Factory fuel pump or generic external pump replacement???

Post by Spike99 »

.

Within the Tips & Tricks thread, it was suggest that an Astro/Safari van owner should "proactively" replace their van's fuel pump at 100K miles. As implied, better to do it in one's dry / heated garage instead of needing a tow and hiring an expensive shop to do the work. If possible, replace the fuel pump at 100K miles and "be good" for another 100K miles.

Knowning that "factory" fuel pumps blow at more then 100K miles (on average), should one replace their van's existing fuel pump with another GM factory fuel pump, with an 3rd party "in tank" fuel pump replacement, or go with an external (aka: inline) electronic fuel pump replacement instead?

Thanks for your fuel pump replacment recommendation.

If it's your daily driver, then definitely get the ACDelco. I've installed them in my past three daily drivers. Each time was pump failure and tow home, thank you AAA. I've never had to replace them more than once.

If it's more of a toy and you need to be cheap, I'd get a rebuild kit off eBay. Grumpy is running thanks to a $30 kit from Global Auto.

It's an expensive part for your year model, even a third party manufacturer like Airtex. It's a PITA to replace. It's really really expensive if you have a mechanic do it. If I recall correctly, SoCalli's recommendation is always to go with an OEM pump. I have yet to follow his advice, foolishly perhaps as I'm on my second pump since the original gave out. the third party parts are a bit of a crap shoot. Might last forever or less than a year. Even if you get it replaced on warranty, you still have to drop the tank again. If doing something like replacing a pump is one of those things you would just take in stride, then go budget. If it's one of those thing you think you might never want to have to do again, go OEM.

ONLY, Fit an AC Delco pump.... Anything else 'is' inferior and can leave you stranded at any time.... with a huge tow charge to get home, it`s just not worth it.

Change your fuel filters every 20k, this will prolong your fuel pump life.

Hmmm. The reason I was thinking that SoCalli was an OEM proponent was that one of the replacement pumps that crapped out on me was an AC Delco. I must've drawn the black bean.

Thats all?

Man the pump alone for my 98 has a list price of $780 for the Delco.

Which is what I would have to pay if my uncle didn't run the parts store.

I only actually paid $360

Thanks for your advice about using ACDelco fuel pumps on my GMC van. If wondering, I did get its gas / fuel filter changed yesterday (at 88K miles). Was told to change its gas filter every 20K miles as well. Thus, putting less strain on its fuel pump. Was also told to NEVER allow its gas tank level to be below 1/4 full. When the needle drops below 1/2 tank, fill her back up again. Was also told that levels above 1/4 tank (the higher level the better), it also puts less strain on its "in tank" fuel pump. Thus, lowing sudden blow out risks even more.

We had a previous '95 Safari van - from '96 to early 2003. Always replaced its gas filter at 20K and always kept its gas tank above 1/4 tank. And, we never had fuel pump problems in this vehicle. She "rusted out" before it started mechanically breaking down.

Thanks for your advice about using ACDelco fuel pump on my nert 2001 AWD Safari van. And suggesting we "proactive change" its fuel pump at 100K miles. We'll budget for a fuel pump change at 110K (or so) miles.

or go with an exetrnal (inline) electronic fuel pump replacement? For different designs of fuel pumps for my 2001 AWD Safari van, surf:
Spike, this part of your question is one I've asked several times and there doesn't seem to be anyone who has installed an in-line electric pump because my question has never been answered or has been overlooked. Of course I don't have that problem since I run a carb. but have followed the fuel pump replacement issues in many threads and have asked why go through all that trouble,,forget the intank pump and install in-line. There may be a good answer as to why this isn't the best thing to do or the easiest but haven't heard it yet.

When ever something packs it in on anything I've ever owned, I always take the approach of how can I improve this.
Intank fuel pumps are a pain in the ass simply because of there location. Why wouldn't you replace it with an inline.
If your replacement fails all you have to do is replace the pump and you could mount it anywhere for easy servicing. An inline pump replacment just makes to much sense.

Does to me also but have never heard anyone here who has done it. Like I said,,seems much easier but as I also mentioned,,there may be a reason why no one has taken the easy road.

The answer to the inline fuel pump question has always been another question. Will the inline fuel pump pull enough fuel through the intank fuel pump to maintain the required 55 - 60 psi? Seems nobody has spent the cash to buy and install an inline to try it.
