Fuel pump aftermarket part numbers

Hose Harvest & aftermkt pumps have same size barb as Carters

Just to get the submersible hose, I got another MC fuel pump module with a burned-up Carter fuel pump. Whole module was gonna be thrown away.

(a) the hose that comes with the Carter pump fuel module from MC is 1/4” on one end, and 5/16” on the other, and
(b) the aftermarket pumps have the same barb size as the Carters.

Hope this is helpful.

I think I've got some updated info.

Just to get the submersible hose, I got my hands on another MC fuel pump module with a burned-up Carter pump that was gonna be thrown away.

To harvest the ENTIRE hose, I had to destroy the barb on the burned-up Carter pump that came with the module I just picked. More on that below, but the this pump and my old Carter pump are identical, ("323 Made in USA"), with same sized barbs.

OK, in the 1st pic notice that the barb on my old Carter pump and the module barb are indeed different sizes. A 5/16" EFI hose fits perfectly on the Carter pump barb, while a 1/4" EFI hose fits perfectly on the module barb. You cannot IMO get a seal with a 5/16 EFI hose clamped on the module barb.

In the second pic notice that the harvested hose is set up for the different sized barbs on either end!

In the 3rd pic my original pump is on bottom, with the burned-up one I just picked up on top. The top hose is much more flexible and less likely to kink, but it is still heat welded on both ends, and you can't just pull it off.

It will be easier to reuse your old hose if it is like the one on the module I just picked up instead of like my old one. It's softer. To reuse it you can cut it, and go with a shorter hose, but the harvested hose seemed quite a bit shorter than my old hose was before I cut it in half -- and you need some extra in there -- so I cut the brass barb off the burned-up Carter pump I just picked up. Then I drilled the cut off barb from the inside till it started to spin inside the hose, then I crushed it a bit with pliers and was able to pull it out.

I hope this clears some things up. Thanks bigmac, rhsprostar, and other for your ongoing commitment to this cause. BTW, sorry about the overuse of the word "harvest." Great Neil Young album though!

Cheers Mal,
I'll send you an email, but maybe we can both get one and combine shipping.

Hi Shane, google is your friend. I too have been looking for a spare pump, and I found this place that will ship to the land of Aus. I haven't ordered one, yet but intend to soon. Shipping is only about US$26

Thanks big mac, I had already looked to purchase from Amazon, but they only ship either pump to the US.

G'day.
Looking for assistance with regard to the "possible" failure of my fuel pump. It seems that all the replacement pump model numbers (e.g. EP356), that are listed within this thread don't cross reference here down under. Is there any where like Skidim or an auto parts store that I may be able to order one online or get someone to send me one? After some research and realising the difficulty in locating a repalcement here, I thought I had better have one sitting on the shelf, so I don't have the boat sitting idle for weeks until I can locate and replace the pump. I would also like to note that I have almost 600hrs on my boat and I have run out of fuel twice, so I may never have a problem but I think it is a relatively cheap insurance policy to have a pump just in case.

If you can order from Amazon.com in the US, they have both the EP356 and the E2044.

Thanks for the tip bigmac, I'll let you all know how it turns out.

The 1/4" barb is plastic. When I replaced the entire module I forgot to notice if the new module had a different sized regulator connection since the hose is different (clear corrugated vs hard plastic).

[rudaire]

I haven't really looked at the unit, because I haven't had mine out.. But is it possible to replace the 1/4 inch barb with a 5/16? I realize it connects to the short 90 degree bend that ends in a quick disconnect fuel fitting outside the tank. Can that whole piece be re-made and sealed up in the top of the module? Is the factory 1/4 barb plastic or metal??

I sure wish someone else would try to put 5/16 ID fuel injection hose on a 1/4 barb to either back me up or put me in the dog house.

By the way, the service mgr at my MC dealer asked how my fuel pump change went, and I told him it was fine but mentioned the submersible-hose issue. He said that if you get a year out of it you're ahead since 500+ bucks on a new, whole module. But I still want to put proper submersible hose in if we can make it work.

Maybe it will work if its much more soft/compressible/squishy than the 5/16 ID fuel injection hose I got at autoparts store.

5/16 ID fuel injection hose would not blow off necessarily, but would surely leak, IMHO. You probably just can't get the larger inner diameter to uniformly compress around the 1/4 barb. There will be a fold.

Has anyone used this Gates in tank fuel hose? I noticed a post somewhere that it was bought from Napa. It is about $17 per foot. It comes in a 5/16" ID. I was curious if it would fit the 1/4" fitting on the regulator. Also, how flexible is it?

According to Stu, it will blow off the end of the barb.

Be careful with the fuel line that goes from the old pump to the regulator inlet - you'll need to re-use it. Detach if from the old pump and reattach it to the new one.

Just bought AC Delco ep356 to replace the stock carter fuel pump in my 06' 197 with MCX engine. Any advice or tricks I need to know for installation?
