92 22RE 4WD 120K

Wondering if I should replace fuel pump at 120K since I am having my chassis/frame completely undercoated by Ziebart this fall and everything underneath will be a PITA to work on after that. How many miles/years do you all have on your original pump? How many hoses (that I will replace also) are attached from the pump/tank to the feed & return lines? I assume OEM is the only way to go? Reason for undercoating is that truck was bought from AZ and is completely rust-free, but I am in NJ & road salt is the #1 cause of death for these great old trucks. Thanks!

 

No way to tell if it's original with my truck's history, but I replaced my fuel pump sometime between 350,000 and 400,000. The one that was in there was Denso and looked old so it could have been original unless someone sprang for OEM. It worked fine and is currently powering a Geo Metro I got for free.

I replaced mine before a 2,000 mile road trip with a Denso one purely for peace of mind.

 

OEM fuel pumps last a long time under normal use. What usually kills these fuel pumps is letting the truck sit for long periods of time with old gas causing trouble.

It is up to you if you want the piece of mind of installing a new pump.

It may be good to open up the tank to see the cleanliness of the inside as well as checking the pump intake filter strainer. Over time, the pump filter strainer can deteriorate and fall to pieces.

Some people have had success with aftermarket fuel pumps, but it is hard to beat the reliability and quality of an OEM Toyota (Denso) fuel pumps.

 

 

I have two pumps going strong at over 200,000 miles
