Questions about Tanks, Inc with GPA-4 pump
 

I purchased the Tanks, Inc EFI tank with GPA-4 pump to replace my mallory 140 (which died AGAIN last OCT). This tank appears to be very high quality.. I really like it!

I have configured the pump according to the instructions but it appears to be roughly 1/8" too long and as a result the pump is hitting the bottom of the tank. I contacted Tanks, inc yesterday and they said this "shouldnt" happen and to email them pictures. They havent responded and were not helpful.. at all...

The only solution I see is to remove the pump and cut 3/8" or so off the housing "nipple" for the supply which would allow the pump to move further up once the black tube was trimmed more. Right now the pump inlet is butted up against the nipple on the housing. See the picture with the screwdriver pointing in this spot.. Has anyone else run into this?

One question, cause I can't tell from the pics, is the inlet filter completely engaged? It would still be close, but with the gasket, and another 1/8" or so engagement it would probably be ok. Probably there's some of the dreaded "tolerance stack" happening here.

That is odd - I have the 255 LPH pump with a Tanks Inc tank in my 69 bird and had no issues with bottoming out - hard to believe the bird tank would be deeper. Are you able to trim the barbed nipple that comes off the plate? Also, the gasket will help a little.

On a second look at the pictures, I would say the outlet hose from the Fuel Pump to the flange just needs to be shortened
a bit more for sock clearance at the bottom of the tank.

You probably shouldn't trim that fitting. I believe it has a barb at the end (and only at the end) to aid retention.

This is the same thing the guy at Tanks asked me. Just checked, again, and the filter appears to be all the way in.

Thats what i was thinking... Trying not to "bubba" the dang thing but I dont think it will work properly as-is...

IIRC, the barbed fitting on the plate(top) is brass with multiple steps

If I was going to engineer my own setup I wouldnt spend $600 on a package that shouldnt need engineering or modification.. :rolleyes:

Is the nub on the pump sticking completely through the hole in the filter?

When I installed the GAP-4 module into my Tanks Inc tank, I did have to trim the outlet (black) hose to get it to fit properly. In fact the instructions specifically stated that you would need to measure first, then trim to length.

If due to the length of pump output nipple and barbed fitting, you no longer have room to trim the output hose, you may consider gluing a couple cork gaskets together. The pickup sock should sit very lightly on the bottom of the sump without being crushed in any way.

I agree, I have a Tanks,inc gas tank for a 64 GTO in the car.

I modified the single pump opening so that I could run a Pump Mount
with two E-85 compatible 450 liter per hr fuel pumps.

Not that difficult. And my wife did not spend $600 on the Tanks,inc parts.
She just bought the tank, I did the rest.

Interesting.. Shocked that they didnt recommend this when I called.

I went out and yanked the feed tube to the pump off. I was able to trim it down a little further and my assumption that the pump and housing were butted up was incorrect! I can get it to about 5 7/8" with the units butted up to each other.. Guess this will work with even without a thick gasket... Looking forward to getting this tank in! Thanks guys
