*Little background story*
I was out of town, walboro 255 pump died. had the car towed to a firestone who replaced my whole pump canister assembly with a unit from Airtex (E7142M). Couple weeks later i noticed a fuel leak back at the tank and my gas guage has been reading wrong.
I decided to pull out the unit and compare it to the stock unit they pulled out. I took pictures of what i noticed to present to the forum.
canisters side-by-side:
as you can see the Airtex unit is slightly longer and has a different shape. also the level float is slightly shorter.
again side-by-side: showing the difference in the design of the sock filter.
one main difference is this check valve type vent in the Airtex canister:
The FPR seems basically identical and is 58psi.
On to the pumps: 255L vs Airtex pump
as you can see the Airtex pump is a good bit smaller, but from what i've read will flow more than the stocker. (likely not as much as the 255). I cannot confirm or deny this though. The designs however are much different.
bottom of Airtex pump:
bottom of 255l pump:
At this point i reinstalled the Airtex unit into my tank and everything seems to be sealed up (hopefully i fixed the leak).
I have plans to hack up my oem unit and install a bosch 044 pump and swap back.
But this does seem like an adequate alternative to the factory unit for anyone needing to replace theirs for whatever reason.
after doing all this last night i went and filled up the tank, i'll report back on whether or not the fuel gauge is now reading right. So far so good.
