Does the pick up tube fit down inside the filter???? Should the pick up tube slide inside?


The pick up tube should fit through the hole in the top of the filter. It sounds like you're saying yours doesn't fit even without the rubber seal in place. I imagine the solution will be to drill out the hole in the top of the filter so it will fit being careful to catch or clean out any chips in the process. Does the grommet with the bypass valve fit in the other hole?

Thanks for the info. The filter does NOT fit over (down into filter) on either side. I will enlarge one of the filter holes as you suggest. It JUST DIDN"T SEEM RIGHT!

Again Thank you all!

I agree Chris, that the fitment of the pickup seal seemed questionable at best. Just getting the mini-sump pressed deep enough to engage the nuts on the threads took a lot of pressure, and the seal seemed to fit pretty cockeyed. The bottom diameter of the seal doesn't match the recess in the filter. If I recall, I replaced the studs in the case with longer studs in the sump hardware kit (this is not called for in the plans) just to make it easier to get the nuts on.

I haven't yet changed my oil for the first time. When I do so I imagine I'll initially drain the sump oil from the oil return line from my oil separator (or the plug that would otherwise connect to this line) before removing the mini-sump. Still probably a messy process.


Did you end up modifying your upper seal to make the fit better? My upper seal sits on the pickup tube so crooked & loose you would think its not made for this purpose...and there is no way its going to sit flat or flush on the filter...the seal just doesn't appear that it was made to go with the filter...very odd.

Yes actually, I chamfered the bottom of the oil seal to fit better into the top of the filter. This both made a better seal, and made the sump easier to install by reducing some of the spring pressure when fitting the sump.

Has anybody measured how much oil this sump holds? Looks like about a cup. It would be nice to be able to dump in the whole 3 quarts.

This is exactly what I am seeing. Not a flush fit at all and does NOT seem to be the proper seal. This looks to be a VERY poorly engineered product. Any suggestions?????

How does one even know the oil is going through the filter. ??????
I am getting about 60 psi on startup which does NOT vary with RPM......something is wrong there. THEN my oil temp goes up to 250 and my oil pressure gradually, over ten min. of operation, drops to 11 psi regardless of rpm.
I cleaned my oil pressure plungers and passageways with no change.
Help .....I am lost here.

The mini-sump comes with a re-usable filter and I was wondering what solution builders are using to clean this filter with?

It's just a really fine metal screen. Gasoline works about as well as anything.
