Fuel Filters

[andrewb70]

That looks alot like my 97 GMC filter.

The list of applications is about a mile long for this filter. Here are the specs:


Part Number: 33481 UPC Number: 765809334816 Principal Application: GM Models (83-07), Jaguar (97-07), Land Rover (99-04)
Style: Fuel (Complete In-Line) Filter Service: Fuel Height: 4.290 Outer Diameter Top: 2.170 Outer Diameter Bottom: Closed Burst Pressure-PSI: 300 Max Flow Rate: 1 - 2 GPM Nominal Micron Rating: 4


Taking the flow rate and choosing the middle of the range, 1.5GPM, that works out to 340 L/hour. A 255L/hour pump will easily support 600flywheel HP.

You might think that since I changed it over the winter that I'd remember, but I'm not sure. I don't think it used quick disconnects. I'll have to double check.

You are correct. Same filter. www.rockauto.com has a all the data. Neat site to reference many parts.

There are some very inexpensive parts available to adapt the later model filter/regulator combos so that the quick disconnect can be used. ls1tech.com has a bunch of useful info.

I work at a shop, so I actually have access to the equipment to make the quick disconnect ends on the lines. Of course, since I don't need to it doesn't matter, but I've considered it.

[ErikSOCAL]

this site rocks. I am going with that filter for the exact reasons listed, don't need no stinking polish and I like off the shelf parts.

I would like to see some data to back up this statement. This filter has been used, in conjunction with a Walbro 255L/hr pump, to feed a 600HP (flywheel) 496 big block chevy. I suppose if you had a 1000RWHP engine you would need something else, but for the 90% of builds out there, this filter will work just fine.

As for using the 2001 truck filter, I believe it will have the quick disconect style fittings on it. That will make it more difficullt to integrate into your fuel system.

No data, but consider this. That filter has at most a 10 micron paper element. There is no free lunch, and a 10 micron filter that size is going to be a restriction with its low filter area, especially when it gets dirty. Restrictions in the fuel system cause heat build up in the fuel. I have been battling heat saturation in my car and have replaced every "it should be big enough" part with overkill parts.

Thank you. I was concerned about this relatively small surface area, and the flow demands of the bigger engines.

Not to take anything away from the 'vettes, but a 350 making 400 hp and a 454 or larger, making 600 or more hp, is a big, big, difference in fuel demands. Especially when you consider that many built BB engines are not as efficient, so their BSFC goes up, and therefore the fuel demands (volume).

I will say this again. This filter has been used countless times on a big block making 600HP, with no pressure drops at WOT.

Thanks Andrew. How often has it been changed? Just curious. I have the means to measure, very accurately, flow rates through this, but I am concerned about doing a setup with fuel with all the flammability issues, in the garage.

I can measure flow rates to +/- 0.05%...up to 800 GPH.

I use that itty bitty filter on my BBC with a Walbro 255LPH pump. I have rock steady 45 PSI fuel pressure. Car's gone 127.5 at 3640 lbs at the track so someone can figure out the HP although I have a pretty good guess

I replace the filter once every one or two years. The prefilter should be getting most of the junk.

[ErikSOCAL]

which fitting does this need into the filter housing? one with an oring? fittings have been my nemisis lately.

Yes, the o-ring type fittings. I think they area called Saginaw. So you would need a Saginaw to AN6 adapter.

The engine doesn't determine the flow rate through the filter on EFI engines, the pump does. You could have a 6 cyl or a BBC, it doesn't matter, XY pump will still supply a given gal/hr at a given pressure setting. All that changes is how much is then sent back to the tank via the return.

I hate to be a pain, but I can't find anything by searching for this fitting. Do you have a part number? Thanks

But the engine/chassis does determine the fuel needs.

[Fuelie Fan]

Which, like i said, affects only how much fuel gets sent back through the return line. NO effect on filter selection.

[ErikSOCAL]

ok, fittings, fittings, fittings...
a friend of mine determined the fitting needs to be 16mm X 1.5mm pitch for the filter by googling the filter and p/n. He found p/n 3008 listed the specs for a tube nut that fits this filter. Here is the link..it also has a ton of other fittings which might be useful for conversions:

From there he wasn't sure if it took an oring so I looked through summit and found the below listed parts. From andrew, I guess we know it should be the first or second one, but can someone please confirm this! Choices 2 and 3 the pictures seem reversed... the specs list oring for #2 but the oring pic is in #3 which doesn't list oring in the specs... i didn't go to the company website yet (work, shhh!) thanks -

I have the Aeromotive 10M, I like the fact that it can be opened up, to see what, if anything, is in the fuel. plus the large nonrestrictive element should be easier on the pump, and can be replaced for 15 bucks.
So I paid more initially, but replacement element are cheap.
and look..... it matches my regulator so nice

[Hammered]

While we're on this subject, does anyone know an OEM application for the Aeromotive 10 micron filter so that I can get it locally through NAPA or another parts store?

It's probably like my SX filter which uses a Purolator 10 micron paper element inside. The element is stamped with Purolator and a part number-- unfortunately that particular element is not available "over the counter" because it's a custom produced part just for SX. Believe me, I tried to buy them elsewhere but even a large Purolator dealer here in town could not get them for me.

I ended up buying a case (12) of the elements and they cut me a deal. You might want to try that.
