Product Details

The Walbro 128-3025 is a 12mm outside diameter (OD) fuel pump fitting designed as an adapter for Walbro GSL series external inline fuel pumps. This precision-engineered fitting provides a reliable connection solution for high-performance fuel system installations.

Key Features:

  • 12mm outside diameter for secure fuel line connection
  • 10mm x 1.0mm straight thread design
  • Compatible with Walbro GSL391, GSL392, GSL393, GSL394, and GSL395 inline fuel pumps
  • Zinc-plated steel construction for corrosion resistance
  • Requires copper washer for proper leak-proof sealing (not included)

Important Installation Note: This fitting features a straight thread design, not a pipe thread. A copper washer must be used to ensure a proper leak-proof seal. The fitting does not tighten like traditional pipe threads, so proper installation technique is essential for optimal performance.

This OD fitting is an essential component for custom fuel system builds and performance applications where Walbro external inline fuel pumps are used. The universal design allows for flexible installation configurations to meet specific fuel delivery requirements.

Shipping sucks

Thank you

Great experience the firat time ordering. The second time ordering, its already been a week past delivery date and still nothing. And for some reason instead of shipping tobmy state, the shipped from california to south carolina and im assuming they will be coming to me next

The site keept timeing out.

Your prices are lower but your shipping brings the total cost almost the same as Amazon. Fedex appears to take one to two days longer to complete delivery. I did not go for one shipping and overall I am very satisfied with the purchase and receipt which put the products at my door.

Straight forward so far so good. Update: Upon receipt of shipping confirmation email I received a tracking number but no ETA date or time and no apparent way to find this information so I could arrange for somebody to be present to receive item. I reached out to customer service through email and never received any form of response beyond auto reply that my inquiry was received and a ticket number was assigned. Fortunately delivery did work out with my schedule and driver was very professional and helpful. I would order from autoplicity again in the hopes my inquiry had just slipped through the cracks and future orders would have some form of ETA when and if a person is required to be present for delivery. Time of order, to shipping, to receipt of product was very quick (within a week).

Quick checkout offering Amazon or PayPal checkout very convenient

Awesome prices always deliver on time !!

Totally amazed. It made it to my house in TWO days AND they had the LOWEST price. I was nervous cuz ive never heard of them. order number 4463
