Anybody run into this? The new Walbro fuel pump I received is longer than the original one. The design of the white plastic piece is different. I don't see how this can be fit into the bracket. Right pump or wrong pump? Suppose to be a stock 155 LPH liter pump.

You might have the small tank and you got a large 18gal pump????

Just throwing it out.

I got a stock walbro in front of me on my desk (dont ask) and it looks more like your new one with ''stages'' , the plastic isnt flat out like your old one.

Matt emailed that it's suppose to be the right one. But it does not want to go into the bracket because it is way longer than the original. I hesitate to bend the bracket and force it. It is not the same pump SHOsource shows on their web site; something has changed.

Anybody have a picture that shows this pump installed in the bracket?

Get on the horn with Walbro.

FWIW, mine looked different than the stock one as well, but it works just fine.

Walbro wont know whats going on since this is not one of their applications.

He needs to contact SHOSource like he did so we can help him.

Spoke with Walbro. They said the one I received is the wrong pump. It's a Walbro 516 (see 3rd picture). The correct pump for the SHO is a 526. The 526 is still a good part number and stocked at their distributor, according to Walbro.

For future reference, Walbro part numbers and contact information:

Walbro 526 -- SHO fuel pump, stock 155 LPH, pump only

Walbro 526-1 -- fuel pump + installation kit (strainer, black fuel line clip, white fuel line clip, o-ring seal [all needed], and two hose clamps, 6" submersible 5/16" fuel hose [not needed], and pump cushion [nice to have but old one usually reusable]

Walbro 400642 -- installation kit only


Walbro customer Service: (989)872-7254

The pump that was sent has an RFI filter which the stock replacment does not.

The ones sold are higher flowing then stock.

I have been able to install it by flexing the bracket. The other option is to remove the pulse dampener which is what the hose is for.

Here's some more information that may help clear up the differences:

The original factory SHO pump was a Walbro model 5526.

The current Walbro direct replacement pump is the model 526 (they dropped the leading five from the earlier PN for unknown reasons), rated 140 LPH. So what SHOsource sent is not correct if what you are (reasonably) expecting is a direct replacement. But read on, there is more to the story...

SHOsource sells three different pumps, and all are upgraded capacity units: a 155 LPH (model 516), a 190 LPH, and a 255 LPH pump. All three have the same form factor, but that is unfortunately 0.375" longer than the original pump. They don't sell the 140 LPH direct fit replacement, at least for the time being.

Now, here's my beef: The description on the SHOsource web site doesn't really let one know the replacement they sell is an upgrade, and it is 3/8" longer. If they had shared that detail up front, I would not have been scratching my head over why the new one does not want to slide right into the bracket and spent all this time learning more than I've ever wanted to know about Walbro fuel pumps.

That criticism aside, Matt was kind enough to call me on his own initiative today to talk about the fit. He indicated that on two upgrade pumps that he has installed, the longer pump squeezed in without too much difficulty. My bracket seems to be tighter; understandable, they are just sheet metal and I'm sure there is a lot of tolerance. Now that I know it's not suppose to be a direct fit, I'm off to the garage to see if I can coax this 516 pump to work.

SHOsource sells these pumps as performance upgrades... Not direct replacements.

If you bought lowering springs would you call the manufacturer to tell them that they are shorter than your OEM springs?

Some while back when I installed my 155 I too had the same issue, And even though I knew removing the fuel pump dampner would probably not cause any issues I called around and asked a few local guys... Nobody had a definete answer, but somebody had Matts number and he was happy to explain what what I needed to do.

With a car with such limited aftermarket we need to make do with what we can get.

Your analogy with lowering springs is not comparable to this.

The gripe I have is with the description of these pumps on SHO source's web site. As I said before, they really need to disclose that the pumps they are selling are not the same form factor as the original. One more thing, picture they show is the correct (original) form factor pump, not the longer pump they actually ship. I looked at that photo carefully before I ordered.

The direct replacement model 526 is readily available, so there is no need to "make do" when it comes to the fuel pump.

There is a need to "make due" for an upgrade as stated for just about everything on this car. I don't believe SHOSource is at fault for you not knowing that a 155 pump is higher flowing and therefore not direct replacement...just saying.

They should. It is in their interest not to have to deal with after sales support when they can avoid it. And if their picture shows the stock pump and not the one they sell then they need to fix that.

This whole sentence should be removed too, especially since Walbro made the stock pumps:
Don't go for a stock one, go for a Walbro which is a very good reliable pump and can handle any mods you throw at your SHO.
And the last sentence in the description doesn't jive with the quote above:
The fuel pumps have a 1yr manufacturer warranty but they will have to be sent in for testing due to a high amount of returns.

The end of the description should just say "Good luck!" :nut:

Wrong. If it's not a direct replacement, drop in unit, the customer needs to know. There's nothing in the SHOSource listing that says it'll require modification to install, or that it won't look exactly like the stocker, but will fit and perform just fine.

FWIW, Summit sells the 526 pump only, and 526-1 kit, if someone wants to order an exact drop in replacement.
