Two filters in a FI supply line?

[hootsk]

I've got an '87 GMC Suburban, 2WD with the 350 and 700R4. The fuel supply line is 3/8" with M16-1.5 connectors with the proprietary GM TBI o-ring seat.

The line rusted out, and I bought a kit from RockAuto to replace it. The kit is identical to the OEM parts — except the line is in sections so it'd fit in a shorter box.

The problem is the manufacturer left out the M16-1.5 union to join the aft sections. A double-ended M16-1.5 union with the GM TBI seats is not a common part. But the fuel filter has those connections.

My question is, can I use a second fuel filter to join the supply line's two aft sections? Should I drill a hole through the inside to relieve the extra pressure?

Thanks in advance.

sounds like a creative way to solve the problem and should be fine as long as the drilled filter is totally cleaned of any debris.

Could I install it without drilling it?

maybe too restrictive, you can try and then do a fuel pressure test

The manufacturer overnighted the missing union the free of charge, so I never had to try the drilled fuel filter trick. Fineline of Nova Scotia, Canada.

great better solution than the two filters
