Fuel pump, dmc

[DMC-81]

I apologize, perhaps I took that thread differently. From that link, I got the impression there were some who had experienced failures and went with different pumps but overall the experience had been good, with Dana stating he's had 7 years of service on his.

Thanks Dan.

We should be measuring mileage, not years.
I put on up to 20,000kms per year on my car. I know this is more than some deloreans get in a decade.

Good point. Most whole car warranties are X years or X thousand miles, but every part I bought for any other car was stated in X years.

That being said, I appreciated hearing the macro experience with this pump solution from the above quoted thread:

Marc, if you (or anyone else for that matter) are reliability issues with the pump that comes with the 107000, please let me know and I will help.

We've sold over 1500 of these units since 2012 and we've installed more of these than anyone else at our locations. If there are widespread failures of the pump itself, I *really* want to hear about it because we're not seeing it. Between 2014 and now, we have sold 14 replacement pumps (less than 1% of overall sales). Of the pumps/in-tank filter screens that we have been able to get back from customers who got replacements, all but two were due to debris in the fuel system causing pump failure. My supplier is very eager to see any failures, and we are, as well.

BTW, I'll be coming to the Spring Social in a few weeks, and I'm happy to talk with you about it there.

Although I don't drive many miles, I do drive the car almost every weekend...all year, a benefit of Florida weather. The downside is long hot summers, and lots of traffic in Central Florida. So, I do clock engine running time, half of which is during hot weather.

During my time with my fuel pump, I have been reading about the pump issues, new style and old style, and to me mechanical empathy applies, whether you opt for the old style, the new module, or an appropriate GM pump:

1) Install it properly, in a clean environment. There was one poster that said that his similar GM pump lasted just a week or two in his Blazer because of contamination.

2) Try to mitigate our characteristic fuel heating problem. Several tactics are discussed on the forum. For me, I just put some thermal shielding on the flexible supply hose where it is adjacent to the hot coolant pipe and the exhaust manifold (near the fuel filter), and the fuel filter. Plus I try to keep a full tank as much as possible ( e.g. what's takes longer to heat on the stove... A small saucepan of water, or a big stock pot of water...same principle). These have worked so far with my situation.

Cheers,
