AirTech.

I put one in my '98 GMC, against others' advice on GMC boards (because I keep tank FULL - which IS supposed to make a difference), and it failed post 2 years < 10k miles.

Yeah - but I'm special.

No, NOT special ed (as far as you know).

What the HELL is your problem :p
Kidding...... ha

Many that have been around since the 90s know that I have MANY mods to my car. In fact I pioneered some and ALL are well documented in my FSM. To be sure all are easily removed except the Corsa exhaust. I kept the original exhaust. Again, there's nothing wrong with mods or even trashing the car if you want to. Talking others, especially newbies, into doing the same without presenting alternatives is what I have an objection to. And I sure want to be able to use "I disagree...." or for the more sensitive folks "I beg to disagree..." or "I humbly disagree...." etc. when I want to present those alternatives.

It's all about respect, giving and receiving.

[Dynomite]

OK :sign10:
