Problems with aftermarket fuel tank

[Satan bianchi]

Anyone else had a problem with fill tube on aftermarket tanks...I ordered a 78 tank from summit ...looks identical ...except fill neck is Def much larger...the old rotted tube that came off was..1"3/8...won't fit on new tank...bought 1"1/2 marine fuel line ...dosent seem like it's going to fit either ...and is too loose on fill neck in the 1/4 panel...I ain't really trying to rig anything either

Seem to recall the diesels having a larger fill tube than gas?

 

[sweetk30]

some older tanks were smaller size tube.

is it for the blazer in avatar pic ?

I know some replacement radiators come with a rubber size reducer bushing .

I didn't know there was a difference in necks summit just had it listed as 31 gal 78 blazer tank...any way to make it work we would be great

The old tank had made in Canada stamped in it ...I been for for two days now trying to figure this one out

Its,driving me nuts epically after spending 45 bucks on two feet of 1 1/2 inch fuel l

Wrong tank for a 78, should be 1 1/4 neck, vent line is bigger also.
Otherwise identical.

This is correct happened to me on my 73. Used different sized hose to make bushings to adapt never leaked

 

[Satan bianchi]

It appears to be bigger then 1 5/8ths after buying 50$ more hose ...still don't fit ....I'm ready to lose it

 

[blazer74]

Wrong Tank.

 

[blazer74]

Call Summit

 

[Satan bianchi]

Called summit ...it is indeed wrong year and diesel...they listed it wrong so ...I'm waiting for them to pick it up ..and the new to ship from manufacturers

 

[blazer74]

Perfect. You can still use the 1 1/2 hose on the filler.
It will tighten up.
