Hi, I've seen alot of people mention fitting a walbro 255 to their MK2 meganes. I bought a walbro and it's 10mm too long to fit. Is there a compant version? I've googled and can't get an answer. I've a DW65C which is a direct fit but Ive a fuel pressure issue and all we've left to rule out is the DW65C. For reference, the DW65C is 113mm and the Walbro is 123mm
