Guys that run the Fram HPG1 style filter for fuel ?

Your using the stock sending unit? If so I hope the straw is bigger than 5/16. The easiest way I have found to use the stock sender/pick-up is to cut off the "nipple" and the straw. Drill a 3/8" or 1/2" hole where that used to be and use a piece of 3/8" or 1/2" SS tubing and bend up a new pick-up tube then braze it to the sender. Then you can use one of the hard-tube adaptors or just a regular compression fitting to attatch it to the new aluminum fuel line.
